Defining Japanese knives

Comparing to Western-style knives, Japanese knives have single beveled blades. This means Western-style knives are sharpened on both sides of the blade, while Japanese style knives are only sharpened on one side. Another characteristic of Japanese-style knives is ultra-sharp blades that not only cut better but also remain sharp for a longer time before needing to be sharpened again. This is explained by the type of steel used for the production of the knives. It often has a high carbon content that allows them to be harder and more rigid. Japanese knives’ blades are thinner, sharper, and much lighter than their Western counterparts. The lightweight and sharpness make the knife easier to handle and lends itself well to Japanese cooking which typically requires more detail and precision.

Types of Japanese knives

Even though they share common features, Japanese knives come in various types to fit different tasks. Single-edged knives are usually specialized for one purpose. The examples of these types are ‘deba’-used for fish butchery and ‘usuba’ -used for vegetable-cutting. There are also multipurpose styles, such as the ‘gyutou’ –  the most common and used type of Japanese knife used for almost all cutting tasks including vegetables, meat, fish and ‘santoku’ – another all-purpose Japanese knife found in most Japanese homes used for slicing, dicing and mincing.

The beauty of Japanese knives

Japanese knives stand out for having aesthetic blades and beautiful, D-shaped handles, and are mostly even packed and soled in elegant boxes with Japanese characters that add to the overall experience of entering the Japanese cutlery world. Besides that, there are some types, called Damascus knives that have blades made of several layers of steel. The steel layers are usually visible on the blade’s surface as they form original wavy patterns. Another known aesthetic feature found in some of the Japanese blades is the ‘tsuchime’- finish that consists of hammering the blade to create an irregular surface. Other than given them an amazing look hammered finish also helps to reduce the blade’s stickiness.

In Japanese cuisine, the appearance and presentation of the food are getting quite a lot of attention. Therefore different cutting techniques are depending on what you are cutting, and what knife you are using. While some techniques are basic, others require a great deal of skill, training, and experience. Some vegetable cutting techniques include rangiri ( meaning ‘random cuts’), Icho-Giri (quarter rounds), and Katsuramuki (rotary sheet cutting). Rangiri is a technique used to cut vegetables like carrots and cucumbers into uneven shapes of the same size.  “Icho” means ginkgo in Japanese, so vegetables cut in Icho-Giri style result in a quarter-circle shape that looks like a ginkgo leaf while Katsuramuki is the cutting method to turn a cylindrical vegetable into a thin, flat sheet.
