  • 土佐 Tosa | The Powerful History of Tosa Knives I Wanted to Know

    土佐 Tosa | The Powerful History of Tosa Knives I Wanted to Know

    When you work with something every day, sometimes you forget to ask where it actually came from.

    I sell Tosa knives in Australia, sourcing handcrafted Japanese knives directly from Shikoku, Japan. I have also spent more than 25 years working as a chef in Japan and Australia. I know how these knives feel in the hand, how they sharpen, and how they perform in a professional kitchen.

    But recently, I realised there was something I wanted to understand better.

    How did Tosa knives actually begin?

    I knew that Tosa had a long history of blacksmithing, but I wanted to look deeper into why this particular part of Japan became known for forged blades. What I found made me appreciate the history behind these knives even more.

    The History of Tosa Knives Goes Back Centuries

    Ishizuchi Kanamono Manufactory

    The story of Tosa knives is closely connected to the geography and working life of Kochi Prefecture, historically known as Tosa Province.

    Kochi is a mountainous region with extensive forests. For generations, forestry was an important part of life there, and people needed strong, dependable tools for cutting trees, clearing land and working in the mountains.

    That naturally created demand for forged tools such as axes, hatchets, sickles and saws.

    The history, however, goes back even further.

    Sword-making techniques are said to have reached Tosa during the Kamakura period. By 1590, the Chōsokabe Land Survey Records documented 399 blacksmiths in Tosa Province.

    That number surprised me.

    It shows that blacksmithing was already deeply established in the region more than 400 years ago.

    How Tosa Knives Grew With Forestry and Agriculture


    From Agricultural Tools to Tosa Knives

    The major development of Tosa forged blades came during the early Edo period.

    In 1621, reforms by the Tosa Domain encouraged the development of forestry and new agricultural land. As forestry and farming expanded, so did the need for reliable cutting tools.

    Blacksmiths responded to that demand.

    Over time, production increased and techniques improved. What began as tools essential for daily work gradually developed into what we now recognise as the tradition of Tosa Uchihamono, or Tosa forged blades.

    This is one thing I find particularly interesting about Tosa.

    The tradition was not created simply to make beautiful objects.

    These were working tools.

    They had to cut. They had to survive hard use. And they had to be practical enough for people who depended on them for their livelihood.

    Tosa Knives and the Tradition of Free Forging


    Kiritsuke Aogami #2 Kurouchi Walnut Octagonal Handle

    Another characteristic that caught my attention while researching Tosa knives was something known as jiyū tanzō, or “free forging.”

    Rather than relying entirely on fixed moulds, Tosa blacksmiths traditionally forged different shapes and sizes according to their intended purpose.

    That flexibility made sense in a region where people needed many different kinds of blades for forestry, agriculture and everyday life.

    Even today, you can see something of that character in handcrafted Japanese knives.

    Small differences in hammer marks, blade shape and finish are not necessarily imperfections. To me, they are reminders that a knife was made by human hands rather than simply coming from an automated production line.

    From Traditional Tosa Blades to Modern Kitchen Knives

    Today, Tosa knives are known far beyond Kochi.

    In 1998, Tosa Uchihamono was officially designated as a Traditional Craft of Japan. The tradition includes not only kitchen knives but also axes, sickles, hatchets, saws and other working blades.

    Modern Japanese kitchen knives have naturally evolved as well.

    Today we can find traditional carbon steels such as Aogami alongside stainless steels and modern powder metallurgy steels. Handles, finishes and blade styles have changed to suit contemporary cooks, but the connection between Japanese knife making and traditional forging remains.

    👉 INTERNAL LINK: Learn more about Aogami and Shirogami steels

    👉 INTERNAL LINK: Read my guide to Ginsan steel and why I like it for kitchen knives

    For me, that combination is what makes the history of Tosa so interesting.

    It is not simply a tradition frozen in the past.

    It has continued to evolve.

    Why the History of Tosa Knives Matters to Me


    Wooden Box for Traditional Knives

    After looking into this history, I see the knives I work with a little differently.

    I started Asaoya Yaichi because I wanted to bring genuine handcrafted Japanese knives from Shikoku to Australia. As a chef, my first concern will always be practical: does the knife actually work well in a kitchen?

    But there is another side to it.

    Learning about Tosa knives reminded me that Japanese blades did not develop only as kitchen tools. Their history is connected to forestry, agriculture, sword-making knowledge and generations of blacksmiths adapting their skills to what people actually needed.

    That history does not automatically make every knife perfect.

    But I think understanding where these traditions came from gives us a better appreciation of why Japanese forged knives are the way they are today.

    Perhaps that is what I like most about the history of Tosa.

    These blades were never meant to exist only behind glass.

    They were made to be used.

    And more than 400 years later, that practical spirit can still be found in the Japanese forging traditions that continue across Shikoku today.

    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.”

    👉 INTERNAL LINK: Hardness 硬度 | 7 Powerful Truths About Japanese Knife HRC That Surprised Even a Chef

    The Japanese Knife That Caught My Eye


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

    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

    Ishizuchi Kanamono Manufactory

    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.

    👉 INTERNAL LINK: 均衡 Kinkō | 7 Powerful Reasons Japanese Knife Balance Matters More Than You Think

    Quality Still Matters


    Ginsan Nashiji Forged Magnolia Octagonal Handle Buffalo Horn Ferrule

    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.

    Sometimes a Japanese Knife Just Speaks to You

    We can talk about steel, hardness and blade geometry all day.

    Those things are important, and I think anyone buying a Japanese knife should understand the basics.

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

    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.

    Now I want it for myself.

    Maybe that is Hitomebore — love at first sight.

    And sometimes, that is all it takes for a Japanese knife to become special.

  • 祭 Matsuri | 100kg of Bluefin Tuna and the Hidden Reality Behind the James St Festival

    祭 Matsuri | 100kg of Bluefin Tuna and the Hidden Reality Behind the James St Festival

    James St Festival

    James St Festival Part 2 continues my behind-the-scenes journey through one of Brisbane’s biggest food festivals. After the tuna cutting show ends, the real work begins as nearly 100kg of bluefin tuna sashimi is prepared using handcrafted Japanese knives.

    When people visit the James St Festival, they remember the atmosphere, the incredible food, and the famous tuna cutting show.

    As a sushi chef working behind the scenes, my memories are very different.

    For me, the real challenge began the moment the applause ended.

    This is Part 2 of my behind-the-scenes journey through one of Brisbane’s biggest food festivals—a day filled with preparation, teamwork, and the Japanese knives I rely on every day.

    James St Festival Tuna Cutting Show Begins

    Blue fin Tuna is

    By late morning, hundreds of visitors had gathered around the stage for one of the festival’s biggest attractions—the bluefin tuna cutting show.

    Two enormous whole bluefin tuna were carefully carried onto the stage. Each fish was so heavy that it took four people to lift it safely.

    Seeing the crowd’s excitement was incredible. For many people, it was probably the first time they had ever seen a whole bluefin tuna up close.

    Ironically, I didn’t get to enjoy the show myself.

    While everyone else watched the demonstration, I had already been assigned to help another section of the kitchen prepare for what would happen next.

    In a professional kitchen, someone always has to stay behind the scenes to keep everything moving.

    James St Festival Gets Even Busier After the Show

    The moment the demonstration finished, large sections of freshly cut bluefin tuna began arriving back in the kitchen.

    From that point on, nobody stopped moving.

    Every chef returned to their station.

    Cut.

    Trim.

    Slice.

    Pack.

    Restock.

    Repeat.

    That rhythm continued for hours.

    Every tray of sashimi that left the kitchen had to be replaced immediately.

    Customers kept lining up, and the bluefin tuna disappeared almost as quickly as we could prepare it.

    There was no time to slow down.

    Every slice had to be clean, consistent, and ready to serve.

    ➡ Internal Link: Sujihiki Knives

    James St Festival Served Nearly 100kg of Bluefin Tuna

    Ishizuchi Sujihiki Knife

    Throughout the day, we prepared and sold nearly 100 kilograms of bluefin tuna as sashimi.

    Watching that amount of premium fish disappear throughout the day was something I’ll never forget.

    Preparing sashimi at that volume requires more than speed.

    It demands consistency, concentration, and respect for every piece of fish.

    Every cut matters.

    Even after hours of continuous slicing, every piece must look as good as the very first one.

    That’s one of the biggest differences between cooking professionally and cooking at home.

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

    James St Festival Depends on Japanese Knives

    Ishizuchi Kanamono Manufactory

    Days like this remind me why I trust handcrafted Japanese knives.

    When you’re slicing fish continuously for hours, a knife becomes much more than a tool.

    It becomes an extension of your hands.

    A well-balanced knife reduces fatigue.

    A razor-sharp edge produces cleaner slices.

    Most of the knives I used that day were handcrafted by Ishizuchi Metalworks in Kochi, Japan.

    Among them was one knife that has been with my family for over 40 years—a Kiya Yanagiba originally passed down from my mother.

    Even after decades of professional use, it continues to perform beautifully.

    To me, that’s what makes a truly great Japanese knife.

    It’s not something you simply own.

    It’s something you can pass on to the next generation.

    ➡ Internal Link: Carbon Steel vs Stainless Steel

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

    James St Festival Is Built on Teamwork

    Visitors usually remember the chef standing behind the counter.

    What they rarely see is the entire team working together behind the scenes.

    While one chef slices tuna, another prepares the display, another packs fresh sashimi, while others replenish stock, clean equipment, and keep every station organised.

    Nobody could manage an event like this alone.

    The smooth service that customers experience is only possible because every member of the team works together toward the same goal.

    That is one of the greatest lessons I take away from every major food festival.

    ➡ Internal Link: James St Festival Part 1 – Before the Crowd Arrived

    James St Festival Ends Quietly

    As the afternoon came to an end, the crowds slowly disappeared.

    Inside the kitchen, we cleaned our knives, washed every workstation, packed away equipment, and finally had a chance to take a breath.

    Only then did the exhaustion begin to sink in.

    For visitors, the James St Festival lasts only a few enjoyable hours.

    For the chefs behind the scenes, those few hours represent an entire day of preparation, concentration, teamwork, and hard work.

    After more than 25 years as a professional chef, experiences like this still remind me why I love this profession.

    Creating memorable experiences for people is always worth the effort.

    Final Thoughts

    This two-part series has been a little different from my usual articles about Japanese knives.

    Instead of focusing only on steel, blade shapes, or craftsmanship, I wanted to share what life really looks like behind the scenes of one of Brisbane’s biggest food festivals.

    Every handcrafted Japanese knife has a story.

    Every chef has a story.

    And every unforgettable meal begins long before the first customer arrives.

    If you enjoyed following my journey through the James St Festival, I invite you to explore more stories about traditional Tosa knives, Japanese craftsmanship, and the tools I trust every day as a professional sushi chef.

    165mm Usuba A8 Hammered Damascus Black & Red Octagonal Handle
    A$430.00

    When people think of beautiful Japanese knives, they often picture polished Damascus blades or traditional wooden handles. While those features certainly have their charm, sometimes it is the combination of colours that leaves the strongest impression.

    That is exactly what makes these Black and Red Japanese Knives so memorable.

    The deep black and vibrant red octagonal handles create a striking contrast that reflects both elegance and strength. Inspired by traditional Japanese aesthetics, these handcrafted knives are designed not only to perform exceptionally in the kitchen but also to become pieces you are proud to display.

    Whether you’re a professional chef or a passionate home cook, these knives offer something special every time you pick them up.

    If you’re looking for authentic handcrafted Japanese knives in Australia, you’ll find our carefully selected collection at Asaoya Yaichi

    Why Black and Red Japanese Knives Stand Out

    Wabi-Sabi

    Japanese craftsmanship has always balanced beauty with practicality.

    Black has long represented sophistication, stability and quiet confidence, while red symbolises passion, celebration and energy. Together they create a timeless contrast that immediately attracts attention without appearing overly flashy.

    These Black and Red Japanese Knives perfectly capture that balance.

    Each knife features a beautiful Damascus blade paired with a carefully finished octagonal handle combining rich black and vibrant red. The result is a knife that looks equally at home in a professional sushi bar, an open restaurant kitchen or a modern family home.

    Unlike mass-produced knives, handcrafted Japanese knives develop a personal connection with their owner. Every scratch tells a story, and every meal prepared becomes part of that journey.

    Two Black and Red Japanese Knives with Different Personalities

    Ishizuchi Kanamono Manufactory

    Although these knives share the same elegant design language, each serves a different purpose in the kitchen.

    165mm Usuba A8 Hammered Damascus

    The 165mm Usuba is designed primarily for vegetables.

    Made from A8 stainless steel, it offers excellent corrosion resistance, toughness and easy maintenance. The hammered Damascus finish not only adds visual depth but also helps reduce food sticking to the blade.

    Whether you’re preparing fine julienne vegetables, decorative garnishes or paper-thin slices, the Usuba provides impressive precision while remaining forgiving for everyday use.

    Its lightweight balance also makes long preparation sessions far more comfortable.

    165mm Santoku A10 Damascus

    The matching 165mm Santoku features A10 stainless steel.

    With its higher carbon content, A10 achieves greater hardness and longer edge retention than A8 while still offering excellent corrosion resistance.

    As an all-purpose Japanese kitchen knife, the Santoku handles vegetables, meat and fish with remarkable ease.

    For many home cooks, this will quickly become the knife they reach for every day.

    Why They Create the Perfect Japanese Knife Set

    Damascus blade

    Each knife is beautiful individually.

    Together, however, they become something truly special.

    The matching black and red handles create a visual harmony rarely found when purchasing knives separately.

    Displayed side by side on a magnetic knife rack, they immediately become a focal point in the kitchen.

    Many customers have recently chosen to purchase both knives together rather than individually.

    It’s easy to understand why.

    The combination creates a complete Japanese knife set that feels intentional, elegant and perfectly balanced.

    The Usuba handles vegetables with incredible precision.

    The Santoku takes care of almost everything else.

    Together they cover most daily kitchen tasks while maintaining a consistent appearance that reflects traditional Japanese craftsmanship.

    Rather than mixing different handle colours and styles, this matching pair creates a professional, coordinated look that many chefs appreciate.

    Forged Legacy | The 165mm Kiritsuke Thick Deba That Carries 400 Years of Tosa Craftsmanship

    Some knives are designed to impress.

    Others are designed to work.


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

    But after spending more than 25 years working as a chef, I’ve come to believe that the best knife isn’t necessarily the one that attracts the most attention.

    It’s the one you enjoy reaching for every single day.

    A knife that feels perfectly balanced in your hand.

    A knife that performs beautifully, looks elegant without being flashy, and quietly earns your trust over time.

    That is the philosophy behind this collection.

    In Japan, there is a word that perfectly expresses this way of thinking.

    What Is Monozukuri?

    Ishizuchi Kanamono Manufactory

    Monozukuri literally means “making things.”

    But its true meaning goes much deeper than manufacturing.

    It represents the dedication of Japanese craftspeople who constantly refine their skills, pay attention to the smallest details, and never compromise on quality.

    For generations, Japanese blacksmiths have passed their knowledge from one craftsman to the next.

    Every knife they create reflects years of experience, patience, and pride in their work.

    Rather than chasing trends, they focus on creating tools that perform beautifully and last for many years.

    That philosophy is exactly what inspired this collection.

    Every knife is designed to honour traditional Japanese craftsmanship while fitting naturally into today’s kitchens.

    Premium VG10 Steel with a Beautiful 67-Layer Damascus Blade


    180mm Santoku VG10 Polished Hammered 67 Layer Damascus Green Handle
    A$380.00

    Every knife in this collection is handcrafted in Japan using VG10 stainless steel and features a beautifully finished 67-layer Damascus blade.

    VG10 has earned its reputation as one of Japan’s most respected stainless steels for good reason.

    It offers outstanding sharpness, excellent edge retention, impressive corrosion resistance, and is much easier to maintain than traditional carbon steel.

    That makes it an excellent choice for both professional chefs and passionate home cooks who want the performance of premium Japanese knives without constantly worrying about rust.

    The Damascus blade isn’t simply there to create a beautiful pattern.

    Each layer reflects the precision and care of Japanese craftsmanship.

    The flowing lines give every knife its own unique character while maintaining the practical performance needed for everyday cooking.

    Beautiful tools shouldn’t stay in a display cabinet.

    They should become part of your daily routine.

    A Contemporary Handle Inspired by Japanese Simplicity


    135mm Petty VG10 Polished Hammered 67 Layer Damascus Green Handle
    A$260.00

    While the blade immediately catches your attention, what truly makes this collection different is the handle.

    Traditional Japanese knives are often fitted with magnolia or walnut handles.

    They’re beautiful and timeless.

    This collection takes a different approach.

    The calm green handle introduces a contemporary style while still respecting the understated beauty that Japanese craftsmanship is known for.

    Rather than competing with the Damascus pattern, it complements it.

    Nothing feels over-designed.

    Nothing feels excessive.

    The balance between blade and handle creates a knife that feels refined, comfortable, and natural in the hand.

    It’s modern without losing its connection to tradition.

    To me, that’s one of the most attractive features of this collection.

    Another Expression of Japanese Beauty

    Wabi-Sabi

    Some time ago, I introduced our Wabi-Sabi collection.

    That series celebrated traditional finishes, natural textures, and the quiet beauty that develops through years of use.

    This collection tells a different story.

    Instead of focusing entirely on traditional appearance, it combines centuries of Japanese blacksmithing with contemporary materials and thoughtful design.

    It’s a different expression of Japanese craftsmanship.

    Neither is better.

    They’re simply different philosophies.

    (Insert your internal blog link here.)

    One embraces the beauty of age and simplicity.

    The other demonstrates how Japanese craftsmanship can continue evolving while respecting its heritage.

    Both represent the spirit of Monozukuri.

    Because Monozukuri isn’t about resisting change.

    It’s about improving with every generation while never losing sight of the craftsmanship that came before.

    Three Knives. One Complete Collection

    Knife Set

    This collection is available in three carefully selected models.

    Santoku

    The Santoku is one of Japan’s most versatile kitchen knives.

    Whether you’re preparing vegetables, slicing meat, or cutting fish, it’s designed to handle everyday cooking with ease.

    Its balanced size makes it an excellent choice for home cooks looking for a single knife that can do almost everything.

    Gyuto

    The Gyuto is Japan’s answer to the Western chef’s knife.

    Its longer blade offers greater versatility when working with larger vegetables, meat, and fish while maintaining the precision that Japanese knives are known for.

    If you enjoy preparing a wide variety of ingredients, the Gyuto quickly becomes one of the most useful knives in the kitchen.

    Petty

    The Petty knife is designed for precision.

    From peeling fruit and vegetables to trimming meat or preparing garnishes, it provides complete control for delicate work that larger knives simply can’t match.

    Although it’s the smallest knife in the collection, many chefs consider it one of the most frequently used.

    Each knife has its own purpose.

    Together, they create a collection capable of handling almost every task in the kitchen.

    Because every knife shares the same premium VG10 steel, beautifully finished 67-layer Damascus blade, and distinctive green handle, they work together not only in performance but also in appearance.

    Why I Recommend Building the Complete Collection

    Many people begin by purchasing a single Japanese knife.

    That’s exactly what I would recommend if you’re just starting your journey.

    However, once you experience the quality of a handcrafted knife, it’s easy to understand why so many people gradually build a complete collection.

    Having the right knife for each task makes cooking smoother, more enjoyable, and more efficient.

    The Santoku becomes your everyday companion.

    The Gyuto handles larger ingredients with confidence.

    The Petty takes care of all the finer details.

    Instead of asking one knife to do every job, each knife performs the task it was designed for.

    As a result, not only does cooking become easier, but your knives also stay in better condition because each blade is used appropriately.

    My Experience After More Than 25 Years as a Chef

    Having worked as a chef for more than 25 years, I’ve noticed something that many people don’t think about until they experience it themselves.

    When your knives all belong to the same collection, people notice.

    In professional kitchens, fellow chefs often comment on how clean and professional a matching set looks.

    It’s not unusual for someone to walk past and say,

    “Those knives look great together.”

    I’ve also spent many years working at sushi counters where customers can clearly see the knives being used.

    Interestingly, customers notice them too.

    I’ve had guests compliment the appearance of a matching set before they’ve even tasted the food.

    Of course, beautiful knives don’t make someone a better chef.

    Skill, experience, and technique will always be far more important.

    But presentation matters.

    Just as chefs take pride in wearing a clean uniform and maintaining an organised workstation, using knives from the same collection creates a sense of consistency and professionalism.

    It reflects the respect we have for our craft.

    That’s one of the reasons I personally enjoy using knives from the same series whenever possible.

    Not because they match.

    But because together they create a workspace that feels organised, intentional, and enjoyable to work in every day.

    For me, that’s another reason why I often recommend building a complete Japanese knife set rather than collecting individual knives from different collections.

    It’s something I’ve genuinely appreciated throughout my career, and I believe many passionate home cooks will appreciate it too.

    More Than Just a Knife

    A yanagiba knife that has been used for 40 years

    After more than 25 years as a chef, I’ve come to realise that a great knife is far more than just a cutting tool.

    It’s something you rely on every day.

    It becomes part of the way you cook, the way you work, and even the way you present yourself as a chef.

    The longer you use a well-made knife, the more you appreciate the skill, experience, and dedication that went into creating it.

    That’s exactly what Monozukuri is all about.

    It’s not simply making products.

    It’s about creating something with care, purpose, and pride—something designed to be used and appreciated for many years.

    Every handcrafted knife in this collection reflects that philosophy.

    The Asaoya Yaichi Philosophy

    Asaoya Yaichi

    At Asaoya Yaichi, our goal has never been to offer the largest selection of Japanese knives.

    Instead, we carefully select knives that we genuinely believe in.

    As someone who has spent over two decades working in professional kitchens, I understand how important it is to trust the tools you use every day.

    That’s why every knife we offer is chosen not only for its appearance, but also for its performance, durability, and the craftsmanship behind it.

    We want to introduce authentic handcrafted Japanese knives that you’ll enjoy using for many years—not simply because they’re beautiful, but because they earn their place in your kitchen every time you cook.

  • Wabi-Sabi | Experience the Quiet Beauty of This Handcrafted Santoku Knife

    Wabi-Sabi | Experience the Quiet Beauty of This Handcrafted Santoku Knife

    Ishizuchi Kanamono Manufactory

    When people think of a beautiful Japanese knife, many imagine a mirror-polished blade or an eye-catching Damascus pattern.

    While those styles certainly have their place, Japanese culture has long embraced a different idea of beauty.

    Rather than seeking perfection, traditional Japanese aesthetics celebrate simplicity, balance, authenticity, and the quiet character that develops over time.

    This philosophy is known as Wabi-Sabi.

    Wabi-Sabi isn’t simply about appearance. It is about appreciating craftsmanship, natural materials, and the beauty that comes from using something every day.


    180mm Santoku VG10N 33 Layer Damascus Green Marble Handle Rainbow Spacer Red
    A$780.00

    For me, the 180mm Santoku VG10N 33 Layer Damascus Green Marble Handle Rainbow Spacer Red perfectly captures that philosophy.

    The flowing 33-layer Damascus pattern is elegant without being overwhelming.

    Instead of demanding attention, it reveals more detail every time the light hits the blade from a different angle.

    The longer you look at it, the more you appreciate its subtle beauty.

    The green marble handle makes every knife unique.

    Because the material naturally varies, no two handles are ever identical.

    Each knife has its own personality, something I believe perfectly reflects the spirit of handcrafted Japanese craftsmanship.

    Between the blade and the handle sits a beautiful rainbow spacer.

    Rather than feeling flashy, it provides a tasteful modern accent that complements the traditional Damascus blade and the elegant green marble handle.

    Together, these elements create a knife that feels refined, balanced, and unmistakably Japanese.

    Asaoya Yaichi

    This series is also available in four different handle colours — Red, Yellow, Orange, and Blue.

    Each colour offers its own distinctive personality while maintaining the same exceptional craftsmanship and cutting performance.

    Whether you prefer something bold or something more understated, there is a version that will suit your own style and kitchen.

    There is also something very special about this collection that I’d like to share.

    I was recently told that, due to personal circumstances, the blacksmith responsible for producing these knives may not be creating new designs in the future.

    Nothing has been officially confirmed, and of course everyone hopes that new creations will continue.

    However, there is a genuine possibility that this collection could become one of the final series produced by this craftsman.

    If that turns out to be the case, these knives will represent far more than beautiful kitchen tools.

    They will become lasting examples of one artisan’s work and dedication.

    To me, that adds another layer of meaning to owning one.

    Not because it might become rare, but because it carries the story of a craftsman whose work deserves to be appreciated.

    Of course, beauty alone isn’t enough.

    A great knife must also perform exceptionally well.

    VG10 Stainless Steel

    This Santoku is forged from VG10N stainless steel, one of Japan’s most respected stainless steels.

    It offers excellent edge retention, impressive corrosion resistance, and straightforward maintenance, making it an excellent choice for both professional chefs and passionate home cooks.

    If you’ve always admired handcrafted Japanese knives but felt hesitant about maintaining carbon steel, VG10N offers an ideal balance between performance and convenience.

    The 180mm Santoku is also one of the most versatile knives you can own.

    From vegetables and meat to fish and everyday meal preparation, it handles almost every kitchen task with confidence.

    It is no surprise that Santoku has become one of the world’s most popular Japanese knife styles.

    Having worked as a chef for more than 25 years, I’ve handled countless Japanese knives.

    Some impress immediately with extravagant finishes.

    Others focus purely on performance.

    But the knives that remain with you for years are usually the ones you naturally reach for every single day.

    This Santoku feels exactly like that.

    Beautiful without trying too hard.

    Elegant without being fragile.

    Practical enough for everyday cooking while carrying the soul of traditional Japanese craftsmanship.

    Perhaps that is the true meaning of Wabi-Sabi.

    Finding beauty not in perfection, but in honest craftsmanship, thoughtful design, and an object that becomes more meaningful every time you use it.

    If you’re looking for a handcrafted Japanese knife that combines timeless beauty, exceptional performance, and the possibility of becoming part of a very special chapter in a Japanese craftsman’s story, this Santoku deserves a place in your kitchen.

  • Japanese Knife Handles: Why the Handle Matters More Than You Think

    Japanese Knife Handles: Why the Handle Matters More Than You Think

    Ishizuchi Kanamono Manufactory

    When people choose a Japanese knife, they usually focus on the blade.

    Should it be carbon steel or stainless steel?
    VG10 or Aogami #2?
    Gyuto or Santoku?

    Those are all important questions—but after more than 25 years working as a chef, I’ve learned that the handle is just as important as the blade.

    A knife can have incredible steel, but if it doesn’t feel comfortable in your hand, you’ll never enjoy using it.

    The Handle Changes How a Knife Feels

    Many people assume the handle is simply there to hold the knife.

    In reality, it affects:

    • Balance
    • Overall weight
    • Grip comfort
    • Fatigue during long prep sessions
    • Control for fine cuts

    These are things you notice more and more the longer you use a knife.

    Personally, I generally prefer lightweight natural wooden handles.

    A lighter handle makes the knife feel more agile, especially during long hours of preparation.

    Natural wood also develops its own character over time, making each knife feel unique.

    Different Woods, Different Feel

    Ishizuchi Kanamono Seisakusho

    One thing I found particularly interesting when visiting Ishizuchi Kanamono Seisakusho was the variety of handles they offer.

    Their standard handle options include:

    • Magnolia (Round)
    • Walnut (Round)
    • Cherry Blossom (Octagonal)
    • Magnolia with Black Buffalo Horn Ferrule (Octagonal)
    • Walnut (Octagonal)
    • Rosewood (Octagonal)

    Each wood has its own appearance, weight, and feel in the hand.

    Even though the blade may be exactly the same, changing the handle can completely change how the knife feels to use.

    The Buffalo Horn Ferrule


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

    One small detail that many people overlook is the buffalo horn ferrule (the black section between the blade and the wooden handle).

    Besides giving the knife a traditional Japanese appearance, it is durable and easy to maintain.

    The only trade-off is that it adds a little extra weight compared to an all-wood handle.

    Personally, I still prefer lighter wooden handles, but I can certainly understand why many people appreciate the buffalo horn option for its durability and premium look.

    There really isn’t a right or wrong choice—it simply depends on what feels best in your hand.

    Tradition Meets Modern Design


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

    While traditional wooden handles remain the most popular choice, they’re not the only option.

    During my visit to Ishizuchi Kanamono Seisakusho, I learned that unique handle materials—including marble—can also be sourced through special orders.

    To me, this is where Japanese craftsmanship becomes truly fascinating.

    A traditional hand-forged Tosa blade paired with a modern marble handle creates something that feels both timeless and contemporary.

    Rather than taking away from tradition, it gives the knife a new expression while preserving the craftsmanship behind the blade.

    I think this beautifully reflects the idea of Wabi-Sabi—respecting tradition while allowing it to evolve.

    A knife like this isn’t simply made to cut.

    It’s a handcrafted tool that can also be appreciated as a work of art.

    Looking for Something Unique?

    Ishizuchi Kanamono Manufactory

    During my visit, I also learned that special handle materials are available through custom orders.

    So if you’re looking for something truly personal or distinctive, there may be more options beyond the standard lineup.

    Custom handles can make a handcrafted Japanese knife even more unique, creating a knife that reflects your own style as well as the craftsmanship behind it.

    My Advice After 25 Years as a Chef

    If you’re buying your first Japanese knife, don’t choose based only on the steel.

    Hold the knife if you can.

    Pay attention to:

    • Weight
    • Balance
    • Shape
    • Handle material

    A knife should feel like a natural extension of your hand.

    Sometimes, changing the handle can make a bigger difference than changing the steel.

  • How Often Should You Really Sharpen a Japanese Knife?

    How Often Should You Really Sharpen a Japanese Knife?

    A Chef’s Honest Perspective


    I use an electric sharpener at home.

    One of the most common questions I hear is:

    “How often should I sharpen my Japanese knife?”

    The answer might surprise you.

    After more than 25 years working as a chef in both Japan and Australia, I’ve learned that there isn’t a single correct answer.

    Every chef develops their own routine based on the knives they use, the ingredients they prepare, and the standards they set for themselves.

    My Routine May Surprise You


    240mm Thick Deba Aogami #2 Kurouchi Walnut Handle

    To be completely honest, I don’t fully sharpen my knives every day.

    In my own routine, I usually do a proper sharpening on a 1000-grit whetstone about once a week.

    During service, if I feel the edge beginning to lose its bite, I’ll often touch it up lightly on a 6000-grit finishing stone to keep the knife performing consistently until my next full sharpening.

    That approach has worked well for me throughout many years in professional kitchens.

    Every Chef Is Different


    A Chef’s Daily-Cared-For Knife

    At the same time, I’ve worked alongside chefs whose approach is completely different.

    Some sharpen their knives every single day.

    Some go even further, polishing their blades with mirror-polishing compounds until they achieve an incredibly refined finish.

    When you use one of those knives, the difference can be astonishing.

    I’ve borrowed colleagues’ knives before and genuinely thought,

    “Wow… this thing is unbelievably sharp.”

    Those moments remind me that there is always something new to learn.

    I’m Still Learning Too

    People sometimes assume that because I’ve been a chef for over 25 years, I must be a master sharpener.

    The truth is, I don’t see myself that way.

    There are many chefs whose sharpening skills are better than mine, and I’m perfectly happy to admit that.

    Sharpening is a craft in itself.

    Like cooking, it’s something you can continue improving for a lifetime.

    I believe being honest about that is more valuable than pretending to know everything.

    The Goal Isn’t Perfection

    Otori,Scallop,Scampi Sashimi

    For professional chefs, the goal isn’t always creating the sharpest knife imaginable.

    The real goal is having a knife that performs reliably, safely, and consistently throughout service.

    For home cooks, the standard is even simpler.

    You don’t need to sharpen your knife every week just because a professional chef does.

    If your knife still cuts cleanly and feels comfortable to use, it’s probably doing exactly what you need.

    Listen to Your Knife

    Instead of following someone else’s schedule, learn to pay attention to your knife.

    Is it crushing tomatoes instead of slicing them?

    Does it slip instead of biting into ingredients?

    Does it require more pressure than it used to?

    Those are much better indicators than the calendar.

    Every knife tells you when it’s time.

    You simply have to learn how to listen.

    A Final Thought


    When I’m not in the kitchen, I’m probably squid fishing.

    One lesson I’ve learned throughout my career is that there is no single “correct” way to care for a Japanese knife.

    Different chefs have different routines.

    Different kitchens have different demands.

    What matters most is finding a routine that keeps your knife performing well and encourages you to enjoy using it.

    A well-maintained Japanese knife isn’t about chasing perfection.

    It’s about building a relationship with a tool that can serve you for many years.

    Looking for a Japanese knife worth caring for?

    At Asaoya Yaichi, we carefully select authentic handcrafted Tosa knives made by skilled Japanese blacksmiths.

    Whether you’re buying your first Japanese knife or adding to an existing collection, our goal is to help you find a knife you’ll enjoy using—and maintaining—for years to come.

  • A Knife That Earned My Respect

    A Knife That Earned My Respect

    Part 2 – A Knife That Grows With You

    Knife Care

    The more I used traditional Tosa knives, the more I realised something.

    The blacksmith’s work doesn’t end when the knife leaves the forge.

    In many ways, that’s where the next chapter begins.

    A handcrafted knife is not meant to remain exactly as it was on the day it was made.

    It is meant to grow alongside the person who uses it.

    That may sound unusual at first.

    But after spending more than twenty-five years working as a chef, I have come to believe it is true.

    A Knife That Learns Your Hands


    A Knife That Learns Your Hands

    Every chef works differently.

    Some prefer a finer edge for delicate slicing.

    Others leave a little more strength behind the edge for heavier work.

    Some sharpen frequently.

    Others wait until the knife tells them it is time.

    None of these approaches are necessarily right or wrong.

    Over time, every sharpening subtly changes the knife.

    Every service leaves another memory.

    Every meal adds another chapter.

    Eventually, something remarkable happens.

    The knife no longer feels like a tool made by someone else.

    It feels like your knife.

    That is why I often say a great knife isn’t finished by the blacksmith alone.

    The blacksmith begins the story.

    The owner completes it.

    Beauty Beyond Perfection


    240mm Thick Deba Aogami #2 Kurouchi Walnut Handl

    When many people imagine a premium Japanese knife, they picture a flawless mirror finish.

    I used to think the same way.

    Today, I see beauty differently.

    A softened Kurouchi finish.

    A natural patina on carbon steel.

    Small marks left behind after years of careful sharpening.

    These are not imperfections.

    They are evidence of a knife that has been trusted.

    To me, that is a far more meaningful kind of beauty.

    It reminds me of the Japanese philosophy often described as Wabi-Sabi—finding beauty in authenticity, simplicity and the passage of time.

    The character of a handcrafted knife is not frozen on the day it is forged.

    It continues to evolve with every meal it helps create.

    Different Regions, Different Traditions


    150mm Kiritsuke Thick Deba Aogami #2 Kurouchi Walnut Octagonal Handle

    Japan is home to many extraordinary knife-making regions.

    Sakai is renowned for its precision and refined finishing.

    Kyoto is admired for its elegance and long tradition of craftsmanship.

    I have enormous respect for both.

    Tosa simply tells a different story.

    Its blacksmiths were shaped by a region where tools were expected to work hard every single day.

    Generations of craftsmen forged tools for farming, forestry and fishing long before they became known for kitchen knives.

    That heritage is still visible today.

    A Tosa knife doesn’t try to hide where it came from.

    Its forged texture, Kurouchi finish and practical design proudly reflect its working roots.

    That is exactly what many people come to appreciate.

    Some collectors are captivated by the refined elegance of Sakai or Kyoto.

    Others are drawn to the rugged honesty of Tosa.

    Many enjoy collecting knives from different regions because each one tells a different story about Japan’s remarkable craft traditions.

    It isn’t about deciding which is better.

    It is about appreciating the unique character each tradition offers.

    Why Asaoya Yaichi Exists

    Ishizuchi Kanamono Manufactory

    People sometimes ask why I decided to start Asaoya Yaichi.

    The answer is simple.

    I wanted to introduce Australians to authentic handcrafted Tosa knives.

    Not because they are fashionable.

    Not because they are the most expensive.

    But because I believe they deserve to be recognised for what they truly are.

    For too long, I have seen mass-produced knives marketed as “Japanese knives” without representing the traditions that made Japanese craftsmanship respected around the world.

    That isn’t what I wanted to share.

    I wanted to introduce knives with a genuine story.

    Knives made by skilled blacksmiths whose techniques have been handed down through generations.

    Knives that improve with care instead of losing their value.

    Knives that can still be used decades from now—just like the Yanagiba my mother used for around twenty years before passing it on to me, and that I’ve continued using for another twenty.

    That knife reminds me that a truly great knife isn’t measured by how it looks on the first day.

    It’s measured by how faithfully it serves over a lifetime.

    More Than Selling Knives

    Working with Ishizuchi Kanamono Seisakusho has strengthened that belief.

    For more than a century, they have remained committed to supporting authentic craftsmanship and the people behind it.

    That philosophy reflects exactly what I hope Asaoya Yaichi can become.

    Not simply a shop.

    But a bridge.

    A bridge between the traditional blacksmiths of Tosa and the people who will use their work every day here in Australia.

    Every knife carries the skill of the craftsman who forged it.

    But its future belongs to the person who chooses to use it.

    That relationship is what makes handcrafted knives so special.

    A Final Thought

    If there is one lesson I have learned after more than twenty-five years as a chef, it is this:

    The best knife is not always the one that impresses you on the first day.

    Sometimes, the best knife is the one that quietly earns your respect over many years.

    That is exactly what happened to me.

    I didn’t fall in love with Tosa knives the moment I first picked one up.

    I fell in love with them after cooking with them.

    After sharpening them.

    After trusting them.

    That journey changed the way I looked at knives forever.

    It is also the reason Asaoya Yaichi exists today.

    If you’ve always believed traditional Japanese knives are difficult to maintain, you may be surprised.

    With a little knowledge and regular care, a handcrafted knife can stay with you for decades.

    In future articles, I’ll be sharing practical knife care, sharpening techniques, and maintenance tips to help you get the very best from your knife—whether you’re a professional chef or cooking at home.

    If this article encourages even one person to look beyond appearances and discover the craftsmanship, history and spirit behind a traditional Tosa knife, then I believe I have achieved something meaningful.

    Because we are not simply preserving knives.

    We are helping preserve the people, the skills and the traditions that continue to shape them.

  • A Knife That Earned My Respect

    A Knife That Earned My Respect

    Why I Chose Tosa Knives


    165mm Kiritsuke Aogami #2 Kurouchi Walnut Octagonal Handle

    I’ll be honest.

    The first time I held a traditional Tosa knife, I wasn’t impressed.

    At that stage of my career, I believed the best Japanese knives had to look a certain way.

    Mirror-polished.

    Beautifully finished.

    Elegant.

    To me, that was what a premium knife looked like.

    Then I picked up a traditional Kurouchi Tosa knife.

    It felt different.

    It looked different.

    If I’m being completely honest, I didn’t really like it.

    It seemed rough.

    Almost unfinished.

    I couldn’t understand why so many people respected it

    Looking back now, I realise the knife wasn’t the problem.

    I simply hadn’t lived with it long enough.

    Twenty-Five Years Behind the Knife

    @Asaoya_yaichi

    For more than twenty-five years, I worked as a chef in both Japan and Australia.

    Except for my days off, I spent almost every day with a knife in my hand.

    Preparing fish.

    Breaking down ingredients.

    Serving customers who expected consistency every single service.

    A professional kitchen teaches you something that catalogues and advertisements never can.

    A knife isn’t judged by how beautiful it looks when it’s new.

    It’s judged by how it performs after years of work.

    After thousands of sharpenings.

    After countless services.

    After becoming part of your own hands.

    The Knife That Taught Me This Lesson


    A 40-Year-Old Yanagiba Knife My Mother Passed Down to Me

    The most valuable knife I own isn’t the newest.

    It isn’t the most expensive.

    It’s a Yanagiba that belonged to my mother.

    She loved cooking, and she cared for that knife for decades.

    Today, around forty years after it first entered our family, I still use it.

    Every time I sharpen it, I’m reminded that a great knife isn’t something you simply buy.

    It’s something you build a relationship with.

    Every sharpening changes it.

    Every meal leaves a memory.

    Every year gives it more character.

    The knife I use today is no longer exactly the knife my mother once held.

    It has become part of both our stories.

    That is something money cannot buy.

    Discovering Tosa Again

    Years later, something unexpected happened.

    My brother-in-law had a close relationship with Ishizuchi Kanamono Seisakusho.

    Through that connection, I received several sample knives.

    At first, I didn’t expect much.

    After all, my first impression of traditional Tosa knives had never been particularly strong.

    But I decided to use them.

    Not for a day.

    Not for a week.

    I used them in the way a chef truly tests a knife.

    Day after day.

    Service after service.

    Sharpening them.

    Maintaining them.

    Learning them.

    Slowly, my opinion began to change.

    What I had once mistaken for roughness turned out to be honesty.

    What I had once considered simple became incredibly practical.

    The knife wasn’t trying to impress me on the first day.

    It was asking me to discover it over time.

    That is when I truly began to understand Tosa knives.

    More Than a Supplier

    Ishizuchi Kanamono Manufactory

    As I learned more about Ishizuchi Kanamono Seisakusho, I realised that their story reflected the very philosophy I had begun to appreciate.

    Their history dates back more than one hundred years to the early Taisho era, when the company began as Ishizuchi Agricultural Machinery.

    Its purpose was simple: to provide dependable tools for people whose livelihoods depended on them.

    Farmers.

    Foresters.

    Fishermen.

    People who worked with their hands every day.

    As Japan changed, so did the company.

    Today, Ishizuchi Kanamono Seisakusho works alongside traditional Tosa blacksmiths, helping preserve generations of craftsmanship while introducing authentic Tosa knives to people around the world.

    That story resonated deeply with me.

    These knives were never created simply to impress someone in a showroom.

    They were created to be used.

    Maintained.

    Sharpened.

    Trusted.

    Perhaps that is why my opinion changed so dramatically.

    I had been judging these knives by how they looked.

    Instead, I should have judged them by how they lived.

    That simple realisation changed the way I looked at Tosa knives forever.

    It is also the reason Asaoya Yaichi exists today.

    Not simply to sell handcrafted knives.

    But to introduce the people, traditions and craftsmanship behind every blade, ensuring that the remarkable spirit of Tosa continues to be appreciated by future generations.

    In Part 2 – A Knife That Grows With You, I’ll share why I believe the finest handcrafted knives are never truly finished when they leave the blacksmith, but continue to grow alongside the people who use them.

  • Wabi-Sabi Vibes: A Rare Japanese Santoku Knife Where Tradition Meets Modern Design

    Wabi-Sabi Vibes: A Rare Japanese Santoku Knife Where Tradition Meets Modern Design

    Introduction

    When I first saw this knife, one thought immediately came to mind.

    “What an unexpected combination.”

    A beautifully traditional Japanese Damascus blade paired with a bold marble-style handle that feels almost like modern art.

    At first, it shouldn’t work.

    Yet somehow, it does.

    The more I looked at it, the more one phrase stayed in my mind:

    Wabi-Sabi Vibes.

    What Does Wabi-Sabi Really Mean?

    When people hear the words Wabi-Sabi, they often imagine old temples, quiet tea rooms, weathered wood, or handmade pottery shaped by time.

    Those images certainly represent Wabi-Sabi.

    But to me, Wabi-Sabi is something much deeper.

    It is the appreciation of authenticity over perfection.

    It is seeing beauty in individuality, craftsmanship, and the stories that objects carry.

    Rather than resisting change, Wabi-Sabi embraces the passage of time while respecting tradition.

    That philosophy is deeply connected to handcrafted Japanese knives.

    Every authentic Japanese knife carries the experience of the blacksmith, generations of knowledge, and countless hours of craftsmanship.

    It is far more than simply a kitchen tool.

    A Santoku That Blends Tradition With Modern Design

    The first thing that catches your eye is the blade.

    Elegant Damascus layers.

    A classic Santoku profile.

    Traditional Japanese forging techniques.

    Everything about the blade reflects generations of Japanese craftsmanship.

    Then your attention moves to the handle.

    Instead of walnut or magnolia wood, this knife features a striking marble-style handle with bold contemporary colours.

    It feels modern.

    Confident.

    Almost futuristic.

    Yet surprisingly, nothing feels out of place.

    The traditional blade and contemporary handle complement one another beautifully.

    That harmony between old and new is exactly what makes this knife unforgettable.

    Tradition Doesn’t Mean Standing Still

    Some people believe traditional craftsmanship should never change.

    I respectfully disagree.

    Japanese craftsmanship has survived for centuries because artisans have continued to preserve traditional techniques while embracing new ideas, new materials, and new artistic expressions.

    Respecting tradition does not mean rejecting innovation.

    When traditional forging meets contemporary design, something unique happens.

    The soul remains unchanged.

    The personality evolves.

    For me, that is exactly what Wabi-Sabi Vibes represent.

    A quiet balance between heritage and creativity.

    A Knife That May Never Be Made Again

    Hiro Blacksmith

    This Santoku is also special for another reason.

    The blacksmith who creates this series has recently stepped back from regular production due to personal circumstances.

    Because of this, we simply don’t know when—or even if—more of these knives will ever be produced.

    Each knife therefore represents more than exceptional craftsmanship.

    It captures a particular moment in a craftsman’s journey.

    Once these are gone, there is no guarantee another batch will ever become available.

    That rarity makes every piece even more meaningful.

    More Than Just Sharpness

    After more than 25 years working as a chef in both Japan and Australia, I’ve learned that great knives are remembered for more than how well they cut.

    The finest knives have character.

    They have personality.

    They have stories.

    This Santoku brings together a traditional Japanese Damascus blade, an unmistakably modern marble-style handle, and a level of rarity that cannot be manufactured.

    It is not simply another kitchen knife.

    It is a conversation piece.

    A functional work of art.

    A knife that represents both the past and the future of Japanese craftsmanship.

    That is why I call it…

    Wabi-Sabi Vibes.
