What Japanese homes actually do

Our editor’s routine

Knife enthusiasts often warn that a pull-through sharpener wears a blade faster than a stone and leaves a rougher edge. That is true. For a stainless santoku that cuts dinner every day, it is a trade many Japanese cooks accept without a second thought.

When a whetstone is worth it

A stone earns its place when the knife needs it: carbon steel, single-bevel knives, or big jobs where the edge has to be perfect.

If that sounds like you, read carbon or stainless. If it doesn’t, start with a stainless santoku and a simple sharpener.

Questions people ask

Will a pull-through sharpener ruin a Japanese knife?

It removes more metal than a stone and gives a rougher edge. For a stainless santoku used at home, our editor finds a simple sharpener is enough. For a carbon or single-bevel knife, use a stone or a sharpening service.

How often should I sharpen?

When it stops cutting cleanly through a tomato skin. Our editor's rule of thumb: daily use makes a santoku dull, so keep a simple sharpener within reach.

Where can I get a knife sharpened?

In Japan, butchers and fishmongers will sometimes do it. Elsewhere, look for a local knife shop or sharpening service.
