    Japanese Knife Christmas Gift: 5 Beautiful Choices from a Professional Chef

    Asaoya Yaichi X’mas Sale

    Christmas is approaching, and finding the perfect gift for someone special is not always easy.

    A Japanese knife can make a wonderful Christmas present. It is not simply a kitchen tool, but something that can be used, appreciated, and treasured for many years.

    After more than 25 years working as a professional chef, I have used many different Japanese knives. Some have impressed me with their cutting performance, others with their craftsmanship, and some simply because they are beautiful to look at.

    Today, I would like to introduce five Japanese knives from Asaoya Yaichi that I personally recommend as Christmas gifts.

    These are not necessarily the five most expensive knives in our collection. They are five choices I genuinely believe would make wonderful presents.

    Of course, choosing a knife for someone else is not always straightforward. Everyone has different cooking habits, preferences, and levels of experience.

    That is why I have considered not only appearance but also practicality, maintenance, and the type of person who might enjoy each knife.

    Our limited-time Christmas Sale begins on Wednesday, 14 October 2026, at 12:00 AM (Queensland time), so this is also a good opportunity to introduce some of the knives available at Asaoya Yaichi.

    If you would like to explore our collection, please visit our Japanese Knives Australia collection⁠.

    Japanese Knife Christmas Gift No. 1 — 180mm Santoku VG10N 33 Layer Damascus Green Marble Handle Rainbow Spacer


    View more details on our website

    My first recommendation is one of the most beautiful knives in our collection.

    The 180mm Santoku VG10N 33 Layer Damascus features an elegant Damascus blade and a distinctive green marble-style handle decorated with a colourful spacer.

    What makes this series particularly special is its limited availability.

    Our supplier, Ishizuchi Kanamono Seisakusho, receives only small quantities from the blacksmith responsible for producing these knives.

    At Asaoya Yaichi, we currently have four different variations available, featuring red, orange, yellow, and blue spacers.

    We have only one knife available in each colour.

    The 180mm Santoku is also a practical choice for everyday cooking.

    Personally, I believe 180mm is a very comfortable size for home kitchens. It is long enough for most everyday preparation while remaining manageable for people who may find a larger Gyuto slightly intimidating.

    Vegetables, meat, and fish can all be prepared comfortably with this type of knife.

    Another advantage is the VG10N stainless steel blade. Compared with traditional carbon steel, it is relatively easy to maintain because of its corrosion resistance.

    Of course, even stainless steel knives should always be cleaned and dried properly.

    For someone who enjoys cooking and appreciates beautiful kitchen tools, I believe this would make an exceptional Christmas present.

    Personally, I find the combination of the Damascus blade and colourful handle particularly attractive.

    It is certainly one of my favourites.

    Japanese Knife Christmas Gift No. 2 — 180mm Santoku Aogami #2 Green Micarta Handle with Turquoise Spacer


    View more details on our website

    My second recommendation has a completely different character.

    This 180mm Santoku features Aogami #2 carbon steel, a beautiful green Micarta handle, and a striking turquoise spacer.

    Like my first recommendation, this knife comes from a blacksmith whose work is available only in limited quantities through our supplier.

    Personally, I find the combination of the deep green handle and turquoise spacer particularly beautiful.

    There is something about its appearance that reminds me of the Japanese aesthetic of wabi-sabi, an appreciation of simplicity, character, and understated beauty.

    However, the real attraction of this knife is not just its appearance.

    Aogami #2 is a traditional Japanese carbon steel appreciated for its cutting performance and sharpening characteristics.

    Over the years, I have used several different carbon steel knives in professional kitchens, and I still enjoy the feeling of a well-maintained carbon steel edge.

    There is something satisfying about using a knife that requires a little care but rewards that attention with excellent cutting performance.

    However, carbon steel is not necessarily the best choice for everyone.

    Unlike stainless steel, Aogami #2 can develop patina and rust if it is left wet or poorly maintained.

    For that reason, I would recommend this knife to someone who already understands basic knife maintenance or genuinely enjoys looking after their kitchen tools.

    If you are interested in learning more about the differences between Japanese knife steels, I have discussed this subject in my article about Japanese Knife Steel.

    For the right person, this knife offers a wonderful combination of traditional Japanese steel and contemporary design.

    Japanese Knife Christmas Gift No. 3 — VG10 Polished Hammered 67 Layer Damascus Green Handle Series


    View more details on our website!

    My third recommendation is particularly interesting because it offers the opportunity to create a matching knife set.

    This beautiful VG10 series features a polished hammered finish, 67-layer Damascus construction, and elegant green handles.

    At Asaoya Yaichi, we offer three different knives from this collection: a 180mm Santoku, a 210mm Gyuto, and a 135mm Petty.

    All three are attractive knives individually, but I think they become even more interesting when considered as Christmas gifts.

    For example, combining a Santoku with a Petty would make a beautiful and practical present for someone who enjoys cooking at home.

    The Santoku can handle most everyday food preparation, while the smaller Petty is useful for more delicate work.

    Alternatively, a 210mm Gyuto and 135mm Petty would be an excellent combination for someone who prefers a slightly longer main knife.

    Personally, I do not think most home cooks need both a Santoku and a Gyuto from the same series.

    Their uses overlap considerably, and I would rather recommend two knives that complement each other.

    After working in professional kitchens for more than 25 years, I have come to appreciate the importance of choosing knives according to the work they actually need to perform.

    A larger collection is not necessarily a better collection.

    In fact, two carefully selected knives can be more useful than several knives that perform almost identical tasks.

    I have previously shared my thoughts on different Japanese knife shapes, including the versatility of the Gyuto, in my article Japanese Knife Shapes: 5 Powerful Lessons From 25 Years.

    Another reason I like this series as a Christmas gift is its appearance.

    The matching green handles and Damascus blades create a beautiful combination, particularly when two knives are presented together.

    For someone who enjoys cooking regularly, I believe this would be a thoughtful and practical gift that could be appreciated for many years.

    Japanese Knife Christmas Gift No. 4 — Ginsan Nashiji Forged Magnolia Octagonal Handle Buffalo Horn


    View more details on our website!

    My fourth recommendation is for someone who appreciates the traditional appearance of Japanese knives.

    This series features Ginsan stainless steel, a Nashiji blade finish, and a traditional octagonal magnolia wood handle with a buffalo horn ferrule.

    The appearance is unmistakably Japanese.

    Personally, I find the simplicity of this design particularly appealing.

    Unlike the colourful handles of my earlier recommendations, this series has a more traditional character.

    There is no need for elaborate decoration. The forged blade, textured finish, and natural wooden handle already give the knife a beautiful presence.

    At Asaoya Yaichi, we offer four different knives from this collection: a 210mm Gyuto, 180mm Santoku, 165mm Nakiri, and 120mm Petty.

    Once again, combining two complementary knives could make a wonderful Christmas present.

    For example, a Santoku and Petty would provide a versatile combination for everyday home cooking.

    A Gyuto and Petty would also be an excellent choice for someone who prefers a longer main knife.

    Alternatively, someone who enjoys preparing vegetables might appreciate the traditional appearance and specialised shape of the Nakiri.

    Ginsan is an interesting steel because it combines good corrosion resistance with cutting and sharpening characteristics appreciated by many Japanese knife enthusiasts.

    For someone who likes traditional Japanese knives but does not want the additional maintenance associated with carbon steel, I think Ginsan is well worth considering.

    I have previously written about this steel in my article about Ginsan Steel.

    The Nashiji finish is another distinctive feature of this series.

    Nashiji literally refers to a pear-skin-like texture, and it gives the blade a traditional, understated appearance.

    If you would like to learn more about this finish, you can also read What Does Nashiji Mean on a Japanese Knife?

    If the person receiving your gift appreciates traditional Japanese craftsmanship, this series would certainly be worth considering.

    Japanese Knife Christmas Gift No. 5 — 180mm Kiritsuke Aogami #2 Kurouchi Walnut Octagonal Handle


    View more details on our website!

    My final recommendation is a little different.

    If I were choosing a Japanese knife as a Christmas gift for a professional chef, this would be one of my strongest candidates.

    The 180mm Kiritsuke Aogami #2 Kurouchi features traditional carbon steel, a black forged finish, and a walnut octagonal handle.

    Its appearance is simple, powerful, and unmistakably Japanese.

    I previously wrote an article explaining which knife I would choose if I could use only one knife in my professional kitchen.

    My answer was a Kiritsuke.

    That is how highly I regard its versatility.

    In my daily work at a sushi counter, I need a knife that can handle different ingredients and cutting tasks efficiently.

    The pointed tip of a Kiritsuke is useful for precise work, while the blade can handle many everyday preparation tasks.

    Of course, no single knife is perfect for absolutely everything.

    However, I have always appreciated knives that allow me to work comfortably without constantly changing tools.

    Although I particularly recommend this knife for professional chefs, I would also be delighted to see home cooks enjoying it.

    For anyone who finds 180mm slightly too long, we also offer a 165mm version.

    The shorter blade may feel more comfortable for someone who prefers a compact knife.

    Because this knife uses Aogami #2 carbon steel, it requires proper cleaning, drying, and maintenance.

    The black Kurouchi finish gives it a beautiful traditional appearance, but it does not eliminate the need to care for the exposed carbon steel.

    For someone who appreciates traditional Japanese knives, however, that responsibility can become part of the enjoyment of ownership.

    I have written more about my personal preference for this knife shape in Kiritsuke — The Knife I Would Choose If I Could Own Only One.

    For an experienced cook or professional chef, I believe this would be a particularly memorable Christmas gift.

    Which Japanese Knife Christmas Gift Would I Personally Choose?

    After introducing these five recommendations, you might be wondering which one I would personally choose.

    The answer depends entirely on the person receiving the gift.

    If I were choosing a knife for someone who had never owned a Japanese knife before, I would probably start with the VG10N Damascus Santoku or the VG10 hammered Damascus series.

    Both offer beautiful designs, practical blade shapes, and relatively straightforward maintenance.

    For someone who appreciates traditional Japanese craftsmanship, I would strongly consider the Ginsan Nashiji series.

    Its appearance is beautifully Japanese, and its stainless steel blade makes it a practical choice for everyday use.

    For an experienced cook who enjoys traditional carbon steel, the Aogami #2 Santoku or Kurouchi Kiritsuke would be particularly appealing.

    Personally, I have always believed that choosing a knife should begin with understanding how it will be used.

    A professional chef and someone who cooks occasionally at home may have completely different requirements.

    Even two professional chefs can have very different preferences.

    That is why I do not believe there is one perfect knife for everyone.

    The best Japanese Knife Christmas Gift is not necessarily the most expensive knife or the one with the most elaborate design.

    It is the knife that suits the person receiving it.

    After more than 25 years working in professional kitchens, that is still one of the most important lessons I would share.

    Christmas Sale Begins Wednesday, 14 October 2026!

    Our limited-time Christmas Sale officially begins at 12:00 AM on Wednesday, 14 October 2026 (Queensland time).

    This is a wonderful opportunity to discover our carefully selected range of authentic Japanese knives.

    Some of the knives featured in today’s article are available in very limited quantities.

    In particular, our VG10N 33 Layer Damascus Rainbow Spacer series currently has only one knife available in each colour.

    Once these knives are sold, we cannot guarantee when the same models will become available again.

    If you are considering a Japanese knife as a Christmas present this year, I encourage you to explore our collection before the sale begins.

    At Asaoya Yaichi, we carefully select Japanese knives that we believe offer genuine quality, beautiful craftsmanship, and lasting value.

    Whether you are purchasing your first Japanese knife, choosing a present for someone special, or adding another knife to your own collection, I hope you find something that brings enjoyment to your kitchen.

    A carefully chosen Japanese knife can become much more than a Christmas present.

    It can become a trusted kitchen companion for many years to come.

  • Choosing Your First Japanese Knife: 5 Essential Lessons from a Chef

    Choosing Your First Japanese Knife: 5 Essential Lessons from a Chef

    Ishizuchi Kanamono Manufactory

    Choosing your first Japanese knife can be confusing. There are so many steels, shapes, sizes, brands and price ranges that it is easy to spend hours researching and still not know what to buy.

    So let me make my answer simple.

    If you are buying your first Japanese knife for general home cooking, I would start by looking at a 180mm Santoku or a 210mm Gyuto, preferably in an easy-to-maintain stainless steel such as VG10 or Ginsan.

    That does not mean these are the “best” Japanese knives. It means they are practical places to start.

    Interestingly, more than 25 years ago, my own first Japanese knives were quite similar to what I would still recommend today.

    If you are looking for Japanese knives in Australia, you can also explore our current range here:

    Choosing Your First Japanese Knife: My Own First Choice


    210mm Gyuto VG10 Polished Hammered 67 Layer Damascus Green Handle

    135mm Petty VG10 Polished Hammered 67 Layer Damascus Green Handle

    The first Japanese knives I bought for myself were a 210mm Damascus Gyuto and a Petty knife from the same series. If I remember correctly, the steel was probably VG10.

    At the time, I certainly did not understand knife steels the way I do now. I was not comparing every specification or thinking deeply about hardness, edge retention or steel composition.

    I simply bought knives that I wanted to use.

    Looking back after more than 25 years in professional kitchens, however, I think the basic combination actually made a lot of sense.

    A 210mm Gyuto can handle meat, fish and vegetables. The Petty takes care of smaller and more detailed jobs. Between those two knives, you can handle a huge amount of everyday kitchen work.

    👉 INTERNAL LINK: 探究 Tankyū | What Does VG10 Actually Mean?

    Should Your First Japanese Knife Be a Gyuto or Santoku?


    210mm Gyuto Ginsan Nashiji Forged Magnolia Octagonal Handle Buffalo Horn Ferrule

    180mm Santoku Ginsan Nashiji Forged Magnolia Octagonal Handle Buffalo Horn

    For someone choosing their first Japanese knife, this is probably one of the most useful questions to answer.

    If you have enough bench space and are comfortable with a slightly longer blade, I think a 210mm Gyuto is an excellent starting point. The extra blade length becomes especially useful when cutting larger pieces of meat, fish or vegetables, because you can use a longer cutting stroke.

    👉 INTERNAL LINK: [Gyuto vs Santoku — Which Japanese Knife Is Right for You?]

    For a smaller home kitchen, or if 210mm simply feels too large, I would look at a 180mm Santoku.

    A Santoku is compact, comfortable and capable of handling meat, fish and vegetables. For many home cooks, it may be all the knife they really need.

    Neither one is automatically better.

    The question is which one makes more sense in your kitchen.

    Choosing Your First Japanese Knife Steel


    180mm Santoku Aogami #2 Green Micarta Handle with Turquoise Spacer

    165mm Santoku A10 Damascus Black & Red Octagonal Handle

    180mm Santoku SG2 Rosewood Octagonal Handle

    Steel names can make buying a Japanese knife unnecessarily intimidating.

    VG10, Ginsan, Blue #2, Blue Super, SG2 — the list goes on.

    For a beginner, I would not start by asking which steel can become the sharpest.

    I would ask: How much maintenance do you want?

    For many first-time buyers, VG10 or Ginsan makes a lot of sense. Both offer excellent performance while being stainless and relatively easy to live with.

    👉 INTERNAL LINK: [Japanese Knife Steel — Understanding the Different Steels Used in Japanese Knives]

    I personally enjoy carbon steels such as Blue #2, especially for certain cutting jobs. But carbon steel requires more attention to moisture and maintenance.

    That does not make it unsuitable for beginners. It simply means you should understand what you are buying.

    Choosing Your First Japanese Knife Does Not Mean Buying the Most Expensive One


    240mm Sujihiki VG10 Hammered 17 Layer Damascus Mahogany

    There is another reason I do not think beginners should become too obsessed with specifications or prestige.

    Years ago, I took one of my knives back to a knife shop to have it sharpened.

    The person there almost laughed at it.

    I still remember that experience.

    Maybe, from his perspective, it was not a particularly special knife. But I had bought it, used it professionally and relied on it to do my job.

    That experience taught me something I still believe today.

    A knife does not need to impress another knife enthusiast. It needs to work for the person holding it.

    After more than 25 years as a chef, I have used carbon steel, stainless steel, Yanagiba, Gyuto, Sujihiki and many other knives. Today, one of the knives I use most at the sushi counter is a VG10 Sujihiki.

    Not because VG10 is the most prestigious steel.

    It simply works for what I do.

    What About a Petty as Your Second Japanese Knife?


    120mm Petty Ginsan Nashiji Forged Magnolia Octagonal Handle Buffalo Horn Ferrule

    Once you have your main knife, my next choice would probably be a Petty.

    A Petty around 120–135mm is useful for smaller ingredients and detailed preparation where a 180mm or 210mm knife feels unnecessarily large.

    Interestingly, this is also what I did with my first Japanese knives: a Gyuto and a Petty.

    I did not understand it this way at the time, but looking back, they complemented each other extremely well.

    My Advice for Choosing Your First Japanese Knife

    After more than 25 years in professional kitchens, my advice is actually simpler than it would have been when I was younger.

    For general home cooking, start with a 180mm Santoku or 210mm Gyuto.

    If you want easy maintenance, look seriously at VG10 or Ginsan.

    Then, if you want a second knife, consider a 120–135mm Petty.

    If you mainly prepare vegetables, a Nakiri may make more sense. If you regularly slice fish or meat in long clean strokes, you may eventually want to explore a Sujihiki.

    But you do not need to start there.

    When choosing your first Japanese knife, do not worry too much about owning the knife with the highest hardness, the most expensive steel or the most impressive specifications.

    Start with a knife that fits your kitchen and the food you actually cook.

    More than 25 years after buying my first 210mm Gyuto and Petty, that is still where I would begin.

  • Carbon Steel Japanese Knives: 5 Powerful Lessons from My Real Experience

    Carbon Steel Japanese Knives: 5 Powerful Lessons from My Real Experience


    180mm Santoku Aogami #2 Green Micarta Handle with Turquoise Spacer

    Carbon Steel Japanese Knives are often described as difficult to maintain. They can rust, they react with certain foods, and compared with stainless steel, they certainly require a little more attention.

    But after more than 25 years working as a professional chef, I don’t think carbon steel knives are as difficult to live with as many people imagine.

    I currently use Aogami Super, Aogami #2 and VG10 knives in my daily work, and my experience with each one has been quite different. For me, the important thing is not trying to find a completely maintenance-free knife. It is understanding the steel you are using and learning how to look after it.

    If you are looking for Japanese knives in Australia, you can also explore our collection here:

    👉 https://asaoyayaichi.com.au

    Carbon Steel Japanese Knives Can Rust — But That Is Not the Whole Story

    Ishizuchi Kanamono Manufactory

    There is no point pretending otherwise: Carbon Steel Japanese Knives can rust faster than stainless steel.

    I also feel that once a carbon steel knife has developed rust, that particular knife can sometimes seem more likely to rust again.

    However, that does not mean carbon steel is constantly difficult to maintain.

    One knife I currently use regularly is an Aogami Super （青紙スーパー）sujihiki. I use it for fish, meat and vegetables, and sometimes even acidic ingredients such as lemons and limes.

    My routine is extremely simple.

    After using it, I wash it with water and immediately wipe it dry with a towel.

    That’s basically it.

    Despite using it constantly, rust has not been a major problem.

    Perhaps the fact that I use this knife almost every day helps. It is regularly being used, washed, dried and checked rather than being left somewhere for weeks. I cannot say that daily use itself prevents rust, but in my experience, regular care makes carbon steel much easier to manage.

    👉 INTERNAL LINK: Japanese Knife Patina article

    Understanding the difference between normal patina and harmful rust is also important when living with carbon steel.

    My Aogami #2 Knife Is a Different Story


    180mm Kiritsuke Aogami #2 Kurouchi Walnut Octagonal Handle

    My Aogami #2 kurouchi gyuto behaves differently.

    This knife has rusted before, and since then I have found that if I use it, wipe away the moisture and simply leave it for a long period, rust can return.

    So I treat this knife differently.

    When necessary, I deal with the rust through sharpening and use Sabitoru to remove surface rust. If I know I will not use the knife for a while, I apply a thin layer of camellia oil before storing it.

    👉 INTERNAL LINK: Sabitoru Fine article

    Sabitoru has become a useful part of my maintenance routine when small areas of rust appear.

    👉 INTERNAL LINK: Camellia Oil article

    Camellia oil is another simple option when storing carbon steel knives for longer periods.

    This is why I don’t believe owning Carbon Steel Japanese Knives needs to be stressful. Once you have a basic maintenance kit and understand what your knife needs, caring for it becomes part of owning and using the knife.

    Carbon Steel Japanese Knives vs VG10 in Daily Use


    240mm Sujihiki VG10 Hammered 17 Layer Damascus Mahogany

    The VG10 sujihiki I currently use is completely different when it comes to rust.

    Honestly, rust is something I barely think about with this knife.

    But I still treat it almost exactly the same way as my carbon steel knives.

    Use it. Wash it. Dry it.

    That’s all.

    Stainless steel gives you considerably more freedom when it comes to corrosion resistance, but I still don’t believe that means you should leave a good knife wet or dirty.

    There is also another side to stainless steel maintenance that I have noticed during my career.

    Because stainless steel is so easy to live with, it can be tempting to keep using the knife without sharpening it until it becomes seriously dull.

    That can create another problem.

    A Rust-Resistant Knife Is Not a Maintenance-Free Knife


    135mm Petty VG10 Polished Hammered 67 Layer Damascus Green Handle

    In my experience, when some stainless steels become extremely dull, bringing the edge back can feel harder than maintaining the knife regularly.

    This is where people can make a mistake.

    When a knife is not getting sharp quickly enough, there is a temptation to raise the sharpening angle and concentrate only on creating a sharp edge.

    You may get an edge again, but over time the geometry behind that edge can become thicker. Eventually, the knife may feel sharp at the very edge but still struggle to move smoothly through food.

    This connects directly with something I recently wrote about: knife thinning.

    👉 INTERNAL LINK: Japanese Knife Thinning article

    Thinning is not simply about making the edge sharp. It is about maintaining the geometry behind the cutting edge so the knife can continue cutting the way it should.

    That is why regular maintenance matters whether your knife is carbon steel or stainless steel.

    Are Carbon Steel Japanese Knives Really Difficult?


    210mm Sujihiki Aogami #2 Kurouchi Magnolia Handle

    After using different steels professionally, my answer is no.

    Carbon steel requires more awareness of moisture and rust. Stainless steel such as VG10 makes that part much easier.

    But neither should be neglected.

    For me, Carbon Steel Japanese Knives are not difficult knives. They are knives that you need to understand and learn how to live with.

    Wash them after use. Dry them properly. Deal with rust early if it appears. Use camellia oil when storing carbon steel for longer periods. And don’t wait until any knife becomes completely dull before thinking about sharpening.

    That small amount of care can make a very big difference.

    For anyone exploring Japanese Knives Australia, I believe the question should not simply be, “Which steel is best?”

    A better question is:

    Which steel suits the way I cook, sharpen and care for my knives?

    There is no single steel that is perfect for everyone. Understanding how you actually use your knife is far more important than simply choosing carbon steel or stainless steel.

    Nakiri vs Santoku: 3 Essential Lessons from My Kitchen


    165mm Nakiri Ginsan Nashiji Forged Magnolia Octagonal Handle Buffalo Horn Ferrule

    Nakiri vs Santoku is a comparison I think about differently after more than 25 years as a professional chef. Both cut vegetables. I notice the difference when I want a straight line or turn a daikon for katsuramuki. Then the edge shape becomes something I can feel. The same vegetable can make two knives feel surprisingly different in my hands when the goal is a precise shape rather than speed.

    If you are looking at Japanese knives in Australia, you can explore the knives I have selected for Asaoya Yaichi here: https://asaoyayaichi.com.au. Before choosing a shape, I would think about the work you actually do on your cutting board.

    Nakiri vs Santoku: Straight Cuts on the Board


    180mm Santoku Ginsan Nashiji Forged Magnolia Octagonal Handle Buffalo Horn

    When I cut a vegetable into neat rectangular strips, a nakiri’s relatively straight edge gives me a clear line to follow. I can use a controlled push cut and watch where the edge meets the board. With short, rectangular pieces, even a slight change in the direction of a cut is easy to see. I find myself paying attention to the line all the way through the vegetable.

    A santoku can certainly make the same cuts. I have used santoku knives for vegetable preparation throughout my career. But some curve more toward the tip, and I may adjust my motion to keep a series of cuts consistent.

    The knife does not make the strips straight by itself. My preparation, grip, sharpening and cutting technique matter too. Still, that straight edge is why I might choose a nakiri when a tidy result matters.

    👉 Read my beginner’s guide to choosing a Japanese knife.⁠

    Blade thickness also changes how a knife moves through a vegetable. A straight outline alone cannot tell me whether a particular knife will feel good in use.

    👉 See what I learned about Japanese knife thickness.⁠

    Katsuramuki Makes Me Notice the Blade Shape

    Nakiri vs Santoku for Katsuramuki


    165mm Usuba A8 Hammered Damascus Black & Red Octagonal Handle

    Katsuramuki means turning a vegetable, often a daikon, while peeling off a long, thin sheet. I watch the edge, turn the vegetable and try to keep an even thickness. It demands control.

    In my experience, the straighter edge of a nakiri is easier to follow during this work. When I use a more curved section of a santoku, the peel can start to wander or curve away from the line I want. That is the practical difference I feel. Once a long peel starts moving away from my intended line, correcting it without breaking the sheet becomes difficult. A santoku can still do katsuramuki.

    In fact, the straighter section near the heel of some santoku knives can also be used for peeling. The result depends on the individual knife and the way it is handled. For traditional, highly refined vegetable work, a single-bevel usuba is another specialised choice. A nakiri is generally double bevel, so I would not present it as a substitute for every technique an usuba is designed to perform.

    👉 Read my guide to single and double bevel Japanese knives.⁠

    Nakiri vs Santoku When There Is Room for Only One


    180mm Santoku Aogami #2 Green Micarta Handle with Turquoise Spacer

    The straight edge has a real purpose, but a kitchen does not consist of daikon and rectangular vegetable cuts alone. I might prepare onions and greens, then portion boneless meat or fish for the same meal. A santoku makes sense for that changing workload. Its pointed tip helps with some detail work, while the blade moves between ingredients.

    If someone in Australia asked me to recommend just one Japanese knife for everyday home cooking, I would usually start by discussing a santoku or a gyuto. The choice depends on board space, ingredients and cutting style. A nakiri becomes more interesting when vegetable preparation is a regular part of their cooking and they value the way its straight edge behaves.

    👉 Read my Santoku vs Gyuto comparison for another everyday-knife decision.⁠

    I notice the nakiri’s advantage when making straight strips or holding a line during katsuramuki. Someone preparing a wide range of meals may value the santoku’s flexibility more. The name of the knife alone cannot tell me which one belongs in a particular kitchen. I also consider the actual blade, its weight and the person holding it.

    That is how I would choose between them: by the cut in front of me, not by a label on the knife. If you are still weighing up different shapes, I have written more about the knives I would choose for Australian kitchens.

  • Japanese Knife Terms: 5 Fascinating Words I Didn’t Know After 25 Years as a Chef

    Japanese Knife Terms: 5 Fascinating Words I Didn’t Know After 25 Years as a Chef

    Ishizuchi Kanamono Manufactory

    I have worked as a professional chef for more than 25 years, and Japanese knives have been part of my working life for a long time. But since starting Asaoya Yaichi and learning more about how Japanese knives are actually made, I have realised something interesting: there are many Japanese knife terms that I simply did not know.

    Using a knife every day and understanding how a blacksmith constructs one are two very different things.

    So I decided to research some of these words myself. This is not a glossary written from the perspective of a blacksmith. It is a chef learning more about the tools he has used for decades — and sharing what he discovers along the way.

    If you are looking for Japanese knives in Australia while reading this story, you can also visit our collection here.

    👉 Visit Asaoya Yaichi: https://asaoyayaichi.com.au

    For the first part of this series, I chose five Japanese knife terms that are closely connected: Hagane, Jigane, Awase, San-mai and Warikomi.

    Japanese Knife Terms #1: What Does Hagane Mean?


    180mm Santoku Aogami #2 Green Micarta Handle with Turquoise Spacer

    Hagane (鋼) means steel, but in discussions about laminated Japanese knives it commonly refers to the harder steel that forms the cutting edge.

    This was interesting to me because, as a chef, I have normally thought about steel by names such as Aogami #2, Ginsan, VG10 or SG2. I thought about how the knife sharpened, how long the edge lasted and how it behaved during service.

    Hagane approaches the subject from a different direction. It describes the role that hard steel plays within the construction of a laminated blade.

    That made me look at familiar knives differently.

    👉 INTERNAL LINK: Read my article about choosing Japanese knife steel after 25 years in professional kitchens.

    Japanese Knife Terms #2: What Is Jigane?


    210mm Gyuto Ginsan Nashiji Forged Magnolia Octagonal Handle Buffalo Horn Ferrule

    Jigane (地金 / 地鉄) was another term I had seen without really stopping to understand it.

    In traditional laminated knife construction, jigane refers to the softer material supporting the harder hagane. Depending on the construction, this can be soft iron, mild steel or another softer cladding material.

    The concept is surprisingly practical: the hard steel performs at the cutting edge, while the softer material supports it.

    Once I understood this, some of the visual characteristics of traditional Japanese knives also started to make more sense.

    👉 INTERNAL LINK: Read my guide to Japanese knife finishes, including Nashiji, Kurouchi, Damascus and Mirror finishes.

    Understanding Awase as a Japanese Knife Term


    180mm Santoku VG10N 33 Layer Damascus Green Marble Handle Rainbow Spacer Orange

    Awase (合わせ) broadly describes a laminated or joined construction in which different materials are combined rather than making the blade from one homogeneous piece of steel.

    This was one of those Japanese knife terms that helped several other words suddenly connect.

    Hagane and jigane are not simply two unrelated materials. In an awase knife, they work together as part of the blade’s construction.

    That also helped me better understand why hand-forging should not simply be reduced to the image of someone hitting hot steel with a hammer. The construction itself matters.

    👉 INTERNAL LINK: Read “Hand-Forged vs Machine-Made Japanese Knives” for more about how Japanese knives are produced.

    Japanese Knife Terms: San-mai and Warikomi Are Not Exactly the Same

    Japanese Knives Australia

    This is where the terminology became particularly interesting to me.

    San-mai (三枚) literally refers to three layers. In a typical double-bevel construction, harder hagane forms the core, with softer cladding on either side.

    Warikomi (割込) uses a different construction method. The softer body is split or opened and the harder steel is inserted into it.

    I had previously seen these words in knife descriptions without giving much thought to why both existed. Researching them showed me that words that may look like technical marketing language can actually describe meaningful differences in how a blade is constructed.

    👉 INTERNAL LINK: Read my article about Tosa knife history and how Japanese blade-making developed from traditional craftsmanship.

    Why Japanese Knife Terms Matter When Buying Japanese Knives in Australia


    180mm Kiritsuke Aogami #2 Kurouchi Walnut Octagonal Handle

    Do you need to memorise Hagane, Jigane, Awase, San-mai and Warikomi before buying a good kitchen knife?

    No.

    I spent more than 25 years working in professional kitchens without knowing every one of these terms.

    But now that I sell Japanese knives in Australia, I want to understand more than just how a knife feels on the cutting board. I want to understand why it was made that way, what the maker was trying to achieve and what the terminology in a product description actually means.

    For me, learning these Japanese knife terms has become another part of understanding Japanese knives themselves.

    And if you are currently comparing Japanese Knives Australia, terminology should not replace practical considerations such as what you cook, blade length, steel, maintenance and how the knife feels in use. It simply gives you another layer of knowledge when making that decision.

    👉 INTERNAL LINK: Read “Japanese Knives Australia: 5 Powerful Choices I Would Make After 25 Years as a Professional Chef.”

    There are still plenty of Japanese knife terms I do not know — Shinogi, Kireha, Urasuki, Koba and many others deserve a closer look.

    So rather than pretending I already know them all, I am going to keep researching them.

    That will be Part 2.

  • Japanese Knife Steel: 5 Powerful Lessons I Learned After 25 Years as a Chef

    Japanese Knife Steel: 5 Powerful Lessons I Learned After 25 Years as a Chef

    Ishizuchi Kanamono Manufactory

    For most of my 25 years working as a professional chef, I honestly did not care much about Japanese knife steel.

    I knew my knives felt different, but I rarely thought about the reason. Some held their edge longer. Some could lose their initial sharpness but still somehow get me through a busy service. Others became frustrating once the edge started to fade. Some were easy to sharpen, while others required more patience. And, of course, some rusted much more easily than others.

    I noticed all of these differences long before I understood the steels behind them.

    It was only after starting Asaoya Yaichi and learning more seriously about Japanese knives that those years of experience began to connect with what I was learning about steel.

    If you are looking for Japanese knives in Australia, understanding these differences can make choosing your next knife much easier.

    👉 Visit the Asaoya Yaichi online store to explore our Japanese knives in Australia.

    Japanese Knife Steel Was Never My Priority in the Kitchen


    165mm Santoku A10 Damascus Black & Red Octagonal Handle

    As a working chef, I was interested in practical results.

    Does it cut well? How long can I use it before sharpening? Can I keep using it when the edge starts to fade? How quickly can I bring the edge back?

    I did not stand in the kitchen thinking about carbon percentages or steel specifications.

    Looking back, however, I realise I had been learning about Japanese knife steel through my hands for years without knowing it.

    👉 INTERNAL LINK: Hand-Forged vs Machine-Made Knives

    Learning more about knife making also taught me that steel is only part of the story. Heat treatment, blade geometry, sharpening and construction all influence how a knife performs.

    Learning Japanese Knife Steel Finally Explained My Preferences


    180mm Santoku Aogami #2 Green Micarta Handle with Turquoise Spacer

    Once I started selling Japanese knives, I needed to understand what I was actually selling.

    That changed the way I looked at my own knives.

    Suddenly, experiences from many years in professional kitchens started making sense. Today I know that I personally enjoy using Aogami #2 and Aogami Super. They suit the way I work and, importantly, the way I sharpen.

    That does not mean I believe they are the best steels for everyone.

    👉 INTERNAL LINK: Is an Expensive Japanese Knife Really Worth It?

    Specifications and price can tell us something about a knife, but they cannot completely describe what it will feel like after months or years of real kitchen use.

    Choosing Japanese Knife Steel for Japanese Knives in Australia


    210mm Gyuto Ginsan Nashiji Forged Magnolia Octagonal Handle Buffalo Horn Ferrule

    This becomes particularly important when choosing Japanese knives in Australia.

    As a professional chef, I use my knives constantly. With carbon steel, I wash the blade, dry it and continue using it regularly. Patina develops, but personally I have not found rust particularly difficult to manage during everyday professional use.

    Home use can be very different.

    You might use a carbon-steel knife tonight and then not touch it again for several days. If moisture remains on the blade during that time, rust can appear surprisingly quickly.

    That is one reason stainless steels such as VG10 or Ginsan can make a lot of sense for people who want a Japanese knife without constantly thinking about maintenance.

    👉 INTERNAL LINK: Japanese Knife Rust Removal: 5 Powerful Reasons I Keep a Sabitoru Fine in My Knife Kit

    Stainless does not mean completely rust-proof, but it is generally more forgiving.

    This is also why there is no single answer when someone asks me which steel they should choose.

    Japanese Knife Steel and What I Feel at the Sharpening Stone


    180mm Kiritsuke Aogami #2 Kurouchi Walnut Octagonal Handle

    There is another difference I have noticed over the years: sharpening.

    This is my personal experience rather than a rule for every knife, but when some stainless knives become very dull, I find they can become frustrating.

    I can usually bring them back to a reasonably sharp edge without too much trouble. But getting that edge back to the extremely sharp condition I personally want can sometimes require patience.

    With Aogami carbon steels, I often feel that I can bring the edge back more naturally.

    Of course, this depends on much more than simply whether a knife is carbon or stainless. Hardness, heat treatment, blade geometry and sharpening stones all matter.

    That is why I prefer talking about what I have actually experienced rather than saying one steel is universally better.

    Japanese Knives Australia: Steel Is Only the Beginning


    165mm Usuba A8 Hammered Damascus Black & Red Octagonal Handle

    If you are searching for Japanese knives in Australia, I would not start by asking, “What is the best steel?”

    I would start with different questions.

    How often do you cook? Do you sharpen your own knives? Are you comfortable drying a carbon-steel blade immediately after use? Do you want something easy to maintain? What shape and length actually suit the food you prepare?

    Understanding Japanese knife steel helps answer those questions, but steel should not become the only reason you choose a knife.

    I recently wrote about the Japanese knives I would personally choose after more than 25 years in professional kitchens. That article looks beyond steel and considers the complete knife from the perspective of actual use.

    👉 IMPORTANT INTERNAL LINK: Japanese Knives Australia: 5 Powerful Choices I Would Make After 25 Years as a Professional Chef

    For me, that is the real value of finally learning about steel.

    Twenty-five years ago, I could tell you whether I liked a knife. I just could not always explain why.

    Today, I understand much better why Aogami #2 and Aogami Super suit me, why stainless steel can be a better choice for many people, and why the most impressive steel name does not automatically make the best knife for the person holding it.

    If you are choosing Japanese knives in Australia, learn about the steel—but choose the knife according to the way you actually cook.

  • Japanese Knives Australia Ranking: 5 Exceptional Knives I Would Choose After 25 Years as a Chef

    Japanese Knives Australia Ranking: 5 Exceptional Knives I Would Choose After 25 Years as a Chef

    Asaoya Yaichi

    Choosing a Japanese knife is highly personal. Steel, balance, blade shape, handle design and even appearance can completely change how a knife feels in your hand. After more than 25 years working in professional kitchens, I have learned that the knife I personally want is not always the most expensive one.

    That is why I wanted to create my own Japanese Knives Australia Ranking. Rather than ranking knives purely by price or specifications, these are five knives from the Asaoya Yaichi collection that stand out to me through a combination of usability, craftsmanship, steel, rarity and character.

    If you are currently looking for Japanese knives in Australia, you can also see our collection here:

    Japanese Knives Australia Ranking — Why These 5?

    Ishizuchi Kanamono Manufactory

    There are many excellent Japanese knives available today, so this ranking is deliberately personal. I am looking at these knives from the perspective of someone who has spent decades actually using knives in professional kitchens.

    Some knives impress me because of their practicality. Others because of traditional Japanese craftsmanship. And sometimes there is simply a knife that makes you think, “I want that one.”

    👉 INTERNAL LINK: Read “Is an Expensive Japanese Knife Really Worth It?” here.

    No. 5 — 210mm Gyuto VG10 Polished Hammered 67 Layer Damascus Green Handle


    210mm Gyuto VG10 Polished Hammered 67 Layer Damascus Green Handle

    At number five in my Japanese Knives Australia Ranking is a 210mm Gyuto made from VG10 stainless steel with a polished hammered 67-layer Damascus finish.

    This is what I would call a dependable all-rounder. A 210mm Gyuto is extremely versatile in both professional and home kitchens, while VG10 offers a practical combination of edge retention, corrosion resistance and ease of maintenance.

    The Damascus pattern and green handle also make this knife visually impressive without sacrificing everyday usability.

    Personally, I would be very tempted to purchase this Gyuto together with the matching Petty. As a set, they cover an enormous amount of everyday kitchen work while looking fantastic together.

    👉 INTERNAL LINK: Read “Hand-Forged vs Machine-Made Japanese Knives” here.

    No. 4 — 180mm Santoku VG10N 33 Layer Damascus Green Marble Handle Rainbow Spacer


    180mm Santoku VG10N 33 Layer Damascus Green Marble Handle Rainbow Spacer Orange

    Number four is something quite different.

    This 180mm Santoku combines VG10N steel with 33-layer Damascus, a Green Marble handle and a Rainbow Spacer.

    The marble-style handle immediately catches the eye, but what makes this knife particularly interesting to me is its rarity. Japanese knives with this combination of blade and handle design are not something you see everywhere.

    The 180mm Santoku size is also highly practical. It gives you enough blade for serious preparation while remaining comfortable and controllable for everyday cooking.

    For someone wanting a Japanese knife that feels genuinely different from the usual choices, this is a special piece.

    👉 INTERNAL LINK: Read “Most Popular Japanese Knife Souvenirs” here.

    No. 3 — 180mm Kiritsuke Aogami #2 Kurouchi Walnut Octagonal Handle


    180mm Kiritsuke Aogami #2 Kurouchi Walnut Octagonal Handle

    If I ranked these knives purely on usability, this could easily be number one.

    I have written about this knife before because I genuinely think its shape is exceptionally easy to use. The Aogami #2 carbon steel is also a steel I personally enjoy working with.

    But what gives this knife its character is the Kurouchi finish.

    The dark, rustic surface carries the character I associate with traditional Tosa knives. It does not try to look overly polished or perfect. For people who understand Japanese knives, that simplicity is part of the attraction.

    This knife is also currently available to see at Chanoyu cafe on the Gold Coast.

    👉 INTERNAL LINK: Read my article about the 180mm Kiritsuke Aogami #2 here.

    No. 2 — Gyuto Ginsan Nashiji Forged Magnolia Octagonal Handle Buffalo Horn Ferrule


    Gyuto Ginsan Nashiji Forged Magnolia Octagonal Handle Buffalo Horn Ferrule

    Number two in my Japanese Knives Australia Ranking is our Ginsan Nashiji Gyuto.

    This knife represents something very different from the modern Damascus designs above. Quality Ginsan stainless steel, a Nashiji finish, forged construction, Magnolia octagonal handle and Buffalo Horn ferrule come together in a knife that feels unmistakably Japanese.

    Interestingly, when I take our knives to businesses and show them in person, this Ginsan series consistently attracts attention. Many of the people I speak with immediately want to know more about it.

    We also carry this style in Gyuto, Santoku, Petty and Nakiri, making it particularly attractive for someone who wants to build a matching Japanese knife set rather than purchase just one knife.

    👉 INTERNAL LINK: Read our article about Ginsan steel and Nashiji-finished Japanese knives here.

    No. 1 — 180mm Santoku Aogami #2 Green Micarta Handle with Turquoise Spacer


    180mm Santoku Aogami #2 Green Micarta Handle with Turquoise Spacer

    My number one choice is the 180mm Santoku Aogami #2 with Green Micarta Handle and Turquoise Spacer.

    I have featured this knife before, and my opinion has not changed.

    For me, it is simply the coolest knife in the collection.

    The turquoise band running through the handle immediately catches the eye, while Aogami #2 is one of my favourite steels. What I particularly like is the contrast between these elements.

    Aogami #2 represents a very traditional Japanese carbon steel, yet the Green Micarta and turquoise give the knife a modern personality. At the same time, the polished blade still retains a subtle, restrained character that reminds me of Japanese wabi-sabi rather than excessive decoration.

    It is traditional and contemporary at the same time.

    After more than 25 years working with kitchen knives, I have handled plenty of expensive and impressive blades. But if I were choosing one knife from the Asaoya Yaichi collection for myself, this is the one I would want.

    That is why it takes first place in my Japanese Knives Australia Ranking.

    👉 INTERNAL LINK: Read my previous article featuring the Aogami #2 Santoku with Green Micarta and Turquoise Spacer here.

    Final Thoughts on My Japanese Knives Australia Ranking

    This is not a ranking based simply on price. It reflects what I personally value after more than 25 years in professional kitchens: usability, steel, craftsmanship, individuality and the feeling a knife gives you when you pick it up.

    Your number one may be completely different from mine — and that is part of what makes Japanese knives so interesting.

    A knife is a tool, but a good knife can also become something personal. Among these five, there are knives I admire, knives I would recommend for their practicality and knives I simply want to own.

    And sometimes, that final feeling matters most.

  • Japanese Knives Australia: 5 Powerful Choices I Would Make After 25 Years as a Professional Chef

    Japanese Knives Australia: 5 Powerful Choices I Would Make After 25 Years as a Professional Chef

    Asaoya Yaichi

    When people search for Japanese Knives Australia, they are often faced with an enormous choice of steels, shapes, finishes and prices. After more than 25 years working in professional kitchens in Japan and Australia, I look at knives a little differently. I am less interested in what sounds impressive on paper and more interested in what I would actually want beside me during a long day in the kitchen.

    If you are looking for Japanese knives in Australia, you can also explore the current Asaoya Yaichi collection here:

    👉 Visit our online store:
    https://asaoyayaichi.com.au

    For me, a good knife collection should not simply look beautiful. Each knife should have a purpose, feel comfortable in the hand and be something I genuinely want to use.

    Japanese Knives Australia: My First Choice Would Be Ginsan Nashiji


    Ginsan Nashiji Forged Magnolia Octagonal Handle Buffalo Horn

    If I were building a professional set from the current Asaoya Yaichi range, I would seriously consider starting with Ginsan steel with a Nashiji finish.

    Ideally, I would like a Gyuto, Petty, Nakiri and Santoku in this combination.

    Ginsan, also known as Silver #3, offers an excellent balance for professional work. I like the idea of having the performance and sharpening characteristics associated with a quality Japanese knife while gaining the practical advantage of stainless steel.

    The Nashiji finish is another reason I like this combination. Its subtle, textured appearance has character without being overly decorative. For me, these are knives that can look beautiful while still feeling like serious working tools.

    👉 INTERNAL LINK: Add a link here to the existing Ginsan steel article.

    The Nashiji finish itself also has an interesting place in Japanese knife making.

    Japanese Knives Australia and the Practical Appeal of VG10


    VG10 Polished Hammered 67 Layer Damascus Green Handle

    Another set I would be very comfortable using is our VG10 series with green handles.

    A Gyuto, Petty and Santoku would already cover a huge amount of everyday kitchen work. VG10 is familiar to many people looking for Japanese knives in Australia, and from my experience, a properly sharpened VG10 knife can perform extremely well.

    I currently use a VG10 Sujihiki myself, and that experience is part of why I do not judge a knife only by the reputation or price of its steel. Sharpening, geometry and how the knife is actually used matter enormously.

    👉 INTERNAL LINK: Add a link here to Monozukuri | Where Japanese Craftsmanship Meets Quiet Beauty

    My Personal Choice: Aogami #2 with Turquoise


    180mm Santoku Aogami #2 Green Micarta Handle with Turquoise Spacer

    Then there is the choice that is harder for me to ignore personally: Aogami #2 with a turquoise handle.

    I have used carbon steel extensively during my career, and I still have a particular appreciation for Aogami #2. It requires more care than stainless steel, but for someone comfortable maintaining carbon steel, it can be extremely rewarding.

    The turquoise detail also gives the knife a personality of its own. If I were choosing purely according to my own taste rather than trying to create the most practical matching set, this would be very difficult for me to leave behind.

    Carbon steel is not automatically the right choice for everyone, which is why understanding maintenance is important.

    The 180mm Kurouchi Kiritsuke Is Still Hard to Beat


    180mm Kiritsuke Aogami #2 Kurouchi Walnut Octagonal Handle

    Purely from the perspective of usability, I also keep coming back to the 180mm Kurouchi Kiritsuke.

    I have written about this knife before because the size and shape make sense to me as a chef. At 180mm, it is large enough to handle serious preparation while remaining compact and controllable.

    For someone exploring Japanese Knives Australia and wanting one versatile knife rather than immediately building a complete set, this style deserves consideration.

    Japanese Knives Australia: Building a More Complete Professional Range

    Ishizuchi Kanamono Manufactory

    Looking at the Asaoya Yaichi range as a professional chef, I think we already have a very strong foundation. Gyuto, Santoku, Petty and Nakiri give both professional chefs and home cooks plenty of practical choices across Ginsan, VG10 and carbon steels.

    But I do not consider the collection finished.

    One area I particularly want to expand is traditional Japanese slicing knives. Yanagiba and Takohiki are important knives for sashimi and specialised fish work, and these are areas where I would like Asaoya Yaichi to offer more choice in the future.

    My goal is not to build the biggest collection of Japanese knives in Australia simply for the sake of having more products. I would rather develop a carefully selected range of knives that I can look at after more than 25 years in professional kitchens and genuinely say: I would use these myself.

    That principle will continue to guide how Asaoya Yaichi grows.

    椿油 | Camellia Oil for Japanese Knives: 5 Essential Lessons From My Own Experience

    Asaoya Yaichi

    Camellia oil for Japanese knives is often recommended as a traditional way to help protect blades from rust, especially carbon steel knives. I have worked with Japanese knives throughout more than 25 years in professional kitchens, but surprisingly, camellia oil has never been something I used regularly.

    I had used it before, however, and one particular experience has stayed with me for years.

    Now that Asaoya Yaichi will soon be carrying Kurobara Hamono Tsubaki, a Japanese blade-care oil, it seemed like the right time to look again at what knife oil actually does, when it is useful, and what I learned from my own experience.

    Why Camellia Oil for Japanese Knives Has Been Used for So Long


    Ishizuchi Kanamono Manufactory 

    Japanese carbon steel knives can develop rust when moisture remains on the blade. This is simply part of owning reactive carbon steel. With normal daily use, washing and thoroughly drying the knife immediately after use is often the most important habit.

    However, a protective oil becomes particularly useful when a carbon steel knife will not be used for some time.

    A very thin film of oil creates an additional barrier between the steel and moisture in the surrounding environment. This is why knife oils have traditionally been associated not only with kitchen knives but also with Japanese swords, woodworking tools and other high-quality steel tools.

    👉 INTERNAL LINK: Tosa Knives and Kurouchi — Why the Black Finish Became So Common

    Kurouchi knives are a good example. Their dark forge scale may provide some protection to parts of the blade, but the exposed cutting edge is still reactive carbon steel and needs proper care.

    My Own Mistake With Camellia Oil for Japanese Knives


    240mm Sujihiki VG10 Hammered 17 Layer Damascus Mahogany

    Years ago, one of the restaurants where I worked kept camellia oil for knife maintenance. Because it was available, I occasionally used it, although it never became part of my normal knife-care routine.

    At one point, I applied the oil to a knife that I planned to store for a longer period.

    Then I forgot about it.

    When I eventually took the knife out again, the oil had become unpleasantly sticky. Instead of finding a beautifully protected blade covered with a light film of oil, I found a knife with a thick, tacky residue.

    That experience stayed in my mind.

    Importantly, I do not know the brand or exact composition of the oil I used at that time, so I cannot say that the problem was caused by camellia oil itself. It may have been the particular product, the amount I applied, the storage conditions, the length of storage, or a combination of these factors.

    What I can say is that it taught me a simple lesson: more oil does not necessarily mean better protection.

    👉 INTERNAL LINK: Japanese Knife Rust Removal: 5 Powerful Reasons I Keep a Sabitoru Fine in My Knife Kit

    That connects directly with another lesson from professional kitchens: preventing rust is much easier than removing it later.

    Camellia Oil for Japanese Knives Should Be a Thin Protective Layer


    About Tosa Knives

    Knife oil does not need to make the blade look wet.

    For storage, the goal is simply to leave a very thin and even protective film on a completely clean and dry blade. Applying excessive oil can create unnecessary mess and may attract dust or make the knife unpleasant to handle when it comes out of storage.

    This is particularly relevant for carbon steels such as Aogami #2 and other traditional Japanese steels.

    👉 INTERNAL LINK: Is an Expensive Japanese Knife Really Worth the Money?

    For a knife that is being used every day in a professional kitchen, careful washing and immediate drying may be more practical than constantly applying oil. For a knife that may sit unused for weeks or months, however, a protective oil makes much more sense.

    Why I Chose Kurobara Hamono Tsubaki


    180mm Santoku Ginsan Nashiji Forged Magnolia Octagonal Handle Buffalo Horn

    This time, I wanted a product specifically intended for blade maintenance rather than simply assuming that any bottle labelled camellia oil would be suitable.

    Kurobara Hamono Tsubaki is made in Japan specifically for the maintenance and storage of blades. Kurobara describes it as suitable for Japanese swords, high-quality blades, tools and kitchen knives, and as a non-drying, odourless rust-prevention oil.

    This is also an important distinction: Hamono Tsubaki is not simply a bottle of 100% pure camellia seed oil. It is a formulated blade-care product containing mineral oil, camellia seed oil and other ingredients.

    That difference is one reason I am interested in trying it properly myself.

    👉 INTERNAL LINK: Is an Expensive Japanese Knife Really Worth It?

    A good Japanese knife can last for many years, but price alone does not protect it. How the knife is used, sharpened, cleaned and stored matters just as much.

    Good Knife Care Is About Understanding Your Knife


    180mm Santoku Aogami #2 Green Micarta Handle with Turquoise Spacer

    After more than 25 years in kitchens, I still do not believe there is one maintenance routine that suits every Japanese knife or every cook.

    A stainless VG10 knife used every day has very different maintenance needs from an Aogami carbon steel knife that might remain in storage for several months.

    👉 INTERNAL LINK: 一目惚れ Hitomebore | 7 Powerful Reasons to Fall in Love With a Japanese Knife

    Understanding the steel, how frequently you use the knife and how you store it is more useful than blindly following a traditional routine.

    That is also why my old sticky-oil experience does not make me dismiss camellia oil. Instead, it makes me want to understand and use the right product correctly.

    A New Knife-Care Product Coming to Asaoya Yaichi

    Asaoya Yaichi

    Kurobara Hamono Tsubaki will soon be available from Asaoya Yaichi in Australia.

    Once it arrives, I will use it myself and see how it performs with the carbon steel knives I actually work with. Rather than recommending something simply because it is traditional, I prefer to understand how it works in real use.

    Japanese knives are tools designed to be used, but looking after them properly is part of keeping them working for years. Sometimes that means sharpening. Sometimes it means removing rust. And sometimes, especially before longer storage, it may be as simple as applying the right protective oil — and remembering that a little can go a long way.

  • Tosa Knives and Kurouchi — Why the Black Finish Became So Common

    Tosa Knives and Kurouchi — Why the Black Finish Became So Common

    Ishizuchi Kanamono Manufactory

    Tosa Knives are often easy to recognise. Among polished Japanese knives, Damascus patterns and mirror finishes, many traditional Tosa knives have a much rougher appearance: a dark, almost black surface left above the cutting edge.

    This finish is called Kurouchi (黒打ち).

    Today, Kurouchi has become something many people associate with traditional Japanese knives. But while researching the history of Tosa Knives, I became curious about a more specific question: why does Kurouchi seem to fit Tosa knives so naturally?

    The answer is not as simple as I first expected.

    Tosa Knives Began as Tools for Working People


    From Agricultural Tools to Kitchen Knives

    To understand Kurouchi, we first need to understand where Tosa Knives came from.

    Kochi Prefecture has one of Japan’s strongest historical connections with forestry. Surrounded by mountains and forests, the region developed a long tradition of producing tools for agriculture and forestry.

    Tosa blacksmiths were not historically making only kitchen knives. They produced sickles, hatchets, saws and many other cutting tools required by farmers and forestry workers.

    According to Kochi City, records from the Chosokabe land survey of 1590 indicate that there were 399 blacksmiths in the region. Demand for agricultural and forestry blades later increased during the Edo period as these industries developed.

    These were working tools.

    They needed to cut well, survive hard use and remain practical.

    👉 INTERNAL LINK: Link here to “The History of Tosa Knives”

    That practical background is important when looking at the appearance of traditional Tosa blades.

    Tosa Knives and the Tradition of Free Forging

    One of the defining characteristics of Tosa cutlery is a technique known as Jiyu Tanzo (自由鍛造), or free forging.

    Rather than simply cutting a standard shape from sheet steel, Tosa blacksmiths traditionally forged blades according to their intended purpose. Different regions, working conditions and users could require different dimensions and shapes.

    Kochi Prefecture still describes this free-forging tradition as one of the defining characteristics of Tosa cutlery.

    In other words, the blade begins with its purpose.

    Its shape follows what the user needs.

    That philosophy helps explain why the sometimes rugged appearance of traditional Tosa Knives does not feel out of place. These blades developed from a culture where function mattered enormously.

    👉 INTERNAL LINK: Link here to “What Makes Tosa Knives Different from Other Japanese Knives”

    What Is Kurouchi on Tosa Knives?


    165mm Kiritsuke Thick Deba Aogami #2 Kurouchi Walnut Octagonal Handle

    Kurouchi literally refers to the dark finish left on part of a forged blade.

    During forging and heat treatment, a dark oxide scale forms on the steel. Instead of polishing the entire surface until it becomes bright and uniform, part of that dark surface is left visible while the cutting area is ground and sharpened.

    The result is the familiar contrast between the dark upper blade and the exposed steel closer to the edge.

    It looks rustic because, in a sense, it is.

    Kurouchi is not Damascus decoration painted onto a blade. The dark appearance comes from the blade-making process itself.

    👉 INTERNAL LINK: Link here to “Kurouchi Japanese Knives — What I Learned After Removing It”

    Why Did Kurouchi Become So Common on Tosa Knives?

    This is where I think we need to be careful.

    I could not find a reliable historical source that simply states: “Kurouchi became common in Tosa because of this one reason.”

    So I do not want to invent a history just because it makes a good story.

    What we can establish is that Tosa cutlery developed strongly alongside agriculture and forestry, that practical working blades were extremely important to the region, and that free forging became a defining part of its manufacturing culture.

    From that background, leaving part of the forged surface unpolished makes practical sense. It avoids the need to polish every part of a working blade purely for appearance while retaining the unmistakable character of forging.

    That does not prove that Kurouchi originated in Tosa.

    It almost certainly should not be described that way.

    But it does help explain why Kurouchi and Tosa Knives feel so naturally connected.

    👉 INTERNAL LINK: Link here to “Handmade Japanese Knives — Why No Two Are Exactly the Same”

    From Practical Finish to Japanese Character


    240mm Thick Deba Aogami #2 Kurouchi Walnut Handle

    Something interesting happened to me today here in Australia.

    I visited a café to show the owner some of our knives. When he saw one of the Kurouchi knives, he told me:

    “I want to have this kind of Japanese-looking knife.”

    That comment stayed with me.

    A finish that historically makes perfect sense on a practical forged tool now communicates something completely different on the other side of the world.

    It communicates Japan.

    The uneven black surface, the visible contrast with the sharpened steel and the slightly rugged appearance tell a story before anyone even uses the knife.

    For me, that is part of what makes Tosa Knives fascinating.

    Tosa Knives: Kurouchi Feels at Home in Tosa


    180mm Kiritsuke Aogami #2 Kurouchi Walnut Octagonal Handle

    I cannot say that Kurouchi was invented in Tosa, nor can I point to a single historical event that explains exactly why it became so strongly associated with Tosa blades.

    But perhaps that is not the most important point.

    Tosa cutlery grew from forests, farms, blacksmiths and people who needed reliable tools. Its tradition of free forging placed purpose before perfect uniformity.

    Kurouchi fits that philosophy remarkably well.

    What was once simply a practical way to finish a forged blade has also become part of the visual character that people around the world now recognise as distinctly Japanese.

    And today, standing in a café in Australia and hearing someone say, “This is the kind of Japanese knife I want,” I was reminded that the old character of Tosa still has the power to speak for itself.

  • Aogami and Shirogami | 7 Fascinating Things I Learned About Blue and White Paper Steel

    Aogami and Shirogami | 7 Fascinating Things I Learned About Blue and White Paper Steel


    Kiritsuke Aogami #2 Kurouchi Walnut Octagonal Handle

    Aogami and Shirogami are two traditional Japanese carbon steels that I only started learning about after entering the Japanese knife business.

    I have worked as a professional chef for more than 25 years, but I have a confession to make.

    Until I started selling Japanese knives, I didn’t even know what Aogami and Shirogami were.

    To be honest, I didn’t know there were so many different types of stainless steel either. VG10, Ginsan, SG2… I had used knives for years without paying much attention to what the steel was actually called.

    And even now, I’m still learning what makes each steel different.

    As a chef, I had always judged a knife in a much simpler way. Does it cut well? How does it feel in my hand? How does it feel on the whetstone? And does it work well for the job I need it to do?

    Then, after starting my knife business, I kept seeing the words Aogami and Shirogami.

    Blue Paper Steel. White Paper Steel.

    And one day I thought:

    Why blue? Why white?

    I honestly had no idea.

    So I decided to look it up.

    1. Why Are Aogami and Shirogami Called Blue and White Paper Steel?

    Ishizuchi Kanamono Manufactory

    The answer was much simpler than I expected.

    The steel itself is not blue or white.

    The names Aogami and Shirogami come from the coloured paper traditionally used to distinguish different grades of Yasugi Specialty Steel.

    “Ao” means blue in Japanese, while “Shiro” means white.

    That is why Aogami became known as Blue Paper Steel and Shirogami as White Paper Steel.

    After more than 25 years of using knives, I had never once wondered about this.

    Sometimes the simplest questions are the ones we forget to ask.

    2. So, What Exactly Is Shirogami?

    Once I understood the name, the next question was obvious.

    What is actually different about the steel?

    Shirogami is a high-purity carbon steel with tightly controlled impurities. Its relatively simple composition allows it to take a very fine edge, and it has a strong reputation for responding beautifully to whetstones.

    Of course, it is still carbon steel.

    That means moisture, acidic foods and poor maintenance can cause discolouration and eventually rust.

    It can also develop a natural patina through normal use.

    👉 INTERNAL LINK: Read more about Japanese knife patina:
    https://blog.asaoyayaichi.com.au/japanese-knife-patina/

    For someone used to stainless steel, this extra maintenance may seem inconvenient. For others, it is simply part of the character of a traditional carbon-steel knife.

    3. How Is Aogami Different from Shirogami?

    This is where things started getting more interesting for me.

    Aogami contains alloying elements such as chromium and tungsten in addition to carbon. These additions help increase wear resistance and edge retention.

    In simple terms, Aogami is designed to maintain its cutting edge well.

    The trade-off is that greater wear resistance can also mean more effort when sharpening compared with a simpler carbon steel such as Shirogami.

    Before starting a knife business, I never thought about knives in terms of chromium, tungsten or carbon percentages.

    I simply knew whether I liked using a knife or not.

    Learning about the steel has given me another way to understand some of those differences.

    4. Aogami #1, #2 and Aogami Super

    Then I discovered that Aogami itself was not just one steel.

    There is Aogami #1, Aogami #2 and Aogami Super.

    Very simply, the different grades have different carbon and alloy compositions. Aogami #1 has more carbon than #2, while Aogami Super uses additional alloying elements and is known for high hardness and excellent edge retention when properly heat treated.

    At first, it is tempting to think that a higher specification must automatically mean a better knife.

    But the more I learn about Japanese knives, the less I think that way.

    The steel is only one part of the story.

    Heat treatment, blade geometry, grinding, sharpening and the skill of the maker can all affect how the finished knife performs.

    👉 INTERNAL LINK: Read more about Japanese knife hardness and HRC:
    https://blog.asaoyayaichi.com.au/japanese-knife-hardness-hrc/

    5. Shirogami Also Has Different Grades

    Then, of course, I learned that Shirogami also comes in different grades.

    Shirogami #1, #2 and #3 have different carbon contents, with #1 containing more carbon than #2 and #3 containing less.

    Again, I don’t think this means we can simply rank them from “best” to “worst.”

    This is something I have come to understand since entering the knife business.

    Two handmade Japanese knives using the same steel can still feel very different.

    The maker, heat treatment, thickness, blade geometry, sharpening and even the intended purpose of the knife all matter.

    👉 INTERNAL LINK: Why no two handmade Japanese knives are exactly the same:
    https://blog.asaoyayaichi.com.au/handmade-japanese-knives/

    6. Is Aogami Better Than Shirogami?


    180mm Santoku Aogami #2 Green Micarta Handle with Turquoise Spacer

    This was probably my biggest question when I first started learning about Aogami and Shirogami.

    Which one is better?

    After looking into it, I think that may be the wrong question.

    Aogami is well known for edge retention and wear resistance. Shirogami is famous for its sharpening response and ability to take a very refined edge.

    But a knife is something we actually use.

    How often do you sharpen? What ingredients do you cut? How do you use your knife? Do you enjoy sharpening? How much maintenance are you comfortable with?

    And most importantly, how does the knife actually feel when you use it?

    👉 INTERNAL LINK: Read more about Kireaji — the feeling of sharpness:
    https://blog.asaoyayaichi.com.au/japanese-knife-sharpness/

    Specifications can explain part of a knife, but they cannot completely describe the experience of using one.

    7. What I Learned About Aogami and Shirogami

    The biggest thing I learned while researching Aogami and Shirogami was not actually about carbon percentages or alloying elements.

    It was how much I still have to learn.

    I have spent more than 25 years using knives professionally, but that does not mean I spent 25 years studying knife steel.

    I was a chef.

    I picked up a knife, used it, sharpened it, washed it, dried it and went back to work.

    Only after starting my knife business did I begin paying much more attention to the steels behind the knives.

    👉 INTERNAL LINK: Read more about Japanese knife balance:
    https://blog.asaoyayaichi.com.au/japanese-knife-balance/

    And I actually enjoy discovering these things now.

    Aogami. Shirogami. VG10. Ginsan. SG2.

    Names that once meant very little to me are gradually starting to make more sense.

    This time, it started with an extremely simple question.

    Why blue? Why white?

    Now I know.

    But learning about Aogami and Shirogami also reminded me that steel specifications are only part of what makes a Japanese knife interesting.

    The maker matters. Heat treatment matters. Geometry matters. Sharpening matters.

    And finally, the person holding the knife matters.

    So I don’t think we need to decide that Aogami is simply better than Shirogami, or vice versa.

    They are different steels with different characteristics.

    And I’m still learning about both.

    Maybe that is part of the fun.

    一目惚れ Hitomebore | 7 Powerful Reasons to Fall in Love With a Japanese Knife


    Kiritsuke Aogami #2 Kurouchi Walnut Octagonal Handle

    I sell Japanese knives for a living. The problem is, sometimes I don’t want to sell them.

    Right now, there is one Japanese knife in the Asaoya Yaichi collection that I keep looking at and thinking, “Maybe I should keep this one for myself.”

    It is an Aogami #2 knife with a polished blade, a green Micarta handle and a beautiful turquoise accent.

    I originally selected it to sell.

    That was the plan, anyway.

    A Japanese Knife Is More Than Its Specifications


    180mm Santoku SG2 Rosewood Octagonal Handle

    After more than 25 years working as a professional chef in Japan and Australia, I have used many Japanese knives. But honestly, I have never chosen a knife by specifications alone.

    Of course, steel matters. Hardness matters. Blade shape, handle, balance and craftsmanship matter too.

    Over the years, I have developed my own preferences. I personally like Aogami steels, for example. From my experience, I find them relatively easy to sharpen and enjoyable to use.

    But there is another side to choosing a Japanese knife that is much harder to put into numbers.

    Sometimes, you simply see a knife and think:

    “That’s the one.”

    That is exactly what happened with this Aogami #2 knife.

    I like the polished blade because it does not immediately have the rustic appearance many people associate with carbon steel. Underneath that clean finish, however, is Aogami #2 — a steel I already know and like.

    Then there is the handle.

    Samurai Century

    The green Micarta gives it a modern appearance, while the turquoise band adds something completely different.

    To my eyes, there is even a little Wabi-Sabi in that turquoise detail. It is unusual without being too flashy, and it gives the knife its own character.

    I have plenty of knives around me.

    But I keep looking at this one.

    That probably says something.

    Choosing Japanese Knives for Asaoya Yaichi

    There is also a reason this story matters to me as the person behind Asaoya Yaichi.

    When you buy a Japanese knife online, you cannot physically pick up every knife before making your decision.

    I understand that.

    That is why I believe the selection before a knife appears in the store is important.

    I have spent more than 25 years using knives in professional kitchens. When selecting knives for Asaoya Yaichi, I want to actually see them, hold them and look closely at their quality, construction and overall feel.

    I do not choose knives simply because a specification sheet looks impressive.

    I want to offer knives that I would be happy to own myself.

    Quality Still Matters

    Love at first sight is not enough by itself.

    A Japanese knife is still a working tool.

    I do not believe an expensive knife is automatically perfect for everyone, but I do believe good materials, skilled craftsmanship and careful finishing have real value.

    Very cheap knives can do a job, but there are usually compromises somewhere.

    A quality knife can also change the way you treat it. When you own something you genuinely value, you tend to clean it carefully, sharpen it properly and want to keep it for many years.

    But I also think it is perfectly fine to choose a knife because something about it simply catches your eye.

    For me, it is this one.

    I like the Aogami #2 steel.

    I like the polished blade.

    And I love that turquoise detail.

    I selected this knife for Asaoya Yaichi because I thought it was something worth offering to our customers.

    The only problem is that I may have selected it a little too well.

  • 愛着 Aichaku | 7 Powerful Ways a Japanese Knife Becomes Truly Yours

    愛着 Aichaku | 7 Powerful Ways a Japanese Knife Becomes Truly Yours

    Ishizuchi Kanamono Manufactory

    A Japanese knife can become much more than just a tool.

    After more than 25 years working as a professional chef in Japan and Australia, I have used many knives. Some have been sharpened countless times. Some have developed scratches, sharpening marks, patina, and other signs of daily work.

    Over time, those imperfections can become part of what makes a knife feel personal.

    But recently, a chef I work with reminded me that there is another way to love a knife.

    He had bought a new knife and was genuinely disappointed when he noticed a small scratch on the blade. The scratch had absolutely no effect on its performance, but that wasn’t the point.

    He wanted to keep his knife beautiful.

    It made me think that perhaps there are two very different ways to develop Japanese Knife Attachment.

    One is to let a knife change through years of use.

    The other is to protect its beauty for as long as possible.

    And I think both are completely valid.

    1. Japanese Knife Attachment Can Grow Through Use

    For many professional chefs, a knife becomes personal simply by using it.

    You sharpen it. You learn its balance. You understand how much pressure it needs and how the blade reacts to different ingredients.

    Eventually, you pick it up without even thinking.

    Small scratches appear. The polish changes. Carbon steel may develop a patina. The handle slowly begins to show signs of years of work.

    For some knives, I actually enjoy watching this happen.

    Those marks aren’t necessarily damage. They can be evidence that the knife has spent years doing exactly what it was made to do.

    A working knife doesn’t always need to look new.

    👉 INTERNAL LINK: Ancient Patina 古色 | 7 Powerful Truths About Japanese Knife Patina That Even Surprised Me

    Sometimes it looks better because it doesn’t.

    2. A Small Scratch Can Mean Something Completely Different

    His Knive

    The chef I mentioned earlier showed me the opposite perspective.

    His knife still performed exactly the same after the scratch appeared, but emotionally, something had changed.

    He had bought something he considered beautiful, and he wanted to preserve that beauty.

    I understand that.

    Japanese knives aren’t only cutting tools. They can represent craftsmanship, tradition, design, and personal taste.

    A polished blade, unusual handle, Damascus pattern, kurouchi finish, or beautiful forging can be the reason someone falls in love with a particular knife.

    Telling that person, “It’s just a tool,” misses the point.

    There are knives we want to use hard.

    And there are knives we want to protect.

    3. Patina and Scratches Aren’t the Only Way to Build Character

    Patina and Scratches

    There is a romantic idea that a Japanese knife should become scratched, sharpened, and covered with the signs of years of use.

    I like that kind of knife.

    But it doesn’t mean every knife needs to age that way.

    A carbon steel knife that develops a beautiful patina can be wonderful. A knife that remains incredibly clean and polished after years of careful ownership can also be beautiful.

    Both require attention.

    One owner may enjoy watching the steel slowly change.

    Another may carefully polish and maintain the blade to prevent unnecessary scratches.

    The results may look completely different, but both owners are building a relationship with their knives.

    That, to me, is part of Japanese Knife Attachment.

    4. Your Hand Learns the Knife Too

    Appearance is only one part of the relationship.

    After using the same knife repeatedly, you begin to understand things that specifications alone can’t explain.

    You know how the handle sits in your hand. You understand its balance point. You know how the blade moves through fish, meat, and vegetables.

    👉 INTERNAL LINK: Japanese Knife Handles | 7 Powerful Reasons the Right Handle Matters

    You may also notice that two knives that appear similar on paper can feel completely different when cutting.

    Steel, hardness, geometry, sharpening, weight, and balance all contribute to that feeling, but the person holding the knife matters too.

    👉 INTERNAL LINK: 切味 Kireaji | 7 Surprising Truths About What Makes a Japanese Knife Feel Sharp

    Eventually, your hand learns the knife almost as much as you learn how to use it.

    That familiarity takes time.

    5. Sharpening Slowly Makes the Knife Your Own

    Sharpening is another important part of this process.

    Every time you sharpen a knife, you make a tiny change to the blade.

    After years of sharpening, a professional chef’s knife may look very different from the same model when it was new.

    Personally, I like that with my working knives.

    The blade carries the history of cooking, sharpening, maintenance, mistakes, corrections, and experience.

    Keeping your sharpening stones flat is also part of maintaining that relationship with your knife.

    A well-used knife develops a history.

    And that history belongs to the person who used it.

    6. Some Knives Are Tools — Others Are Showpieces

    This distinction has become more interesting to me recently.

    There are knives I want to use without worrying too much about cosmetic changes.

    They are working knives.

    Their purpose is performance. If normal use creates scratches, sharpening marks, or patina, I can accept that.

    But there are other knives that make you stop and look at them.

    Beautiful polishing. An unusual handle. Damascus patterns. Traditional finishes. Exceptional craftsmanship.

    Those knives can create a completely different feeling.

    A handmade Japanese knife can also become more personal because no two handcrafted knives are ever perfectly identical.

    Perhaps that is why some knives eventually become difficult to replace, even when newer or more expensive knives are available.

    7. My Next Japanese Knife May Be an Experiment


    Knife Collection

    If I buy another knife specifically as a showpiece, I want to try something I haven’t really done before.

    I want to see how carefully I can preserve it.

    Not by putting it in a box and never using it.

    I still want to use it.

    But I would pay much more attention to how I clean it, dry it, sharpen it, store it, and protect the blade from unnecessary scratches.

    Instead of allowing time to naturally transform the knife, I would see how much of its original beauty I could preserve.

    In a way, that would still be “raising” the knife.

    Just differently.

    Maybe after five or ten years, it would tell a completely different story from the working knives I have used throughout my career.

    I think both stories would be worth telling.

    There Is No Single Right Way to Love a Japanese Knife

    Two people can own similar Japanese knives and develop completely different relationships with them.

    One may proudly accept the scratches, sharpening marks, patina, and years of professional use.

    Another may carefully protect the polish and feel disappointed by even the smallest scratch.

    Neither is wrong.

    A Japanese knife doesn’t become personal simply because it gets old.

    It becomes personal because of the time, care, work, and attention you give it.

    For some people, beauty comes from allowing a knife to change.

    For others, beauty comes from trying to preserve it.

    Maybe Aichaku — 愛着 is found somewhere between the two.

    And perhaps the most special Japanese knife isn’t always the newest or most expensive one.

    It’s the one you wouldn’t want to replace.

  • Ancient Patina 古色 | 7 Powerful Truths About Japanese Knife Patina That Even Surprised Me

    Ancient Patina 古色 | 7 Powerful Truths About Japanese Knife Patina That Even Surprised Me

    Ishizuchi Kanamono Manufactory

    If you own or are thinking about buying a carbon steel Japanese knife, you’ve probably heard the term Japanese Knife Patina. Until I started selling handcrafted Japanese knives, I honestly thought any discoloration on a blade was something to avoid.

    What surprised me was discovering that many knife enthusiasts actually appreciate a beautiful patina. For some, it’s not damage at all—it’s a sign that the knife is being used, cared for, and developing its own unique character.

    In this article, I’ll explain what Japanese Knife Patina really is, how it differs from rust, and why so many experienced knife users see it as something worth embracing.

    What Is Japanese Knife Patina?

    Patina

    Japanese Knife Patina is a natural oxide layer that develops on carbon steel after repeated use. It often appears in shades of blue, grey, purple, or dark charcoal depending on the foods you cut and how you care for the knife.

    Unlike red rust, patina is generally stable and can even help slow further oxidation.

    Many professional chefs never try to remove it. Instead, they simply keep the blade clean and dry after use.

    ➡ Read more: Beginner’s Guide to Japanese Kitchen Knives

    Why Japanese Knife Patina Is Different From Rust

    One of the biggest misconceptions is that every color change means corrosion.

    Here’s the difference:

    Japanese Knife Patina

    • Blue, grey, or dark tones
    • Forms naturally during normal use
    • Can act as a protective oxide layer
    • Often appreciated by carbon steel knife users

    Rust

    • Red or orange color
    • Caused by moisture left on the blade
    • Can damage the steel if ignored
    • Should be removed as soon as possible

    Understanding this difference helps you enjoy your knife with more confidence instead of worrying every time the blade changes color.

    ➡ Read more: Why Do Japanese Knives Rust So Easily?

    Why Some Knife Enthusiasts Love Japanese Knife Patina

    This was the part that surprised me the most.

    For years I simply used carbon steel knives because they performed exceptionally well. I never thought much about the color changing over time.

    After starting Asaoya Yaichi, I learned that many collectors and professional chefs actually enjoy watching their Japanese Knife Patina develop.

    To them, every knife tells a story.

    The blade reflects years of cooking, countless ingredients, and the owner’s personal journey.

    No two patinas are exactly alike, making every knife even more unique.

    Does Everyone Want a Patina?

    Mirror Polished

    Not at all.

    Some people love the bright mirror finish of a freshly polished knife.

    Others prefer the rich character that develops through daily use.

    Neither preference is right or wrong.

    It’s simply a matter of taste.

    A mirror-polished knife highlights craftsmanship, while a beautiful Japanese Knife Patina reflects years of real-world experience.

    ➡➡ Professional Choice | Why I Still Use Carbon Steel for Sashimi After 25 Years

    How to Care for Japanese Knife Patina

    If you own a carbon steel knife, proper maintenance is still essential.

    Keep the blade clean

    Wash the knife by hand after use using mild detergent.

    Dry immediately

    Never leave water on carbon steel.

    Store properly

    Keep the knife in a dry location with good airflow.

    Don’t panic over color changes

    Blue or grey tones are often completely normal.

    The goal isn’t to prevent every change.

    The goal is to prevent red rust.

    My Honest Discovery About Japanese Knife Patina

    I spent more than 25 years working as a professional chef.

    Yet one thing I didn’t truly appreciate until I started selling handcrafted Japanese knives was how differently people view Japanese Knife Patina.

    I always focused on performance.

    Many enthusiasts also appreciate the story the blade tells.

    That changed the way I look at carbon steel knives.

    A handcrafted Japanese knife isn’t just a cutting tool.

    It’s something that evolves with its owner over time.

    Perhaps that’s one of the reasons handmade Japanese knives continue to fascinate so many people around the world.

    Whether you prefer a mirror finish or a naturally developed Japanese Knife Patina, both represent different ways of appreciating handcrafted Japanese knives.

    The other celebrates experience.

    Whichever you prefer, the most important thing is to enjoy using your knife and taking proper care of it.

  • Hardness 硬度 | 7 Powerful Truths About Japanese Knife HRC That Surprised Even a Chef

    Hardness 硬度 | 7 Powerful Truths About Japanese Knife HRC That Surprised Even a Chef

    Ishizuchi Kanamono Manufactory

    For more than 25 years, I have worked as a professional chef using Japanese knives almost every day. Surprisingly, although I often saw numbers like HRC 60, HRC 61, or HRC 63, I never truly understood what they meant. I simply assumed that a higher number meant a better knife.

    As I began selling handcrafted Japanese knives through Asaoya Yaichi, customers started asking about Japanese knife hardness more often. Rather than pretending I knew every technical detail, I decided to research it properly.

    What I discovered changed the way I think about knives. More importantly, I realised that my experiences in professional kitchens over the last 25 years matched what the science says about knife hardness.

    If you’ve ever wondered what HRC really means, whether a harder knife is always better, or how hardness affects sharpening, this guide is for you.

    ➡ Internal Link: Beginner’s Guide to Japanese Kitchen Knives

    What Is Japanese Knife Hardness?


    240mm Thick Deba Aogami #2 Kurouchi Walnut Handle

    Japanese knife hardness is usually measured using the Rockwell Hardness C Scale (HRC). This test measures how resistant the steel is to indentation using a diamond-tipped tester.

    The higher the HRC number, the harder the steel.

    However, this does not automatically mean the knife is better.

    Hardness is only one characteristic of a knife. Heat treatment, steel quality, blade geometry, sharpening, and craftsmanship all play equally important roles.

    A knife with perfect balance will usually outperform a knife that simply has the highest hardness rating.

    ➡ Internal Link: Carbon Steel vs Stainless Steel | Which Should You Choose?

    Why Japanese Knife Hardness Matters


    165mm Usuba A8 Hammered Damascus Black & Red Octagonal Handle

    Japanese knife hardness affects several important characteristics.

    Better Edge Retention

    Harder steel usually keeps its edge much longer.

    That means you can prepare many more ingredients before the knife begins to lose its sharpness.

    This is one reason many Japanese knives are loved by professional chefs.

    More Difficult Sharpening

    The same hardness that keeps the edge sharp also makes the knife more difficult to sharpen.

    Removing steel takes longer, especially if the blade has become quite dull.

    Greater Risk of Chipping

    Very hard steel is less flexible.

    If used incorrectly on bones, frozen food, or by twisting the blade sideways, small chips can occur.

    That doesn’t mean the knife is weak—it simply means it should be used correctly.

    Japanese Knife Hardness in Real Kitchen Experience


    210mm Sujihiki Aogami #2 Kurouchi Magnolia Handle

    This was probably the biggest surprise for me.

    I realised that although I didn’t know the HRC numbers, I had already experienced the difference between softer and harder steels throughout my career.

    Years ago, I used a sujihiki made from relatively soft steel.

    It was so flexible that if I applied too much pressure while sharpening, I could actually feel the blade flex slightly on the whetstone.

    The edge didn’t last particularly long.

    However, when it became dull, I could restore an excellent edge very quickly.

    It sharpened easily and always performed well enough for daily professional work.


    240mm Sujihiki VG10 Hammered 17 Layer Damascus Mahogany

    Later, I switched to harder stainless steel knives.

    The difference was immediately obvious.

    When freshly sharpened, the cutting performance was incredible.

    The edge stayed sharp much longer than my previous knife.

    But there was another side to the story.

    Once the knife finally became dull, it was much harder to bring back.

    It took considerably longer to raise a burr, and if I accidentally changed the sharpening angle, correcting the edge required much more patience.

    After researching Japanese knife hardness, I finally understood why.

    Harder steel offers outstanding edge retention, but it also demands greater sharpening skill.

    Softer steel loses its edge sooner, yet it rewards the user by being forgiving and much easier to sharpen.

    Neither is objectively better.

    They simply suit different users and different situations.

    Common HRC Ranges for Japanese Knives


    180mm Santoku Aogami #2 Green Micarta Handle with Turquoise Spacer

    Although every manufacturer uses different heat treatments, these are general guidelines.

    HRC 55–58

    • Tough and flexible
    • Easy to sharpen
    • Loses its edge relatively quickly

    HRC 59–61

    • Excellent balance
    • Suitable for many home cooks
    • Common among quality Japanese knives

    HRC 61–64

    • Outstanding edge retention
    • Very sharp cutting performance
    • Requires proper technique and sharpening skills

    Above HRC 64

    • Extremely hard
    • Exceptional edge retention
    • Less forgiving and often intended for experienced users

    Remember, these are only general ranges.

    Steel composition and heat treatment are often more important than the HRC number alone.

    ➡ Internal Link: Professional Choice | Why I Still Use Carbon Steel for Sashimi After 25 Years

    Should You Buy the Hardest Japanese Knife?


    180mm Santoku SG2 Rosewood Octagonal Handle

    Many people assume that the highest HRC automatically means the best knife.

    After researching this subject, I don’t believe that’s true.

    A knife should match the way you cook.

    If you enjoy sharpening and want maximum edge retention, harder steel can be fantastic.

    If you prefer quick maintenance and easy sharpening, a slightly softer blade may actually make your cooking more enjoyable.

    The best knife isn’t the one with the highest number.

    It’s the one that suits your cooking style.

    Final Thoughts on Japanese Knife Hardness


    Ginsan Nashiji Forged Magnolia Octagonal Handle Buffalo Horn Ferrule series

    Researching Japanese knife hardness taught me something I honestly didn’t know after more than 25 years in professional kitchens.

    I had always judged knives by how they performed.

    Only later did I realise that hardness helps explain why they perform that way.

    Today, I still don’t choose a knife based only on its HRC rating.

    I look at the steel, the heat treatment, the craftsmanship, the intended purpose, and how the knife feels in my hand.

    The HRC number is useful, but it’s only one piece of a much bigger picture.

    If this article helped you understand Japanese knife hardness a little better, I hope it also gives you more confidence when choosing your next knife.

  • Handmade Japanese Knives | 7 Fascinating Reasons No Two Are Ever Exactly the Same

    Handmade Japanese Knives | 7 Fascinating Reasons No Two Are Ever Exactly the Same


    Ishizuchi Kanamono Manufactory 

    When I imported my first batch of handmade Japanese knives, I ordered two or three of the same model. I expected them to look almost identical. After all, they had the same blade length, the same steel, the same handle material, and were made by the same craftsman.

    But when I placed them side by side, I noticed something unexpected.

    No two knives were exactly the same.

    At first, I wondered if something was wrong. Then I realized I wasn’t looking at imperfections—I was looking at the beauty of true craftsmanship. That moment changed the way I saw handmade Japanese knives, and it reminded me why so many people around the world value them so highly.

    Handmade Japanese Knives Reflect the Hands That Made Them

    One of the biggest differences between handmade Japanese knives and factory-produced knives is that every step involves skilled human hands.

    Even when a blacksmith follows the same design repeatedly, every hammer strike is unique. Every blade is shaped, ground, and finished by hand. Small differences naturally appear throughout the process, and those differences become part of each knife’s character.

    Rather than being flaws, they are evidence that a real craftsman created the knife instead of a machine.

    Handmade Japanese Knives Have Unique Kurouchi and Hammered Finishes


    165mm Kiritsuke Aogami #2 Kurouchi Walnut Octagonal Handle

    If you compare two handmade Japanese knives with a Kurouchi or Tsuchime finish, you’ll quickly notice subtle differences.

    The dark Kurouchi surface may have a slightly different texture.

    The hammered pattern may catch the light differently.

    Even the polish near the edge can vary from one knife to another.

    These details cannot be copied perfectly because they are created by hand, making every knife feel genuinely individual.

    ➡ Internal Link: Why I Still Use Carbon Steel for Sashimi After 25 Years

    Every Wooden Handle Is Naturally Different

    The blade isn’t the only part that tells a story.

    Natural wood has its own grain, color, and texture. Even if two handles are made from the same species of wood, they will never look completely identical.

    Some pieces have darker lines.

    Others have lighter tones.

    Some display dramatic grain patterns, while others appear clean and understated.

    These natural variations make every handmade Japanese knife even more personal.

    Small Differences Are Part of Traditional Craftsmanship


    Ginsan Nashiji Forged Magnolia Octagonal Handle Buffalo Horn

    Modern factories aim for perfect consistency.

    Traditional Japanese workshops aim for exceptional quality.

    That difference is important.

    A craftsman focuses on creating the best possible knife rather than producing thousands of completely identical pieces. Slight variations in finish or appearance are simply part of the handmade process that has been passed down through generations.

    This is one reason collectors, chefs, and cooking enthusiasts often appreciate handmade Japanese knives so much.

    Handmade Japanese Knives Tell Their Own Story


    180mm Santoku VG10N 33 Layer Damascus Green Marble Handle Rainbow Spacer

    When I first compared those identical models, I expected to choose the “best” one.

    Instead, I found myself appreciating each knife for different reasons.

    One had a stronger Kurouchi finish.

    Another had a particularly beautiful wood grain.

    A third had a hammered pattern that reflected light in a unique way.

    None of them were better or worse.

    They simply had different personalities.

    That’s something I never expected before starting Asaoya Yaichi.

    ➡ Internal Link: Monozukuri | Where Japanese Craftsmanship Meets Quiet Beauty

    Why Handmade Japanese Knives Feel More Meaningful

    When you own something made by skilled hands, you begin to notice details that machines simply cannot reproduce.

    Every tiny variation reminds you that someone heated the steel, shaped the blade, sharpened the edge, and carefully finished the knife.

    That human touch creates an emotional connection that goes beyond cutting performance.

    Over time, your knife develops its own story alongside yours.

    Whether you’re preparing dinner at home or working in a professional kitchen, it becomes more than just a tool.

    It becomes something you’ll remember every time you pick it up.

    Why These Differences Should Be Appreciated

    My knives

    Many people assume that two knives with the same specifications should look exactly alike.

    That’s true for mass-produced products.

    It isn’t true for handmade Japanese knives.

    The subtle differences in finish, texture, wood grain, and overall appearance aren’t defects—they’re signs that the knife was made through traditional craftsmanship rather than automated production.

    Once I understood that, I stopped searching for perfect uniformity and started appreciating individuality instead.

    That’s one of the reasons handmade Japanese knives continue to impress me every time I open a new shipment.

    If you’ve only ever owned factory-made knives, seeing several handmade Japanese knives side by side can be a surprising experience.

    You may discover that the small differences are exactly what make each knife special.

    Those details represent tradition, craftsmanship, and the human touch that machines simply cannot replicate.

    If you’re looking for a knife with genuine character rather than perfect uniformity, handmade Japanese knives offer something truly unique.

    Professional Choice | Why I Still Use Carbon Steel for Sashimi After 25 Years

    Ishizuchi Kanamono Manufactory

    If you asked me what knife I still reach for after more than 25 years as a professional chef, my answer might surprise you.

    Despite owning and using modern stainless steel knives such as VG10, Ginsan, and SG2, I still find myself reaching for a carbon steel sashimi knife whenever I’m preparing sashimi.

    Does that mean carbon steel is always better?

    Not at all.

    After using both carbon steel and stainless steel knives in busy professional kitchens, I’ve learned that every knife has its place. Choosing the right knife isn’t about following trends—it’s about understanding what works best for the job.

    Why I Still Choose a Carbon Steel Sashimi Knife


    210mm Sujihiki Aogami #2 Kurouchi Magnolia Handle

    When slicing sashimi, I enjoy using my Aogami carbon steel knife.

    The first thing I notice is how effortlessly it moves through the fish. The edge feels incredibly refined, allowing long, smooth slices with very little resistance.

    Some chefs believe carbon steel produces cleaner cuts and may even reduce unwanted fish aroma, particularly when slicing tuna or bonito. Whether that’s caused by the steel itself or simply by its exceptional edge is still open to debate.

    Personally, I don’t choose carbon steel because I believe it performs miracles.

    I choose it because I enjoy the feeling every time I use it.

    ➡ Internal Link: 👉 Beginner’s Guide to Japanese Kitchen Knives

    Stainless Steel Is Better Than Many People Think


    180mm Santoku SG2 Rosewood Octagonal Handl

    Modern stainless steels have improved dramatically.

    A properly sharpened VG10 sujihiki can produce beautiful sashimi with excellent edge retention and outstanding corrosion resistance.

    If my VG10 sujihiki and my carbon steel knife are both sharpened to the same level, I honestly don’t think most customers would notice any difference once the sashimi reaches the plate.

    This is why I always tell people not to become obsessed with steel names.

    The sharpness of the edge is far more important.

    Why I Use Stainless Steel for Onions and Tomatoes

    Kitchen knife

    My knife choice changes completely when preparing vegetables.

    For onions, tomatoes, citrus fruits, and many everyday ingredients, I usually grab my stainless steel gyuto.

    It’s not because carbon steel cannot cut them.

    It’s because stainless steel lets me work without constantly thinking about maintenance.

    Acidic ingredients can react with carbon steel, so I know I’ll need to clean and dry the knife quickly. During a busy shift, stainless steel simply makes life easier.

    Convenience matters in a professional kitchen.

    ➡ Internal Link: 👉 Why Do Japanese Knives Rust So Easily?

    Sharpness Is More Important Than Steel


    240mm Sujihiki VG10 Hammered 17 Layer Damascus Mahogany

    After more than two decades in professional kitchens, I’ve learned one simple truth.

    A perfectly sharpened VG10 knife is far better than a dull carbon steel knife.

    Many people focus entirely on steel—Aogami, Shirogami, VG10, SG2, or Ginsan.

    But steel only gives a knife its potential.

    Sharpening determines how much of that potential you actually experience.

    Learning how to sharpen properly will improve your cooking far more than changing from one steel to another.

    My Advice After 25 Years

    VG10 & Aogami #2

    People often ask me which knife they should buy.

    My answer is always the same.

    If you enjoy traditional Japanese craftsmanship and don’t mind a little extra care, a carbon steel knife is incredibly satisfying to own.

    If you want outstanding performance with less maintenance, high-quality stainless steel is an excellent choice.

    Neither is wrong.

    In my own kitchen, I still use both.

    Carbon steel for sashimi.

    Stainless steel for much of my everyday preparation.

    Not because one is superior, but because each knife suits a different purpose.

    That, in my opinion, is what professional cooking is all about.

    Final Thoughts

    After more than 25 years as a chef, I’ve stopped asking which steel is “better.”

    Instead, I ask which knife is better for today’s job.

    For me, that often means reaching for a carbon steel knife when preparing sashimi and a stainless steel knife for everyday kitchen work.

    If there’s one lesson I’ve learned throughout my career, it’s this:

    The best knife isn’t determined by its steel alone. It’s determined by how well it’s sharpened, maintained, and matched to the task at hand.

    Whether you choose carbon steel or stainless steel, investing in a quality Japanese knife and learning how to care for it will reward you for years to come.

    The True Value of Japanese Knives | 7 Reasons They Are Worth the Investment

    Why are Japanese knives so expensive?


    Ginsan Nashiji Forged Magnolia Octagonal Handle Buffalo Horn Ferrule

    .

    Why are Japanese knives so expensive?
    It is one of the first questions many people ask when they begin looking for a high-quality Japanese kitchen knife. The answer is not simply branding or appearance. The price often reflects the quality of the steel, the skill of the craftsman, the time required to make the knife, and the performance it can provide over many years.

    Some Japanese kitchen knives can be purchased for a relatively affordable price, while others may cost several hundred dollars or even more. Custom-made knives created by highly skilled craftsmen can reach prices that surprise people who are used to buying mass-produced kitchen knives.

    However, the price of a Japanese knife is not simply based on appearance, branding, or popularity.

    In many cases, the price reflects the quality of the steel, the skill of the craftsman, the time required to make the knife, and the performance it can provide over many years.

    That does not mean everyone needs an expensive knife.

    The real question is not whether a Japanese knife is expensive. The real question is whether the knife offers enough value for the person using it.

    Why Are Japanese Knives So Expensive?

    Ishizuchi Kanamono Manufactory

    Japanese knives are often made very differently from standard factory-produced kitchen knives.

    Many ordinary knives are manufactured in large factories using automated machinery. This allows thousands of similar knives to be produced quickly and sold at a lower price.

    Handcrafted Japanese knives are commonly made in smaller workshops, sometimes by individual blacksmiths, sharpeners, handle makers, and finishers.

    Each stage requires experience, time, and attention.

    The price is therefore not only for the physical knife. It also reflects generations of accumulated knowledge and craftsmanship.

    1. Japanese Knives Use High-Quality Steel

    Asaoya Yaichi

    One major reason Japanese knives are expensive is the quality of the steel.

    Japanese knife makers use steels such as Aogami, Shirogami, Ginsan, VG10, and SG2. Each steel has different characteristics, including sharpness, edge retention, ease of sharpening, corrosion resistance, and toughness.

    Premium steel is more expensive to purchase and can also be more difficult to work with.

    The steel must be heated, forged, shaped, hardened, tempered, ground, and sharpened correctly. A small mistake during heat treatment can reduce the performance of the finished blade.

    A well-made knife is therefore not only about using good steel. It is about understanding how to bring out the best qualities of that steel.

    ➡️ Read more: Carbon Steel vs Stainless Steel – Which Japanese Knife Is Right for You?

    2. Skilled Craftsmen Make Many Japanese Knives by Hand

    A handmade Japanese knife requires a level of skill that usually takes many years to develop.

    Forging a blade, controlling its thickness, creating the correct profile, and producing a fine cutting edge cannot be mastered quickly.

    Even two knives made from the same steel can perform differently depending on the skill of the maker.

    An experienced craftsman understands how the steel responds to heat, pressure, grinding, and sharpening. Much of this knowledge is developed through years of practical experience rather than simply following written instructions.

    When you purchase a handcrafted Japanese knife, part of the price supports the skill and time of the people who made it.

    ➡️Read more: Mass-Produced vs Hand-Forged Japanese Knives – What’s the Difference?

    3. Japanese Knives Are Often Produced in Small Quantities

    Many Japanese knife workshops do not produce huge quantities of knives.

    Some workshops make only a limited number of blades each week or month. Others may produce a particular design only when the right steel, handle material, or craftsman is available.

    Small-batch production makes it difficult to reduce costs in the same way as large-scale factories.

    However, it also allows more attention to be given to each knife.

    Small variations in the finish, hammer marks, blade shape, or handle are often part of the character of a handmade knife rather than signs of poor quality.

    This individuality is one reason many people are attracted to traditional Japanese knives.

    4. Heat Treatment Requires Time and Precision

    Heat treatment is one of the most important stages in knife making.

    The blade must be heated to a carefully controlled temperature and then cooled correctly. It is later tempered to balance hardness with durability.

    If a blade is too soft, it may lose its sharp edge quickly. If it is too hard, it may become more vulnerable to chipping.

    High-performance Japanese knives are often hardened more than typical Western-style kitchen knives. This allows them to take a very fine edge and maintain sharpness for longer.

    Achieving this balance requires experience and precision.

    The customer may not be able to see the quality of the heat treatment, but it has a major effect on how the knife performs.

    5. Sharpening and Finishing Require Considerable Labour

    A Japanese knife may appear simple, but the final stages require a great deal of work.

    The blade must be ground to the correct thickness, the bevels must be shaped, and the cutting edge must be sharpened evenly.

    Some knives also receive additional finishes such as kurouchi, nashiji, tsuchime, Damascus patterns, mirror polishing, or hand engraving.

    The handle must also be fitted correctly.

    Traditional Japanese handles may use magnolia, walnut, rosewood, ebony, buffalo horn, micarta, or other materials. The quality of the handle, spacer, ferrule, and installation can all influence the final cost.

    These details may not change the basic function of the knife, but they can improve comfort, balance, durability, and appearance.

    6. A Good Japanese Knife Can Last for Many Years


    A Kiya Yanagiba Knife Passed Down from My Mother, Over 40 Years Old

    A well-maintained Japanese knife is not a disposable product.

    With proper sharpening, cleaning, drying, and storage, it can be used for many years. Some knives are passed from one generation to the next.

    This changes the way the price should be considered.

    A cheap knife that is replaced repeatedly may eventually cost more than one high-quality knife that is maintained correctly.

    However, long life is not automatic.

    Even an expensive Japanese knife can rust, chip, crack, or become damaged if it is used incorrectly. Carbon steel knives must be kept clean and dry, and thin blades should not be used to cut frozen food, hard bones, or other unsuitable materials.

    The value of a good knife comes from both its construction and the care given by its owner.

    7. Japanese Knives Can Improve the Experience of Cooking

    A high-quality knife does more than cut food.

    It can improve control, precision, efficiency, and enjoyment.

    A sharp knife requires less pressure, which can make delicate cutting easier. It can also help produce cleaner slices of fish, meat, vegetables, herbs, and fruit.

    For professional chefs, these differences can be important because a knife is used for many hours every week.

    For home cooks, the benefit may simply be that food preparation becomes more enjoyable.

    This is difficult to measure with money, but it is one of the main reasons people are willing to invest in quality tools.

    A Chef I Work with Ordered a ¥250,000 Knife

    One of the chefs I work with ordered a custom-made knife when he returned to Japan.

    The knife cost approximately ¥250,000.

    To some people, that may sound far too expensive for a kitchen knife.

    However, for him, the knife was worth the price.

    It was not simply a decorative object or an expensive possession. It was a professional tool that he expected to use regularly. It reflected his preferences, his working style, and the kind of performance he wanted from his equipment.

    He understood what he was buying and believed the knife would provide enough value to justify the cost.

    That does not mean everyone should spend ¥250,000 on a knife.

    Most people do not need to.

    The important lesson is that value is personal.

    One person may be completely satisfied with an affordable stainless steel knife. Another person may prefer to invest in a handmade carbon steel knife. A professional chef may be willing to pay much more for a custom blade that matches a particular cutting style.

    None of these choices is automatically right or wrong.

    Are Expensive Japanese Knives Always Better?


    210mm Sujihiki Aogami #2 Kurouchi Magnolia Handle
    A$270.00

    No.

    A higher price does not always guarantee that a knife is better for every user.

    Some knives are expensive because of rare materials, complex polishing, decorative finishes, limited production, famous makers, or custom specifications.

    These features may be valuable to collectors or experienced chefs, but they may not be necessary for a beginner.

    The best knife depends on what you cook, how often you use it, how comfortable you are with maintenance, and how much you are willing to spend.

    A person who does not want to worry about rust may be happier with Ginsan, VG10, or SG2 stainless steel.

    A person who enjoys sharpening and values traditional character may prefer Aogami or Shirogami carbon steel.

    The most expensive knife is not automatically the best choice.

    How to Decide Whether a Japanese Knife Is Worth the Price

    Before purchasing a Japanese knife, consider how you will use it.

    ➡️ New to Japanese knives? Read our: Beginner’s Guide to Japanese Kitchen Knives

    Think about the type of food you prepare, the knife shape you need, the steel you can maintain, and the size that feels comfortable.

    It is also important to buy from a seller who clearly explains the steel, blade construction, handle, maintenance requirements, and intended use.

    A good knife should suit the user rather than simply impress them.

    At Asaoya Yaichi, the goal is not to convince every customer to purchase the most expensive knife.

    The goal is to help people understand what they are buying and choose a knife that offers genuine value for their needs.

    Final Thoughts: Why Are Japanese Knives So Expensive?

    Japanese knives can be expensive because they combine high-quality steel, skilled craftsmanship, careful heat treatment, detailed sharpening, small-batch production, and traditional knowledge.

    These qualities require time and cannot always be reproduced cheaply.

    However, price alone does not determine value.

    For one person, an affordable knife may be the perfect choice. For another, a handcrafted knife may be worth several hundred dollars. For a professional chef, even a ¥250,000 custom knife may represent a reasonable investment.

    The best knife is not necessarily the most expensive knife.

    It is the knife that suits your work, your cooking, your preferences, and your idea of value.

    A good Japanese knife should not be purchased simply because it is expensive.

    It should be purchased because, for the person using it, it is worth owning.

    壮大 Sōdai | The Knife That Stops People Before They Even Pick It Up


    240mm Thick Deba Aogami #2 Kurouchi Walnut Handle
    A$650.00

    The first time I saw this 240mm Thick Deba Aogami #2, I wasn’t thinking about cutting performance.

    I was thinking about people.

    More specifically, I imagined this knife displayed in one of the restaurants or specialty knife retailers I work with here in Australia.

    I could already picture customers stopping in front of it.

    Looking closer.

    Asking questions.

    After more than 25 years as a chef, I honestly don’t believe everyone needs a knife this large. Throughout my career, I’ve prepared surprisingly large fish using much smaller knives, and that’s still the advice I give today—buy the knife that suits the way you cook.

    So why did I import this 240mm Thick Deba Aogami #2?

    Because every now and then, you come across a knife that deserves attention long before it ever touches a cutting board.

    Why I Chose the 240mm Thick Deba Aogami #2

    Ishizuchi Kanamono Manufactory

    As a chef, I also work closely with restaurants and specialty knife retailers across Australia, supplying carefully selected handcrafted Japanese knives.

    Most knives are chosen because they fit a particular job.

    This one was different.

    The moment I saw it, I thought,

    “If I display this in one of the restaurants or stores I supply, people will stop and look.”

    That first impression mattered.

    Not because it is oversized.

    Not because it is expensive.

    But because it immediately tells a story about traditional Japanese craftsmanship.

    The 240mm Thick Deba Aogami #2 Showcases Authentic Kurouchi Craftsmanship

    Where bold color meets timeless Japanese craftsmanship.

    Of course, appearance alone isn’t enough.

    The blade is forged from Aogami #2 carbon steel, one of Japan’s most respected steels for professional kitchen knives. It offers outstanding sharpness, excellent edge retention, and responds beautifully to sharpening.

    What truly gives this knife its character, however, is the traditional Kurouchi finish.

    Instead of polishing away every mark left by the forging process, the black finish proudly preserves the texture created by fire, hammer, and steel.

    Every mark reminds me that this knife wasn’t mass-produced.

    It was forged by skilled hands.

    Combined with the thick blade and the walnut octagonal handle, the result is a knife with incredible presence while remaining unmistakably traditional.

    Unlike many classic Deba knives, this model features a double bevel edge, making it more approachable for many chefs while maintaining the strength expected from a Thick Deba.

    ➡ Internal Link: Carbon Steel vs Stainless Steel

    Why I Don’t Recommend the 240mm Thick Deba Aogami #2 to Everyone

    This may sound unusual coming from someone who sells Japanese knives.

    But it’s the truth.

    If your goal is simply to process fish efficiently, you probably don’t need a knife this large.

    I’ve spent over two decades in professional kitchens, and I’ve broken down large fish using smaller knives countless times.

    That’s why I always recommend buying the knife that matches your everyday cooking rather than choosing the biggest blade available.

    However, practicality isn’t always the only reason we buy something.

    Sometimes craftsmanship matters.

    Sometimes tradition matters.

    And sometimes you simply admire the work of the blacksmith.

    That’s exactly how I feel about this 240mm Thick Deba Aogami #2.

    ➡ Internal Link: Why Do Japanese Knives Rust So Easily?

    The 240mm Thick Deba Aogami #2 Represents Tosa’s Knife-Making Heritage

    When I hold this knife, I don’t just think about preparing fish.

    I think about generations of craftsmen in Tosa.

    I think about glowing steel, repeated hammer blows, and skills passed down over centuries.

    That heritage is visible in every part of this knife—from the bold Kurouchi finish to the thick spine and beautifully balanced walnut handle.

    It feels less like a tool and more like a piece of functional craftsmanship.

    That’s why I wanted it to become part of the collection I offer to restaurants, retailers, and knife enthusiasts across Australia.

    Asaoya Yaichi

    Would I recommend this knife to every customer?

    Probably not.

    Would I proudly display it in one of the restaurants or specialty knife retailers I work with?

    Absolutely.

    Because I know exactly what happens when someone sees it for the first time.

    They stop.

    They look.

    And they want to hold it.

    That’s exactly why I imported it.

    If you’re looking for authentic handcrafted Japanese knives, whether for your kitchen, your collection, or your restaurant, I’d love to help you discover the right one.

    Kiritsuke Knife | 7 Powerful Reasons to Choose a 180mm Aogami #2 Kurouchi Kiritsuke Knife


    180mm Kiritsuke Aogami #2 Kurouchi Walnut Octagonal Handle
    A$560.00

    If you’re searching for a handcrafted Kiritsuke Knife, few blades capture the spirit of traditional Japanese craftsmanship better than this 165mm Aogami #2 Kurouchi Kiritsuke Knife with a Walnut Octagonal Handle.

    Its deep black Kurouchi finish, handcrafted Aogami #2 steel, and beautifully balanced walnut octagonal handle create far more than an attractive kitchen knife. Together, they produce a tool designed for cooks who appreciate precision, durability, and authentic craftsmanship.

    This knife is also available in 180mm, giving users the option to choose the size that best suits their cooking style.

    For me, after more than 25 years working as a professional chef, this style of Kiritsuke Knife stands out not because it looks impressive, but because it performs exceptionally well every day.

    Why This Kiritsuke Knife Is Different

    The walnut octagonal handle

    Many people first notice the striking Kurouchi finish.

    The deep black surface immediately gives the knife a traditional appearance, but the Kurouchi finish is much more than decoration. It is a natural result of the forging process that Japanese blacksmiths have preserved for generations.

    Because each blade is hand forged, every knife develops its own individual character. No two Kurouchi finishes are exactly alike.

    Combined with handcrafted Aogami #2 steel, this Kiritsuke Knife offers exceptional edge retention, impressive sharpness, and a cutting feel that many professional chefs still prefer over modern alternatives.

    The walnut octagonal handle completes the knife beautifully. It feels warm in the hand, offers excellent control, and remains comfortable even during extended preparation.

    Why I Prefer the Pointed Tip of a Kiritsuke Knife

    Banboo leaf cutting garnish

    One of the biggest advantages of a Kiritsuke Knife is something many people overlook—the pointed tip.

    Some people assume the angled tip exists purely for appearance, but after years of using kiritsuke-style knives professionally, I’ve found the opposite.

    The pointed tip makes detailed work much easier.

    I regularly use it for decorative vegetable carving, trimming delicate ingredients, making decorative cuts in bamboo leaves for plating, opening precise starting cuts, and carefully working around small areas where a rounded blade simply cannot reach as comfortably.

    The additional control may seem like a small difference, but over the course of an entire service, those small advantages become significant.

    Once you become comfortable using a kiritsuke profile, returning to a rounded blade often feels limiting.

    For cooks who value precision, versatility, and control, this is one of the strongest reasons to choose a Kiritsuke Knife.

    Aogami #2 Steel Delivers Outstanding Performance

    Ishizuchi Kanamono Manufactory

    At the heart of this handcrafted Kiritsuke Knife is Aogami #2 steel.

    Among traditional Japanese carbon steels, Aogami #2 has earned an outstanding reputation for combining incredible sharpness with excellent edge retention.

    With proper care, it develops a natural patina that reflects years of use rather than diminishing the knife’s beauty.

    Unlike many stainless steels, Aogami #2 is also highly rewarding to sharpen, allowing experienced users to achieve an exceptionally refined edge.

    For cooks who enjoy maintaining their own knives, this is one of its greatest strengths.

    Choosing Between the 165mm and 180mm Kiritsuke Knife


    165mm Kiritsuke Aogami #2 Kurouchi Walnut Octagonal Handle
    A$520.00

    This model is available in both 165mm and 180mm.

    The 165mm is an excellent all-round size. It feels agile, offers precise control, and is ideal for everyday preparation, vegetables, smaller fish, and general kitchen work.

    The 180mm provides additional blade length, making it more comfortable for larger ingredients and users who simply prefer a longer cutting stroke.

    Neither size is better than the other.

    The right choice depends on your cooking style, workspace, and personal preference.

    Whichever size you select, you’ll enjoy the same handcrafted construction, Aogami #2 steel, Kurouchi finish, and walnut octagonal handle.

    Shikkoku — The Beauty of Deep Black

    Another 漆黒 | Sikkoku

    The Japanese word Shikkoku (漆黒) refers to a rich, profound black.

    It perfectly captures the appearance and character of this handcrafted Kiritsuke Knife.

    Rather than relying on polished surfaces or decorative patterns, the Kurouchi finish celebrates the forging process itself.

    Every hammer strike leaves behind subtle individuality, giving each blade a personality that cannot be mass produced.

    This quiet beauty reflects the philosophy of Japanese craftsmanship, where function and simplicity often create the strongest impression.

    Final Thoughts

    A great Kiritsuke Knife should do more than cut well.

    It should inspire confidence every time you pick it up.

    After more than 25 years working as a chef, I’ve learned that the best knives are the ones you naturally reach for every day.

    This handcrafted 165mm & 180mm Aogami #2 Kurouchi Kiritsuke Knife has exactly that quality.

    Its exceptional steel, practical kiritsuke profile, comfortable walnut octagonal handle, and traditional Kurouchi finish come together to create a knife that is both beautiful and highly functional.

    If you’re looking for an authentic handcrafted Japanese knife that reflects the tradition of Tosa blacksmithing while offering practical performance in everyday cooking, this Kiritsuke Knife is one you’ll appreciate for many years.

    Looking for Your Next Kiritsuke Knife?

    If you’d like to experience the craftsmanship and cutting performance of this handcrafted Aogami #2 Kurouchi Kiritsuke Knife, I invite you to explore the collection at Asaoya Yaichi.

    Every knife is carefully selected from skilled craftsmen in Tosa, Japan, with a focus on traditional craftsmanship, outstanding performance, and long-lasting quality.

    A$480.00

    The 165mm Kiritsuke Thick Deba Aogami #2 Kurouchi Walnut Octagonal Handle belongs firmly in the second category.

    At first glance, its black Kurouchi finish may seem simple compared to polished Damascus blades. But beneath that traditional appearance lies one of the finest examples of Tosa craftsmanship, a style of knife making that has been refined for more than 400 years.

    This isn’t a knife created to follow trends.

    It’s a knife created to continue a legacy.

    What Makes a Tosa Thick Deba Different?

    double-bevel edge

    When many people hear the word Deba, they imagine a heavy, single-bevel knife used only by professional Japanese chefs.

    A Kiritsuke Thick Deba from Tosa is different.

    This knife combines the strength of a traditional thick deba with the practicality of a double-bevel edge, making it far easier for both professional chefs and passionate home cooks to use.

    Whether you’re breaking down a whole fish, trimming large cuts of meat, or tackling tougher ingredients, the extra blade thickness provides confidence and durability that lighter knives simply cannot match.

    For Australian cooks who enjoy preparing salmon, kingfish, tuna, snapper, grouper, or other large reef fish, this style of knife offers versatility that surprises many people.

    Choosing the Right Size


    150mm Kiritsuke Thick Deba Aogami #2 Kurouchi Walnut Octagonal Handle
    A$450.00

    The 165mm Kiritsuke Thick Deba is the size I recommend for most people.

    It offers plenty of power for breaking down larger fish such as salmon and kingfish, while still being comfortable enough for everyday use.

    For those who regularly prepare slightly smaller fish, there’s also a 150mm Kiritsuke Thick Deba Aogami #2 Kurouchi with a Walnut Octagonal Handle available.

    The shorter blade feels a little more agile when working with fish like snapper, grouper, and other medium-sized species where a more compact knife offers greater control.

    To be honest, I don’t think most people need to own both sizes.

    For the vast majority of cooks, the 165mm is the more versatile option.

    The 150mm simply provides another excellent choice if you mainly prepare smaller fish and prefer a slightly more compact knife.

    Forged from Aogami #2 Steel


    Carbon Steel vs Stainless Steel 

    One of the greatest strengths of this knife is its Aogami #2 (Blue Steel #2) core.

    Among Japanese knife enthusiasts, Aogami #2 is respected for offering an outstanding balance of:

    • Exceptional sharpness
    • Excellent edge retention
    • Outstanding toughness
    • Easier sharpening than many modern powder steels

    Unlike stainless steel, Aogami #2 develops character over time.

    As you sharpen it, maintain it, and continue using it, the blade gradually tells the story of its owner.

    That relationship between knife and user is something many handcrafted Japanese knives share—but Tosa blacksmiths have preserved it for generations.

    The Beauty of Kurouchi

    The more I used traditional Tosa knives, the more I realised something.

    Many people first notice the black finish.

    Some even wonder why it isn’t polished.

    The answer lies in tradition.

    The Kurouchi finish is created by leaving part of the protective scale formed during forging on the blade. Rather than polishing everything away, Tosa blacksmiths preserve part of the knife’s history.

    The result is a knife that feels honest.

    Nothing unnecessary.

    Nothing decorative for decoration’s sake.

    Just practical craftsmanship built for daily work.

    Over time, the Kurouchi finish develops its own character, making every knife unique to its owner.

    A Walnut Octagonal Handle Built for Control

    Japanese Knife Handles:
    Why the Handle Matters More Than You Think

    The walnut octagonal handle perfectly complements the blade.

    Walnut provides a warm, natural feel in the hand while remaining durable enough for everyday kitchen use.

    The octagonal shape allows comfortable control from multiple grip positions, whether you’re filleting fish, portioning meat, or performing detailed knife work.

    Combined with the balance of the thick deba blade, the knife feels remarkably secure despite its strength.

    Like the blade itself, the handle isn’t designed to attract attention—it is designed to feel natural after hours of use.

    More Than 400 Years of Tosa Craftsmanship

    Craftsmanship, Passed Down Since the Age of the Chösokabe Clan

    Knife making in Tosa traces its roots back more than four centuries to the era of the Chōsokabe Clan

    Originally producing tools for forestry, farming, and daily life, Tosa’s blacksmiths built a reputation for practical, dependable blades that could withstand demanding work.

    That philosophy remains unchanged today.

    This knife isn’t trying to be flashy.

    It’s trying to perform.

    Every hammer strike, every grind, and every final sharpening reflects a tradition passed down through generations of craftsmen who value function above fashion.

    When you hold this knife, you’re holding far more than steel.

    You’re holding over 400 years of Tosa craftsmanship.

    Why This Knife Represents the Spirit of Tosa

    Wabi-Sabi Vibes

    If someone asked me to choose a single knife that represents traditional Tosa craftsmanship, this would be one of the first I’d recommend.

    Its Kurouchi finish, durable Aogami #2 steel, practical double-bevel design, and handcrafted walnut octagonal handle embody everything I admire about Tosa knives.

    After more than 25 years working as a chef, I’ve learned that the best knives aren’t always the most decorative.

    They’re the ones you instinctively reach for every day because you trust them.

    That’s exactly how I feel about this Kiritsuke Thick Deba.

    It was built to work.

    It was built to last.

    And above all, it was built to carry forward a legacy that has endured for more than four centuries.

    Some knives are designed simply to cut.

    Others carry the story of generations.

    This 180mm Santoku Aogami #2 Green Micarta Handle with Turquoise Spacer is one of those rare knives that feels like it belongs to both the past and the present.

    When people think about Japanese knives, they often focus on razor-sharp edges, beautiful finishes, or premium steels. Those qualities certainly matter, but I believe the most valuable part of a handcrafted knife is something you cannot immediately see.

    It is the history.

    It is the knowledge passed from one craftsman to another.

    It is the spirit that has survived for centuries.

    That is exactly what I see every time I hold this Santoku.

    A Tradition Forged During the Samurai Era


    Handcrafted farming tools from Tosa

    The story of Tosa knives begins more than 400 years ago, during Japan’s Sengoku period.

    According to the history shared by Ishizuchi Kanamono Manufacturing, the roots of Tosa blacksmithing can be traced back to the rule of the Chōsokabe Clan, who unified Tosa Province in the late 1500s. Historical records mention that nearly 400 blacksmiths were already working throughout the region.

    As Tosa became one of Japan’s leading forestry areas, local craftsmen produced axes, hatchets, sickles, and countless agricultural tools needed for everyday life.

    The techniques required to create tools that could survive years of demanding work eventually evolved into the craftsmanship used to forge kitchen knives.

    Those same forging methods, refined over hundreds of years, are still alive today.

    Every handcrafted Tosa knife represents generations of practical knowledge rather than simply modern manufacturing.

    That heritage is one of the reasons I became fascinated by Tosa knives.

    A Knife That Respects Tradition

    carbon steels

    This Santoku stays true to those traditional roots.

    Its core steel is Aogami #2 (Blue Steel No.2), one of Japan’s most respected carbon steels.

    Professional chefs have trusted Aogami steels for decades because they offer outstanding sharpness, excellent edge retention, impressive toughness, and are surprisingly enjoyable to sharpen.

    Rather than feeling disposable, Aogami #2 develops character over time.

    With proper care, the edge becomes familiar.

    The sharpening becomes rewarding.

    The knife slowly becomes your own.

    That is something mass-produced knives rarely offer.

    A Modern Interpretation of Wabi-Sabi

    Green Micarta handle turquoise space

    While the blade reflects centuries of tradition, the handle introduces something refreshingly modern.

    The Green Micarta handle provides outstanding durability, excellent grip, and stability in busy kitchens.

    Between the blade and the handle sits a beautiful turquoise spacer.

    It is only a small detail.

    Yet it completely changes the personality of the knife.

    Instead of making the knife flashy, it creates a quiet contrast between traditional Japanese craftsmanship and contemporary materials.

    To me, that perfectly reflects the Japanese idea of wabi-sabi.

    Wabi-sabi is not about perfection.

    It is about appreciating balance.

    It is about respecting simplicity.

    It is about finding beauty that grows naturally with time.

    The carbon steel blade will slowly develop its own patina.

    The handle will gain its own character.

    Years from now, this knife will not look exactly as it does today.

    It will look even better because it will tell your own story.

    Why This Knife Impressed Me

    Wabi-Sabi

    I worked as a professional chef for more than 25 years.

    During that time, I have used knives from many famous makers, worked with numerous steels, and sharpened countless blades.

    Because of that experience, I have become difficult to impress.

    Many knives perform well.

    Many knives look beautiful.

    Very few make me stop and think,

    “This is something special.”

    This Santoku did.

    The balance feels natural.

    The blade has confidence without feeling heavy.

    The cutting performance is exactly what I expect from quality Aogami #2 steel.

    At the same time, every detail feels intentional.

    Nothing appears to have been added simply for decoration.

    Everything serves a purpose.

    As a chef, I appreciate that.

    As someone introducing authentic Japanese knives to Australia, I respect it even more.

    More Than Just a Kitchen Tool

    Monozukuri

    One reason I started Asaoya Yaichi was because I wanted people outside Japan to experience authentic craftsmanship rather than simply buying another factory-made knife.

    Many knives today are designed around efficiency.

    Tosa knives are different.

    They are built around craftsmanship.

    Every hammer mark.

    Every grind.

    Every sharpened edge.

    Every handle fitting.

    They all reflect the experience of skilled craftsmen who continue techniques handed down over generations.

    That is becoming increasingly rare.

    When you purchase a handcrafted Tosa knife, you are supporting more than a product.

    You are helping preserve one of Japan’s traditional crafts.

    You are supporting craftsmen whose knowledge has survived since the age of the samurai.

    The Spirit of Tosa Lives On

    Chōsokabe Clan

    Whenever I hold this Santoku, I cannot help but think about the generations of blacksmiths who came before.

    From agricultural tools forged during the time of the Chōsokabe Clan…

    To the exceptional kitchen knives produced today…

    The philosophy has remained remarkably consistent.

    Build tools that work.

    Build tools that last.

    Build tools that people will be proud to use every day.

    That is exactly what this knife represents.

    The 180mm Santoku Aogami #2 Green Micarta Handle with Turquoise Spacer is not simply a beautiful Japanese knife.

    It is the meeting point of over four centuries of Tosa blacksmithing, premium Aogami #2 steel, modern craftsmanship, and the quiet beauty of wabi-sabi.

    After more than twenty-five years as a chef, I can honestly say that knives like this do not appear very often.

    If you are searching for an authentic handcrafted Japanese knife that carries genuine history, exceptional cutting performance, and timeless design, I believe this Santoku is one of the finest examples of Tosa craftsmanship available today.

    It is more than a knife.

    It is a small piece of Japanese history that can be used, appreciated, and passed down for generations.
