The Complete Guide to Japanese Style Kitchen Knives

Japanese kitchen knives are a symbol of Japan’s culinary heritage. They are a testament to the skill and dedication of the craftsmen who create them.

Japanese kitchen knives, from the renowned Santoku to the specialized Yanagiba, are more than just tools. They are a testament to centuries-old traditions of Japanese blade-making, a craft perfected in the samurai era and carried forward to today’s culinary world. Each knife is a work of art, crafted with meticulous attention to detail in cities like Seki, known as the ‘City of Blades’.

The scarcity of these knives is not due to a lack of materials or technology, but a deliberate choice. Each knife is carefully crafted, requiring the skills of a master craftsman. The result is a tool of unparalleled quality and performance, as seen in the hands of sushi masters and Michelin-starred chefs.

In this article, we will explore the world of Japanese kitchen knives. We will delve into their history, craftsmanship, and what sets them apart from other knives. We will take you into the workshops of the master craftsmen who create these knives, and into the kitchens where they are used daily.

What are Japanese knives?

Japanese kitchen knives, known as “Hocho,” are globally renowned for their craftsmanship, sharpness, and precision. Each knife is a product of Japan’s rich cultural heritage and culinary tradition.

Several types of Japanese kitchen knives exist, each designed for specific tasks. Deba knives are used for filleting fish, Usuba knives for precision cutting of vegetables, Santoku knives are versatile all-rounders, and Gyuto knives, similar to Western chef’s knives, are used for a variety of tasks.

Japanese kitchen knives are made from high-carbon steel, which provides a sharper and more durable edge. The blade is often layered with softer steel to create a balance of sharpness, durability, and flexibility. This process results in a blade with superior slicing precision.

The handles of these knives are typically made of wood, designed for comfort, balance, and optimal control. They are usually asymmetrically shaped, catering mostly to right-handed users, but left-handed versions are also available.

Creating a Japanese kitchen knife is a traditional process passed down through generations, emphasizing detail, balance, and respect for the food.

Using a Japanese kitchen knife goes beyond its functionality. It’s about experiencing a piece of Japanese tradition and improving the quality of your cooking. With a Japanese knife in your kitchen, you’re investing in a timeless culinary tool that embodies a blend of tradition and innovation.

Main features of Japanese kitchen knives

Japanese kitchen knives are known for their top-notch quality and unique designs, all thanks to Japan’s rich history and blade-making skills. These knives stand out because of three main things: how sharp their edges are, their shape (also known as ‘bevel’), and the type of metal used to make them. In this section, we will be taking a closer look at these features. We’ll talk about what makes the edges so sharp, compare two different shapes (single and double bevel), and explore a special kind of metal called ‘Tamahagane’ used in some of the best Japanese knives.

Knife’s edge

The edge of a Japanese knife is one of its most distinctive and important features. Japanese knife edges are thinner than those found on their Western counterparts. This isn’t just a minor detail – it plays a critical role in how the knife performs.

The thin edge makes Japanese knives exceptionally sharp. Because of the reduced thickness, these knives can slice through ingredients with less resistance, allowing for precise, clean cuts. It also enables the knife to cut without crushing, maintaining the integrity of delicate ingredients.

This thinness, however, also means that the edge of a Japanese knife can be somewhat delicate. While they’re excellent for precision slicing, they may not be suitable for heavier tasks like deboning meat or cutting through hard vegetables. Japanese knives are designed with specific tasks in mind, and using them appropriately can greatly extend their lifespan.

Single bevel vs. double bevel

Single bevel knives are traditional in Japanese cuisine. They have one side ground to form an edge, while the other side remains flat. This asymmetric design allows for extremely sharp edges and offers excellent precision. Single bevel knives are ideal for specific tasks such as creating thin sashimi slices or intricate vegetable cuts.

On the other hand, double bevel knives are sharpened on both sides, forming a symmetrical edge. This design, while not capable of the same level of precision as a single bevel, is more forgiving and versatile, making it ideal for a variety of general culinary tasks.

Which one is better?

For precision tasks like slicing sashimi or decorative vegetable cuts, single bevel knives like yanagiba or usuba are superior. However, for versatility across various tasks, such as slicing, dicing, or mincing, double bevel knives like gyuto or santoku are more suitable and easier to handle for those not trained in traditional Japanese knife techniques.

Blade’s steel

The type of steel used to make a knife blade significantly affects its performance and maintenance needs. Japanese knife-makers have a rich palette of steels to choose from, each with its own set of characteristics.

High-carbon steel is a common choice for Japanese knives due to its hardness. Hardness in knife steel is critical because it determines how sharp the knife can be and how long it will hold its edge. High-carbon steel can be honed to a very sharp edge and generally holds this edge well, which makes it ideal for tasks that require precision.

However, high-carbon steel is also more susceptible to rust and corrosion than stainless steel. It requires more meticulous care, including prompt cleaning and drying after use, to prevent rusting.

Stainless steel, on the other hand, is more resistant to rust and corrosion, making it a practical choice for many chefs. It doesn’t require as much maintenance as high-carbon steel and can handle more exposure to moisture. However, while stainless steel knives can be very sharp, they often can’t reach the same level of sharpness as high-carbon steel knives, and they may not hold their edge as long.

Japanese blades can also be made of laminated steel, where a harder type of steel is sandwiched between two layers of softer steel. This combines the benefits of hardness (from the hard steel) and durability (from the softer steel).

Tamahagane

Tamahagane, meaning “jewel steel,” is a type of steel traditionally used in crafting high-quality Japanese knives and swords. This steel is produced using a unique, labor-intensive method called Tatara, where iron sand and charcoal are heated in a clay furnace. The resulting steel has distinct layers of varying carbon content, which are carefully selected, combined, and forged to achieve an optimal balance of hardness and flexibility.

Tamahagane steel knives are known for their excellent edge retention and ability to be sharpened to a very fine edge. Due to their high quality and the intricate process required to produce them, they are typically more expensive and considered a premium option among Japanese knives.

Different types of Japanese kitchen knives

Common types

Common types of Japanese knives are versatile and used for a wide range of tasks. Examples include the Santoku, the Gyuto, the Bunka, and the Kiritsuke, designed for everyday cooking needs.

Santoku

The Santoku knife, directly translating to “three virtues,” is a versatile kitchen tool perfect for slicing, dicing, and chopping. Characterized by its relatively short, broad blade, typically ranging from 5 to 7 inches in length, it’s designed with a “sheep’s foot” blade shape for a more linear cutting edge.

Santoku knives are traditionally made from high-carbon steel or stainless steel and feature a double bevel edge, which means they’re sharpened on both sides. Generally lightweight and well-balanced, they provide easy maneuvering during food preparation. Santoku knives come in a wide price range, from about $20 for entry-level models to $200+ for high-end versions. A suitable alternative to the Santoku would be the Western-style chef’s knife.

Balance is centered for all-around utility. Nakiri knives range in price from $40 to $200+. A good alternative to the Nakiri is the Usuba or a Western-style vegetable knife.

How to choose a Japanese kitchen knife?

Choosing the right Japanese kitchen knife involves considering several key factors. Here’s a guide to help you navigate through the process:

1. Purpose: First and foremost, understand what you need the knife for. Different Japanese knives serve different purposes. For instance, if you often cook fish, a Deba or Yanagi knife may be a good choice. If you need a versatile all-rounder, then a Santoku or Gyuto could serve well.
2. Material: Japanese knives are typically made from either high-carbon steel or stainless steel. High-carbon steel is extremely sharp and maintains its edge well, but it can rust if not cared for properly. Stainless steel is less prone to rust and easier to maintain, but it may require sharpening more often. There’s also Damascus steel, which combines the benefits of both and has a beautiful pattern but comes at a higher price point.
3. Blade Type: Japanese knives come in single-bevel (sharpened on one side) and double-bevel (sharpened on both sides) types. Single-bevel knives, typically used in professional settings, offer superior sharpness and precision but require more skill to use. Double-bevel knives are more user-friendly and versatile.
4. Size and Weight: Choose a knife that fits well in your hand and is appropriate for the tasks you’ll use it for. A lighter, shorter knife like a Santoku is easier to handle for quick, precise tasks, while a longer, heavier knife like a Gyuto may be better for more robust jobs.
5. Balance: The balance between the blade and handle affects the knife’s feel and performance. A blade-heavy knife gives more power to your cuts, while a handle-heavy knife offers better control.
6. Handle: Japanese knife handles come in a variety of materials, from traditional Ho wood to modern composites. Some people prefer the feel and grip of a certain material, so it’s best to hold a few to see what works for you.
7. Budget: Japanese knives can range in price from budget-friendly to quite expensive. Determine how much you’re willing to spend and remember that while higher-priced knives often offer better quality and longevity, there are plenty of reasonably priced options that perform excellently.
8. Maintenance: Some Japanese knives require more care than others. High-carbon steel knives, for instance, need regular oiling and proper storage. Consider how much time you’re willing to invest in maintaining your knife.

Differences between Japanese and Western knives

In the world of kitchen knives, two styles really stand out – Japanese and Western. These two styles have their roots in different cultures, and that’s reflected in how they’re designed and used. From the materials they’re made of, to how they’re shaped and sharpened, Japanese and Western knives are unique in their own ways. But what exactly sets them apart? Here, we’re going to lay out these differences in a simple table, and then we’ll talk a bit more about what each of these points mean.

Feature	Japanese Knives	Western Knives
Sharpness	Typically sharper due to a smaller edge angle.	Generally less sharp due to a larger edge angle.
Edge Shape (Bevel)	Single or double bevel, depends on the specific knife type.	Typically double bevel.
Material	Often high-carbon steel such as VG10 or white/blue steel.	Typically stainless steel or high-carbon stainless steel.
Blade Thickness	Thinner blades for precision.	Thicker blades for durability and heavier tasks.
Hardness	Softer due to less carbon content, which provides flexibility and durability.	Typically harder due to high carbon content, making them stay sharp longer.
Price	Tend to be more expensive due to specialized production methods.	Often less expensive and more readily available.
Purpose	More specialized knives for specific tasks (e.g., Sushi knife, vegetable knife).	More general-purpose knives (e.g., Chef’s knife, paring knife).
Balance	Typically balanced toward the blade for precision cutting.	Usually balanced toward the handle for a firm grip.

Firstly, the shape or bevel of a knife’s blade sets them apart. Japanese knives are generally single-bevel, meaning they are sharpened on one side, making them exceptionally sharp. Western knives, on the other hand, are typically double-bevel, sharpened on both sides and are slightly less sharp but can handle a wider range of tasks.

Secondly, the material used for the blades differs. Japanese knives often use high-quality carbon steel, sometimes with names like VG-10, AUS-8, or SG2. These materials can hold a very sharp edge but require careful maintenance to prevent rusting and chipping. Western knives commonly use stainless steel or high carbon, which might not hold as sharp an edge but are typically more durable and resistant to rust.

The weight of the knives is another factor. Japanese knives are often lightweight and balanced, which allows for precision and control. Western knives are usually heavier, which can be advantageous for heavy-duty tasks like breaking down poultry or chopping hard vegetables.

The edge angle of Japanese knives is narrower (around 15 degrees or less), providing a razor-sharp edge ideal for precise cuts. Western knives have a wider angle (20-25 degrees), which is sturdier and more robust for a variety of tasks.

Lastly, while Japanese knives are often designed for specific tasks (such as a Sashimi knife for slicing raw fish), Western knives tend to be more general-purpose tools that can be used for a range of different tasks in the kitchen.
