How to use bundled stones


Bundled stones are made of aluminum oxide. Water is required to use. Immerse all stones in water for 10 minutes before use and keep them wet during the work. Do not keep the stones in water for long time.

Stone set is optimized for sharpening knives made of soft steels. Using the stones with steels with hardness more than 59 hRC is not recommended.


Bundled diamonds are dual-sided, one side is coarsier than other. Three stones have total six grits. It is little bit tricky to identify grits. You can find identification marks on side face. The mark is grit specified in FEPA-F scale with arrow symbol facing to corresponding surface. A finer side is always copper colored.

All diamonds are bonded, not coated. It means you can clean, refresh, flatten and lap your diamond like any other synthetic stone. It's recommended to use water as lubricant to prevent stone loading.


  • What Limited Edition means?

    Hapstone V6 Deluxe Limited Edition is produced in very small and fixed production run. Only 23 pcs have been made. All Deluxe sharpeners are blue.
