What to know before you buy
About this knife
- Deba knives of this 165mm length are a mid size that suits smaller boards and kitchens.
- It has a Japanese-style (wa) handle: a handle without a metal bolster, set into the blade with a hidden tang.
- Shirogami (White steel) is a carbon steel that rusts and stains if it is left wet, so it is wiped dry after every use.
Limits to know
- It is single-bevel: sharpened on one side only, made for one hand, and harder to sharpen well than a double-bevel knife.
- Carbon steel develops a patina and can rust; it is not for a knife that sits wet in the sink.

Good to know for beginners
A deba is the thick, single-bevel fish knife for breaking down whole fish, heads and small bones. Shirogami (White steel) is carbon steel: very sharp and easy to sharpen, but wipe it dry while you cook or it will rust. The Japanese wa handle is light and puts the balance toward the blade.
