Hapstone Premium Diamond is a new series of diamond stones for sharpening knives using guided knife sharpeners (Hapstone, TSPROF, and other Edge Pro-compatible sharpening systems). Hapstone Premium Diamond utilizes advanced hybrid metal-organic binder - composite of traditional copper-tin alloy and polymer components. Hybrid binder inherits exceptional wear resistance and cutting performance of metallic binder.
Hapstone Premium Diamond consists of a 3mm thick diamond-bearing metal plate mounted on a premium black aluminum blank.
Diamond offers excellent performance in sharpening knives of any steel.

Attention! Hapstone Premium Diamond stones may seem bald out-of-the-box. This is normal.
Hapstone Premium Diamonds are recommended to be used with water as a lubricant for the best feedback. The diamond does not absorb water. Splash water on the stone's surface. Dry usage is acceptable practice.
Premium Diamond stones do not require any preparations.
