Care Instruction
- Don't cut hard things! Japanese knives are brittle so bone hacking is a NO NO!
- Wash with neutral detergent after use, and wipe dry;
- Please don't wash knife with dishwasher, it will damage the wood handle;
- Be careful not to leave the knife close to a heat source for a long time;
- It is a lot more dangerous to cut with a blunt knife than a sharp knife!
- It is best to sharpen a Japanese knife regularly on a waterstone.
- Oil the (carbon) knife if storing for an extended period of time to prevent rust.
