  • Hone Your Knowledge of Japanese Cooking Knives

Japanese kitchen knives are known for their superb quality and aesthetic appeal around the world. The issue is that they are surrounded by so much legend and romanticism, not to mention a mind-bogglingly vast variety of prices and varieties, that it can be challenging to choose.

These chef’s blades are dependable, accurate and of course sharp enough to make them the tool of choice in many professional kitchens across the world. But what distinguishes a sushi knife from a general-purpose kitchen knife? And why not fillet a fish with a veggie knife? Find out by reading on.

Japanese vs. Western knives

Modern Japanese knives are known for being expertly polished and constructed from durable high-quality steel.

Hagane, a kind of carbon steel with several gradations, is typically used to make Japanese knives. Hagane is a metal that can be used to create cutting tools because it can maintain an incredibly sharp edge. However, since hagane is relatively soft steel, it must be maintained often. While expert chefs consistently sharpen and care for their knives, a hagane blade that is not maintained will become dull, chip and rusty.

As a result, the edges can retain their sharpness longer. Compared to Western knives, the blade can tolerate more wear and tear, although the tougher steel can be brittle. You must be sure to use the appropriate Japanese knife for each operation. The edge of the Japanese chef’s knife may be damaged if you attempt to cut through a chicken bone with it, as opposed to the Western chef’s knife. The blade shape of Japanese-style knives is also distinct in that it is rarely ever curved. Due to their length and straightness, long and straight-edged knives should only be sharpened with special care.

In your quest, you can also come across a lot of ways, or conventional Japanese wooden handles. When selecting a knife, the grip is crucial since it affects the tool’s balance and weight. Additionally, the handle changes how the blade is used by making it lighter and more front-loaded.

Stainless steel or high carbon?

Stainless steel is an alloy of iron, approximately 10-15% chromium, possibly nickel, and molybdenum, with only a small amount of carbon. Kitchen knives with excellent stainless steel blades are rust resistant, simple to maintain, sharp, retain their edges, and simple to resharpen. As a result, they are becoming well-liked by both novice and intermediate users.

High-carbon steel is a higher-grade stainless steel alloy containing a certain quantity of carbon. It is designed to combine the greatest qualities of carbon steel with regular stainless steel. High carbon stainless steel blades keep their edge for a significant amount of time without fading or staining.

General rules for choosing a knife shape

  • A knife made for cutting fresh fish has a very thin blade, but a knife used for cutting vegetables and fruits has a considerably wider blade;
  • The more curved the edge, the better suited it is for chopping, rolling, cutting and slicing. The simpler it is to slice (with a lateral motion, as you would with smoked salmon), dice (as you would do with potatoes or vegetables), and chop (with a straight vertical cut), the smoother the edge will be;
  • For cutting quickly or with a conventional rolling action, narrow blades are not appropriate. Furthermore, they cannot be chopped with them;
  • Since wide blades are typically longer than their smaller siblings, paring, peeling, and general cutting with them in hand is challenging.

Design

Unsurprisingly, the fundamental structure of a knife (a blade with a handle) has essentially not altered much over the past 10,000 years. The materials used to make knives and the forms of their handles, however, have changed and continue to change. Generally speaking, the following factors affect the knife’s cost and quality:

  • the grade of the steel or other material used to make the blade;
  • the knife’s weight and feel;
  • how the blade was shaped;
  • the ability to avoid corrosion, the edge’s durability, and its sharpness;
  • re-sharpening frequency;
  • handle design, forging, and quality.
