How to use

Hapstone CBN Plates are recommended to be used with water as a lubricant for the best feedback, but can also be used dry. Clean or rinse after use, and store in a dry place in between use to prevent any oxidation on the metal matrix.

CBN Plates are ferromagnetic and should not be used on magnet-based knife sharpeners.
