Difference between Japanese and Western knives

Whether you prepare Japanese food or not, a well-made knife may greatly improve your cutting abilities and the quality of your meal. Finding the knife that matches you, though, might seem like a difficult endeavor given the variety of brands and price points available. Let’s examine the little-known benefits and mysteries of utilizing Japanese kitchen knives in more detail.

Japanese and Western knives


Hagane (鋼), a form of carbon steel that is typically used to make Japanese knives. The blades are forged in stages, starting with a hard carbon steel core and ending with a softer iron steel coating. This combination results in a very sharp Japanese-style sword-like edge. Hagane is less durable than stainless steel and is susceptible to chipping from hard fish bones and rusting from leftover food particles or water droplets on the blade. Therefore, to prevent rust and dulling, expert cooks maintain their knives meticulously.


Japanese kitchen knives have the sharpest blades in the entire globe. When a soft sponge is used to wash a well-honed Japanese kitchen knife, the sponge may be sliced through with just a light touch of the blade. Japanese kitchen knives are that sharp. Regular maintenance is crucial because the longer you use the knife, the more rapidly the blade will start to wear down and get dull. If you treat your knives well, they will undoubtedly become some of the most cherished kitchen accessories that you will cherish for a very long time.


Traditional Japanese knives have a single-bevel blade with a sharpened edge on one side and a fully straight side on the blade surface. This edge makes it suitable for precise slicing movements. You just sharpen one side of the blade when you sharpen it. However, since single-beveled blades are designed for right-handed users only, left-handed people have to use specialized left-handed knives, which can be costly.

Western knives, in contrast, have two bevels. The edge of double-beveled blades is typically V-shaped. Although not intended for extremely precise cuts, it is considerably simpler to sharpen.

The taste of the food

In many cultures, cutting food involves pulling the knife away from your body. The situation is the exact reverse in Japan. Food is frequently sliced by pulling the knife in your direction. When you cut food this way and with the grain, it will have a smooth texture, however, when you cut food against the grain, the flavor will be diminished. The sharpness of a knife may drastically alter the flavor depending on how it is handled, which is a very intriguing observation.

The appearance of the food

As was already said, one of the qualities of a sharp knife is its ability to cut food with grain without significantly altering the flavor, which also results in a very attractive cross-sectional look. For instance, every Japanese meal offered at upscale Japanese restaurants looks beautiful. One of the reasons for this is that the chefs employed by these upscale restaurants utilize sharp, high-quality blades to create a smooth, pleasing cross-section of the meal. In this way, Japanese cuisine is aesthetically beautiful as well to the palate.

Japanese and Western kitchen knives are both composed of stainless steel, which is a lot more robust and easy to keep. They are appropriate for people who like to avoid the routine maintenance of a Hagane knife and are resistant to rust and corrosion. Keep in mind that stainless steel knives have advantages over Hagane, such as maintaining their sharp edge and being simpler to sharpen.

The various kinds of Japanese cooking knives

1. Nakiri bocho (菜切り包丁)

Nakiri bocho

Vegetable peeling, chopping, and slicing. The blade is double-beveled, straight, and thin. Knives from Kanto are rectangular, whereas those from Kansai have rounded tips. Its blade measures 240-300 mm in length. It costs less and is less difficult to sharpen than a Usuba.

2. Usuba bocho (薄刃包丁)

Usuba bocho

Usuba bocho is Nakiri-like but with only one bevel. The Nakiri’s blade edge is substantially thicker, making it ideal for cutting ornamental shapes and paper-thin slices. Chefs favor the Usuba over the Nakiri because of its accuracy, although it might be difficult for beginners to sharpen the blade.

3. Deba bocho (出刃包丁)

Deba bocho

It is used for breaking down, descaling, and gutting fish. To handle cutting heavy fish bones, it features a thicker blade. For various fish sizes, it is available in 3 sizes. Kodeba (子出刃) has a blade length between 90 and 120 mm, Hondeba (本出刃) is a normal size of around 210 mm, and Miokoshi Deba (身卸し出刃包丁) is between 180 and 270 mm.

Santoku bocho

Its name, which translates to “three virtues,” refers to the fact that it works well with meat, fish, and vegetables. This multipurpose knife was developed during the Meiji period, a time when Western food became increasingly popular among Japanese consumers and the lines between Western and Japanese cuisine began to blur. They work well for extended cutting strokes and chopping. Most Japanese households now just use one Santoku knife instead of the Deba and Usuba.

How to choose a proper Japanese knife?

It may be useful to think about the following issues when you browse knives at a store:

  • Grip: How does holding it feel in your hands? Is it big enough for your hands to get lost in, or is it so thin or thick that your fingers bump into one another awkwardly when you grab the handle?
  • Weight: Is the blade too hefty or too light for you? Will your hands and arms become fatigued from carrying the knife for a period of 10 to 15 minutes? Or do you like a knife that is a little heavier?
  • Length: Is the blade too long or too short? Knives with smaller blades, for example, should be used by those with smaller hands.
  • Material: Do you favor blades made of stainless steel or Hagane? As was already noted, stainless steel maintains its sharpness and is less work to maintain than Hagane.
  • Craftsmanship: Do you trust workmanship in general? While most knives created in Japan are hand-forged, more affordable blades are mass-produced in China.

Overall: Do you like the way the knife is made and how it looks? Would you want a blade engraving? Even if appearances alone won’t improve your knife abilities, you should choose the one you enjoy!


Can I use a Japanese knife for Western-style cooking?

Japanese knives are a great addition to any kitchen. Their accuracy and sharpness allow them to be used in a variety of cuisines, from Japanese to Western and fusion cuisine.

Are Japanese knives suitable for beginners?

Yes, Japanese knives can be suitable for beginners, especially those who are willing to invest time in learning proper knife techniques and maintenance. Starting with a versatile and forgiving knife, such as a Santoku, can be a good entry point.

How often should I sharpen my Japanese knife?

The amount of time you need to sharpen your knife varies depending on how often you sharpen it, but in general, you should sharpen your knife regularly. You can also sharpen your knife with the whetstone if you notice that your knife isn’t sharp enough or that you’re having trouble making clean cuts.

Can I use Japanese knives for cutting through bones or frozen food?

Japanese knives, particularly gyuto and santoku, aren’t designed to cut through bone. Doing so damages the blade or chokes it. For such jobs, use a specialized knife such as a cleaver.

How should I care for my Japanese knives to maintain their quality?

  • Keep your knives clean and dry by hand so they don’t corrode.
  • Sharpen your knives with high-quality whetstones and honing rods.
  • Store your knives in the knife block or a magnetic strip to prevent damage.
  • Don’t put your knives in the washing machine as the high temperature and abrasive cleaning agents can damage the blade.

What should I look for in the blade material of a Japanese knife?

Choose high-carbon stainless or Damascus steel knives. These materials provide superior sharpness, excellent edge retention, and corrosion resistance, so your knife will last longer.

What is the difference between a Gyuto and a Santoku knife?

Both are multi-purpose knives, but Gyuto has a longer and sharper blade, making it easier to rock and slice. On the other hand, Santoku has a shorter and wider blade, making it easy to chop and slice with a gentle rocking motion.
