How to care for a Japanese knife

Four thirty-second habits so the edge lasts for years and the pattern keeps its shine.

Wash it by hand and dry it right away

This is the rule that changes everything. Damascus steel is stainless, not indestructible: prolonged moisture and harsh dishwasher detergents dull the pattern and can pit the edge. Warm water, a drop of soap, a soft sponge, and dry it with a cloth straight away. Thirty seconds.

Never in the dishwasher

Not even “just once”. Heat warps the resin and wood handle, the salt in the detergent attacks the steel and knocking against other cutlery chips the edge. It’s the number one reason warranty claims get rejected across Japanese cutlery.

Cut on wood or plastic

Glass, marble or ceramic boards destroy any edge within weeks. An end-grain wooden board or a polyethylene board yields to the edge instead of crushing it. And use the right motion: push and slide, don’t crush. For bones, frozen food or very hard squash, use another knife.

Keep it in its sheath

Every Kaen comes with a sheath. Use it: a drawer without a sheath means an edge knocking into everything else. If you prefer a magnetic strip, place the spine first and then the blade, never the edge.

Once a month: a few strokes on the honing rod

A honing rod doesn’t sharpen, it realigns. Ten gentle strokes at about 15° bring the edge back to “like new” between real sharpenings. When the rod is no longer enough (every few months, depending on use), it’s time for the stone: we explain how in the sharpening guide.
