Japanese Cutlery: A Practical Guide

A reference for people buying, using, and maintaining Japanese kitchen knives. It assumes you are past the "which brand is best" stage and want to understand what actually differs between one knife and another.

How this guide is organised

Choosing a knife covers the things that determine how a knife performs: blade shape, steel, grind, heat treatment, construction, finish, and handle. Read Grinds and Heat Treatment first if you read nothing else, because those two decide more about a knife than the steel name on the spine does.

Who makes them is organised by region, because region still predicts a great deal about how a knife is built. Sakai runs on division of labour, so a Sakai knife is usually a smith plus a sharpener plus a house, and you will find those three filed separately. Sanjo, Echizen, and Tosa workshops more often do everything under one roof, so one entry covers the knife.

Sharpening and Buying are practical. Reference holds the glossary.

What this guide is and is not

It is a compilation, written from maker sites, specialist retailers, and community sources, and checked where checking was possible. Where something is contested, it says so. Where a claim rests on a single retailer page or a forum post, it says that too. A guide that hedges in the right places is more useful than one that sounds certain about everything.

It is not a review site, it does not rank makers, and it takes no position on which knife you should buy. It is free, non-commercial, and carries no affiliate links.

A note on names

Japanese maker names are romanised inconsistently across the English-language market, and the same person routinely appears under two or three spellings. Where sources disagree, the alternatives are noted in the entry. Several makers are also regularly confused with each other; those cases are flagged where they occur.
