Japanese Knife Picker

Not sure whether you want a gyuto, santoku, nakiri or petty, or what length? Answer three questions and this picks a starting point.

How this works

Lengths are the edge length most makers list. Most home cooks find a 210 mm gyuto the easiest all-rounder. A 240 mm blade is faster on large prep but needs more board and more confidence. The board size uses a simple rule: blade length plus about 4 inches.

Rules of thumb, not guarantees. Check the maker's own specs and care instructions for your knife or board. Last reviewed October 28, 2026 by The End Grain Cutting Board Guide team.
