About Kobocho Knives

Kobocho are short and wide knives with sharp blades ideal for intricate tasks such as deboning, filleting, and grating small fish.


The steel used is mainly Aogami #2, which has high hardness (HRC60-62), but is relatively easy to sharpen, has good tenacity (rugged), has excellent sharpness, and offers the best balance of performance.

Carbon steel is mainly Aogami (Blue) steel #2, which offers the best overall balance of performance. Specifically, Aogami (Blue) steel #2 has the following features:

  1. Contains chromium and is rust-resistant.
  2. High hardness (HRC60) and good sharpness.
  3. Tough blade and resistant to spills.
  4. Not as hard as Aogami Super (HRC64) or #1 (HRC62) steel and is relatively easy to sharpen.
Shirogami (White) steel is pure carbon steel that is reasonably priced but rusts easily. We have a variety of stainless steels such as Ginzan, VG10/5/1, AUS10/8, high-speed powdered steel (SRS, SG2), and others.
