The world of culinary cutlery is rich and diverse, with different cultures developing unique styles of knives based on their cooking traditions and techniques. Among the most revered are Japanese knives, known for their exceptional sharpness, fine craftsmanship, and elegant design. If you’ve ever wondered, “What is a Japanese knife called?” you’re not alone. This article explores the terminology, varieties, history, and unique features of Japanese knives to give you a deeper understanding of these culinary masterpieces.
The Terminology: What Is a Japanese Knife Called?
In general, a Japanese knife is referred to as “hocho” (包丁) in the Japanese language. This is a generic term for knives, especially kitchen knives, used in Japanese culinary culture. However, there are many subtypes of knives, each with its own specific purpose and name. Understanding the names of these knives helps one appreciate the depth of Japanese culinary tradition and the specialized design of its cutlery.
Other common names include:
- Yanagiba – A long, slender knife used primarily for slicing raw fish in sashimi preparation.
- Deba – A thick, heavy knife used for filleting fish and other heavy-duty tasks in seafood preparation.
- Usuba – A thin, lightweight vegetable knife used in Japanese kitchens, particularly by professionals.
- nakiri – A double-beveled knife also used for cutting vegetables.
Common Misconceptions About Japanese Knives
Many people refer to Japanese knives simply as “santoku” knives, which is actually just one type of Japanese chef’s knife. While the santoku is among the most famous Japanese knives globally, it doesn’t encompass all types. Understanding the different names helps users choose the right knife for their cooking style.
History and Evolution of Japanese Knives
Japanese knife-making has deep historical roots, influenced by samurai sword craftsmanship and traditional Japanese dietary habits. The evolution of Japanese knives can be traced back more than a thousand years, with much of the modern techniques developed during the Edo period (1603–1868) in cities like Osaka and Seki, which remain prominent centers for knife production today.
Traditionally, Japanese bladesmiths used high-carbon steel (like hagane) for their knives, similar to the steel used in forging katana swords. This gave Japanese knives their hallmark sharpness and edge retention. However, traditional Japanese steel is more brittle compared to modern stainless steel, making it susceptible to chipping if not properly maintained.
Over the centuries, Japanese knife-making evolved to accommodate both Western and Japanese culinary techniques. This fusion led to the development of Western-style Japanese knives, such as the santoku and Gyuto (Japanese chef’s knife). These knives retain the acute edge angles and superior steel quality of traditional Japanese blades while incorporating more ergonomic handles and shapes that appeal to chefs outside of Japan.
The Influence of Regional Traditions
Japanese knife-making centers each developed their own specialties. For example:
- Osaka became known for its sashimi and sushi knives, like the Yanagiba.
- Hirosaki perfected the Deba for fish cutting.
- Kyoto was a hub for vegetables knives like the Usuba.
Even today, these regional distinctions influence the characteristics of Japanese knives found around the world.
Types of Japanese Knives: A Detailed Overview
The diversity of Japanese knives means there is a specific tool for nearly every culinary task. Below is a categorized list of the most common types, along with their uses and features:
1. Chef’s Knives and All-Purpose Blades
Santoku
The term santoku translates to “three virtues” or “three uses,” referring to its ability to chop, slice, and mince. It is shorter and lighter than a Western chef’s knife, making it ideal for precision work. Santoku knives typically have a 15–18 degree edge angle and are often made from stainless steel for easier maintenance.
Gyuto
Also known as the Japanese chef’s knife, the gyuto is the Eastern counterpart to the Western chef’s knife. It is versatile, with a thinner blade that allows for more delicate cuts. Gyuto knives are usually made from high-carbon steel or a composite of harder and softer steels, and they require more maintenance than typical Western knives.
2. Fish and Seafood Specialties
Deba
The Deba bocho is a heavy, thick knife designed for filleting fish. Its weight allows chefs to cleanly cut through small fish bones. Varieties include the ko-deba for smaller fish and the hon-deba for heavier work. Deba knives are typically single-beveled, which means only one side is angled, enhancing cutting precision.
Yanagiba
The Yanagiba is sometimes called the sashimi knife. With a long, thin blade, it is designed for slicing fish in a single, smooth motion. Its length is typically between 9 and 12 inches. This knife is single-edged, like many traditional Japanese blades, and creates ultra-clean cuts that maintain the integrity and presentation of raw fish.
3. Vegetable Knives
Usuba
A traditional veg-specific knife, the Usuba is similar to the Western chef’s knife but lighter and thinner. It features a square tip and is traditionally used in kappo (a style of Japanese dining focused on seasonal ingredients). Usuba knives are also single-beveled and crafted for precision work, such as making thin, uniform slices of vegetables for garnishing or presentation.
Nakiri
The Nakiri differs from the Usuba in that it is double-beveled, making it more user-friendly for Western chefs or home cooks unfamiliar with single-beveled knives. It excels at slicing leafy greens, root vegetables, and softer produce. Its shape is similar to a cleaver, but significantly thinner and sharper.
Design and Features of Japanese Knives
Japanese knives have distinct features that set them apart from Western knives, both in design and performance. These differences are rooted in centuries-old culinary traditions and blade-making techniques.
Steel Quality and Hardness
Most Japanese knives are made from high-carbon steel, which allows for an extremely sharp edge. This results in finer, cleaner cuts. Many modern knives also use stainless steel for easier maintenance and corrosion resistance.
Steel hardness in knives is measured using the Rockwell hardness scale (HRC). Japanese knives typically fall within the 60–64 HRC range, which is harder than Western knives (54–58 HRC). While this gives them superior edge retention, it can also make them more fragile.
Types of Steel Used in Japanese Knives
| Steel Type | Description | Common Use |
|---|---|---|
| White Steel (Shirogane) | High-purity carbon steel; takes the sharpest edge but is less durable. | Highest end Yanagiba and Deba knives |
| Blue Steel (Aogane) | Treated with tungsten and chromium for better wear resistance; slightly more durable than white steel. | Professional chef-grade knives |
| Stainless Steel (e.g., 440C, AUS-10) | Corrosion-resistant and easier to maintain; somewhat softer than carbon steel. | Chefs looking for low-maintenance blades |
Edge Geometry
One of the most defining features of Japanese knives is their edge geometry. Most have 15–18 degree angles, compared to 20–25 degrees for Western knives. This sharper angle allows for finer, cleaner cuts but also makes them more prone to chipping or rolling if used improperly.
Japanese professional knives are often single-beveled, especially in traditional settings. This provides unmatched precision but requires special cutting techniques. Entry-level or Western-style Japanese knives are usually double-beveled to accommodate international users.
Blade Construction
Many Japanese knife blades are constructed using a laminated technique, where a hard inner steel is sandwiched between two layers of softer steel. This gives the knife both sharpness and resilience. This method, called Sanmai, helps mitigate the brittleness of high-carbon steel while allowing for the razor-sharp edge synonymous with Japanese knives.
Handles
Traditional Japanese knives often feature wooden handles with a bolster and tang appropriate to the blade material. There are two major handle styles:
- Tall handle (Octagonal) – Made from wood with a composite of different materials, such as ebony and buffalo horn. It offers comfortable grip and aesthetic appeal.
- D-shaped handle – Designed to sit comfortably in the hand, favoring right-handed users (though newer models are made to be ambidextrous).
What to Look for When Buying a Japanese Knife
Whether you’re a professional chef or a home cook, selecting the right Japanese knife is a blend of personal preference, intended use, and budget. Here’s a breakdown of the most important considerations:
1. Blade Material
Choose based on your experience and willingness to maintain the knife. Carbon steel offers the best edge but requires regular attention and cleaning to prevent rust and staining. Stainless steel is more forgiving and ideal for everyday use.
2. Edge Bevel
Single-beveled knives are ideal for traditional chefs who specialize in tasks like sashimi cutting. Double-beveled knives are more versatile and easier to learn with, especially for Western users.
3. Type of Knife
Consider what kind of food you prepare most often. If it’s mostly vegetables, an usuba or nakiri might be preferable. If you work with fish, a deba or yanagiba is essential.

What is a Japanese knife called?
A Japanese knife is generally referred to by specific names based on its type and function, though collectively they are often called “Japanese kitchen knives” or simply “Japanese blades.” These knives have roots in Japanese culinary traditions and are known for their precision, craftsmanship, and use of high-quality materials. Unlike Western knives, which have broader, more varied applications, Japanese knives are typically more specialized and often named according to the task they are designed to perform, such as filleting, slicing, or chopping.
Some of the most common Japanese knife names include “gyutako,” “santoku,” “nakiri,” and “boning.” Each name reflects the knife’s origin, design, and intended use. Many of these names are derived from Japanese words that describe the knife’s function or cultural background. Understanding the correct terminology helps culinary enthusiasts and professionals select the right tool for their specific needs, enhancing both efficiency and enjoyment in the kitchen.
What is a gyutako knife and how is it used?
A gyutako knife is one of the most popular types of Japanese chef’s knives. The name “gyutako” literally translates to “cow slicer,” indicating its primary function as a versatile knife for cutting meat. It closely resembles the Western chef’s knife but often features a thinner blade and a sharper edge due to the higher-quality steel used in its construction. The design allows for precise slicing, dicing, and chopping, making it a go-to knife for many professional chefs and home cooks.
The gyutako knife is ideal for a wide range of cutting tasks, from slicing beef and poultry to chopping vegetables and herbs. Its balanced weight and curved blade allow for rocking motion cuts, similar to a Western chef’s blade. However, because it is typically made from harder steel, it requires more careful handling and maintenance to preserve its sharpness and prevent chipping. This knife is especially favored in Japanese cuisine for its fine edge and elegant design.
What makes Japanese knives different from Western-style knives?
Japanese knives differ from Western-style knives in several key ways, including materials, design, and intended usage. One of the primary differences lies in the blade material—Japanese knives are often made from harder high-carbon steel, which allows for a sharper and more durable edge. In contrast, Western knives typically use softer stainless steel, which makes them more resistant to rust but less sharp. Japanese knives are also generally lighter, thinner, and more precise, allowing for greater control during delicate cutting tasks.
Design differences also reflect the way these knives are used in the kitchen. Japanese knives are often crafted with a single bevel grind, which provides a sharper edge but requires more skill to use and maintain. Western knives, on the other hand, usually have a double bevel, making them more forgiving for beginners. Additionally, Japanese knife handles tend to be wooden and ergonomically shaped to fit the hand, reflecting traditional craftsmanship. These differences contribute to a unique cutting experience that is highly valued by chefs around the world.
What is a nakiri knife and what is it used for?
A nakiri knife is a Japanese vegetable knife that is commonly used for chopping, slicing, and dicing vegetables with precision. It features a straight blade edge and a rectangular shape, which allows for clean, even cuts without the curvature seen in other knives. This makes it especially effective for push-cutting through vegetables without twisting or crushing them. Its design is ideal for the meticulous preparations often required in Japanese cuisine, where presentation and uniformity are crucial.
Compared to other Japanese knives, the nakiri has a symmetrical double bevel, making it more accessible to both left- and right-handed users. It is similar to the Western chef’s knife in its ease of use but excels specifically in vegetable work due to its flat edge and thin blade. While it is not suited for cutting through tough meats or bones, it shines in tasks like julienning carrots, chopping greens, or slicing onions. For chefs and home cooks who focus heavily on plant-based dishes, the nakiri knife is an excellent, specialized tool.
What does “santoku” mean in the context of Japanese knives?
The term “santoku” translates to “three virtues” or “three virtues of the knife,” typically referring to its ability to chop, slice, and mince effectively. Santoku knives are among the most versatile Japanese knives and have gained widespread popularity both in Japan and internationally. They are often considered the Japanese alternative to the Western chef’s knife and are generally smaller in size, making them easier to handle for a wide range of cutting tasks. The blade is flat at the heel and curves slightly toward the tip, allowing for a rocking motion similar to that used with chef’s knives.
Santoku knives typically have thinner blades and a more precise edge than their Western counterparts, allowing for cleaner cuts through vegetables, fish, and thinly boned meat. They often feature a hollow edge (called “granton”) along the blade, which helps reduce friction and air pockets to prevent sticking when slicing. This design makes them especially user-friendly and well-suited for both beginners and experienced cooks who want a balanced, lightweight knife for everyday use in the kitchen.
What is the difference between single-bevel and double-bevel Japanese knives?
Single-bevel Japanese knives have only one side sharpened, which results in a sharper edge and better cutting precision. This type of blade design is commonly found in traditional Japanese knives such as the yanagiba, used for slicing raw fish, or the usuba, used for vegetable work. These knives are generally favored by professional chefs due to their razor-sharp cutting performance, but they require more skill to use and maintain. Single-bevel knives must be used with the correct hand orientation—right or left-handed types may differ—since reversing the bevel can damage the cutting edge.
Double-bevel Japanese knives are sharpened on both sides, making them more versatile and easier to use for everyday cooks. These knives are more symmetrical, allowing for balanced use with either hand, and are often more durable than single-bevel blades. Many modern Japanese knives, such as the santoku and nakiri, use double bevels for broader accessibility and ease of sharpening. While they may not attain the same level of sharpness as single-bevel knives, they are more forgiving for those learning how to use Japanese blades effectively.
What is a petty knife and how is it used in a Japanese kitchen?
A petty knife, known in Japan as a “petto,” is a small, versatile knife typically used for minor cutting tasks in the kitchen. Often considered the Japanese equivalent of a paring knife, it usually ranges between 12 to 18 centimeters in length, making it ideal for peeling, trimming, and detailed work such as deveining shrimp or slicing small fruits and vegetables. Its compact size allows for greater precision, and it is frequently used as a utility knife when a larger chef’s knife would be impractical.
While the petty knife may not be the most prominent blade in a Japanese kitchen, it plays a crucial supporting role in food preparation. It’s especially useful for tasks that require intricate, fine cutting or for working in tight spaces where a larger knife would hinder maneuverability. Many chefs appreciate the comfort of a well-balanced petty knife for delicate garnishing, herb chopping, or preparing sushi toppings. Its design aligns with the Japanese philosophy of having the right knife for each specific task, even the smallest ones.
