The moment when iron and steel become one. Precision in temperature brings forth master craftsmanship
Forging iron to steel is all about perfecting the temperature. Raise it too high, and the structure weakens; too low, and they won’t bind. Every day, I proceed with utmost care, guided by the heat.
Why Are There So Many Types of Japanese Knives?
-
I once heard a foreign chef mutter this in awe as they stood before a Japanese knife display:
“This feels more like a museum of blades than a shop!”Names like Yanagiba, Deba, and Usuba may sound unfamiliar, and their varied shapes can leave even seasoned cooks puzzled. But there’s a solid reason behind this seemingly overwhelming variety.
The sheer number of Japanese knife types exists because Japanese cuisine is rooted in a culture that places extraordinary value on the act of cutting.
-
A Philosophy That Says: “Cut First, Then Cook”
There is a traditional Japanese culinary philosophy known as “Kasshu Hōjū” (割主烹従)—which literally means, “Cutting takes precedence; cooking follows.”
In other words, the key to delicious food lies not in fire or seasoning, but in how it is cut. This is especially true in dishes like sashimi or decorative garnishes, where ingredients are served raw and untouched by heat.
In this context, the knife is not just a tool—it is the primary means of expressing the flavor, texture, and beauty of ingredients. The cut defines the dish, and mastering the blade defines the chef.
-
The Same Ingredient, A Different World—Just by the Knife
Take sashimi, for example. When sliced with a Yanagiba knife using a smooth, pulling motion, it delivers an impossibly silky texture that almost melts on the tongue.
In contrast, using a dull or unsuitable knife crushes the flesh, squeezing out moisture and dulling both taste and appearance.
Even something as simple as shredded daikon radish—called tsuma—depends on the knife. When cut with a Usuba knife, the strands remain crisp, fresh, and almost translucent.
There’s even a Japanese saying: “A beautifully cut daikon garnish is a dish in itself.”In Japanese cuisine, cutting is not just preparation—it is technique, it is expression, it is art.

Western vs. Japanese Cooking: Why Knife Culture Diverged
In Western cuisine, flavor is often developed through heat-based techniques like roasting or saucing. As a result, the way something is cut has less direct impact on taste or texture.
One general-purpose chef’s knife can often handle meats, fish, and vegetables alike.
But in Japanese cuisine, cutting is inseparable from the finished flavor. That’s why specialized knives were developed: a Deba for breaking down whole fish, a Yanagiba for slicing sashimi, and a Usuba for precision vegetable work.
The knife must suit the task, because the cut defines the outcome.

Where Tools Become Art—The Beauty of the Japanese Knife
Each Japanese knife is designed not just for function, but for peak precision and purpose.
・Yanagiba / Takobiki: For long, clean sashimi slices that preserve the fish’s structure
・Usuba: For delicate vegetable cuts like katsuramuki (rotary peeling)
・Deba: For cutting through fish bones without crushing the fleshThese knives are not just tools—they are functional works of art.
Everything from blade thickness and bevel angle to balance and handle design is fine-tuned to suit a specific culinary role.What’s more, professional chefs in Japan sharpen their own knives, adjusting them to match their personal grip and cutting style. Over time, the knife becomes an extension of the chef’s hand—a reflection of their discipline and craft.
-
In Conclusion: The Passion Behind the Variety
So why are there so many types of Japanese knives?
Because Japanese cuisine is built on the belief that how you cut an ingredient determines how it will taste.
Each knife was born from the desire to bring out the best in every ingredient, through the most appropriate and respectful cut.In Japan, a knife is not just a utensil—it’s a tool of expression, a symbol of respect for food, and a reflection of a centuries-old culinary philosophy.
The diversity of Japanese knives is a testament to a culture where “cutting” is not a means to an end—it is the beginning of everything.
FAQ About Type of Japanese Knife

01. Why are Japanese knives more expensive than Western knives?
Japanese knives are more than just kitchen tools—they are handcrafted works of precision, forged with a philosophy of quality over speed. Their higher price reflects three key factors:
1. Traditional Craftsmanship
Every Japanese knife is made through a labor-intensive process involving forging, heat treatment, and meticulous sharpening—all performed by highly skilled artisans. This attention to detail ensures a razor-sharp blade and lasting performance.
2. Premium Materials
Japanese knives often use rare, high-carbon steels such as White Steel (Shirogami) or Blue Steel (Aogami), known for their hardness and ability to hold an edge. These materials are costly and require great skill to work with.
3. Specialization
In Japanese culinary culture, each ingredient deserves the right blade. From Deba for breaking down fish to Yanagiba for slicing sashimi, the wide variety of knives adds both complexity and value.
In short, the price of a Japanese knife reflects its heritage, materials, and the artisan’s hands that bring it to life—a worthy investment for those who value performance and tradition.
02. Why do Japanese chefs use different knives for different ingredients?
Japanese knives, or Wa-bōchō, are designed with a purpose: to respect the integrity of each ingredient. In Japanese cuisine, precision matters—and using the correct knife ensures clean, exact cuts that preserve flavor, texture, and appearance.
For example, a Deba knife can powerfully cut through fish bones without damaging the flesh, while a Yanagiba glides through raw fish for silky sashimi slices. A Usuba knife is ideal for vegetables, delivering paper-thin cuts with almost no resistance.
Using the right knife not only enhances the dish, but also improves workflow and reduces preparation time. It is a culinary philosophy—refining both the cooking and the eating experience.
03. What makes Japanese knives exceptional in quality and performance?
Japanese knives are renowned for their balance of elegance and efficiency. Three elements define their superiority:
Thinness – Their fine-edged blades allow for incredibly precise cuts.
Hardness – Harder steel ensures durability and long-lasting sharpness.
Sharpness – The edge is honed to a level that enables effortless slicing.
Combined, these features make Japanese knives not only functional but also a joy to use—refined tools born of centuries-old techniques.
04. How are Japanese knives different from Western-style knives?
The main difference lies in blade geometry and intended use:
Japanese Knives
・Usually single-beveled, sharpened on one side only.
・Offer high precision, making them ideal for slicing and fine work.
・Examples: Yanagiba, Deba, Usuba.
・Often lighter, with balance toward the handle.
Western Knives
・Double-beveled, sharpened on both sides.
・More versatile and forgiving; suited for chopping and general prep.
・Examples: Chef’s Knife, Paring Knife.
・Tend to be heavier and blade-forward in balance.
Choosing between the two depends on your cooking style. Japanese knives reward technique and control, while Western knives favor versatility and speed.

Type of Handle
Traditional Japanese knife handles, orwa-handles, blend craftsmanship with performance. Lightweight and ergonomically designed, they offer exceptional control and comfort. Choosing the right handle is just as important as choosing the blade—it completes the harmony between hand and tool.

The Origin of Craftsmanship

The Spirit of the Craftsman in Japanese Knives – The Beauty and Mastery of Traditional Blades
Japanese knives are not merely kitchen tools; they are the backbone of culinary art, embodying the soul of cooking. Each type of knife—be it the usuba, yanagiba, or deba—has a unique purpose, and its design and characteristics are the culmination of deep thought and exceptional craftsmanship. As artisans, we pour our hearts into every blade, hoping that chefs will feel that passion when the knife rests in their hands.
-
Take, for example, the usuba knife. It is crafted specifically to handle vegetables with precision and grace. Tasks like katsuramuki (thin slicing of daikon radish) test the chef's skill, and this knife’s sharpness and balance make all the difference. However, mastery requires care; maintaining the blade’s edge is essential. When properly tended to, the usuba knife elevates the quality of any dish, transforming ingredients into culinary art.
-
The yanagiba knife, on the other hand, is designed for sashimi, not to “cut” but to “pull through” the fish. This subtle yet deliberate motion enhances the fish’s natural luster and texture. The shape and material of the yanagiba knife reflect our commitment to empowering chefs to showcase their expertise. Regional variations, such as the Kanto and Kansai styles, highlight Japan’s diverse culinary traditions and regional pride.
-
Finally, the deba knife is a robust partner for filleting fish, with its thick blade and solid weight enabling clean cuts through bones while preserving the delicate flesh. When crafting a deba knife, we imagine the chef at work, facing their ingredients with focus and determination. This connection drives us to create tools that support their artistry.
-
Japanese knives are where the craftsman’s skill and the chef’s artistry converge, enabling the creation of extraordinary dishes. Their precision and complexity are a testament to the depth of Japanese cuisine and the bond between a craftsman and their tools. We hope that every slice, cut, and pull with a Japanese knife resonates with this shared dedication.
-
Beware of Inexpensive Knives
Inexpensive knives are often made with cost-cutting measures during production. Specifically, important elements such as sharpness, balance, and maintainability—key factors that directly affect quality—are not given sufficient investment. These aspects are often difficult to notice at first glance, but they can significantly impact the performance of the knife.
