Traditional Japanese knives are single or asymmetric bevel blades made for specific jobs, such as slicing raw fish, breaking down whole fish or cutting vegetables. They are thin, sharp and precise, and they do best with careful handling.
The six knives below are well known Japanese styles. Several use carbon steel, which needs wiping dry to avoid rust, and some are blades for specialists. We keep to general descriptions and leave blade length and weight for you to confirm on the listing, because each style comes in several sizes. We have not used these products ourselves, so confirm sizes, materials and what is included on the current listing before you buy.

Care and Setup
- Wipe carbon steel dry right after use to prevent rust, and apply a thin film of food-safe oil if you will not use it for a while.
- Hand wash and never use a dishwasher.
- Sharpen on a whetstone and learn the bevel angle.
- Store with a sheath or in a knife block, and keep the edge away from other metal tools.
Mistakes to Avoid
- Cutting bones with a delicate yanagi, which is made for slicing and can chip.
- Leaving carbon steel wet.
- Using a glass or granite board.
- Skipping the sharpening skill, since these knives are at their best with a regular whetstone routine.
Japanese Knife FAQ
Are Japanese knives harder to care for?
Carbon steel ones are, since they can rust, though stainless versions are easier. All of them do best with hand washing and a proper board.
Are they left or right handed?
Single bevel knives are made for one hand, so confirm before buying.
Do I need all of these?
No. A gyuto or nakiri covers most home cooking, and the specialist knives are for specific tasks. Start with the knife that matches what you cook most often.
