Japanese knives and sharpening, explained with the numbers.

Start here

Four ways in, depending on whether you want to buy a knife, learn to sharpen, settle a comparison, or understand the steel.

• 

  Chef Knives

  Gyutos, Western chef's knives, santokus and sets — compared on the numbers that actually decide a cut: steel grade, HRC hardness, blade length and geometry.

• 

  Whetstones & Sharpening

  Whetstones, grit progressions and technique — the reproducible way to put a scary-sharp edge on any knife, plus the stones worth buying.

• 

  Knife Comparisons

  Head-to-heads for the decisions people actually get stuck on — chef's knife versus santoku, gyuto versus a Western chef's knife.

• 

  Guides & Learn

  The reference layer every roundup cites: how to buy a Japanese knife, and the steel-and-hardness guide behind our whole method.

Because we don’t pretend otherwise. Everyone in this category says they tested twenty knives in a lab; most can’t prove it. We haven’t, and we say so. Here is what we do instead — and it’s checkable.
