TOJIRO’s July 2019 reference separates edge direction from handle shape. The distinction helps explain handedness beyond a knife-type name.
Technique and structure
TOJIRO distinguishes single bevels formed from one side from double bevels formed from both. It describes double bevels as generally usable with either hand; single bevels require attention to handedness. Oval nakiri handles and ridged deba or yanagiba handles illustrate a second question: handle orientation. Check both details on the actual model.
Check the actual model
Some gyuto are single-bevel, TOJIRO notes. The name alone does not establish a model’s handedness or availability.
For international readers
Ask for the exact bevel specification and handle configuration before ordering. A general explanation of manufacturing possibilities is not a quotation of today’s price, lead time or overseas service.

包丁の利き手：刃付けと柄の形を別に確認する
藤次郎の刃向きの解説は、片側から刃を付ける片刃と両側からの両刃を区別します。両刃は基本的に左右を問わず使える一方、片刃では利き手の確認が重要です。出刃や柳刃などのしのぎ付きの柄にも左右性が関わります。牛刀にも片刃の例があるため、形の名前や「和包丁」だけで判断せず、個別製品の刃付けと柄を確認します。
