Venev Bonded Diamonds are used for sharpening knives on Hapstone and Edge Pro knife sharpeners. Diamond sharpening stones offer excellent performance in sharpening knives of any steel.

Venev Diamonds consist of a 3 mm-thick diamond-bearing plate on an Edge Pro aluminum base. The diamond-bearing plate contains evenly distributed diamond grains with resin bonding. The manufacture of bonded diamonds is more complex than for coated diamonds. Bonded diamonds provide better feedback and give the sharpening stone a much longer lifespan.

The OCB version of Venev Diamonds utilizes a brand-new yellow binder with no abrasive particles in the composition. OCB is available in fine grits only and offers better scratch-free sharpening results.

All Venev diamonds use FEPA-F grit classification. Orion series is available in 7 grits from F 60 to F 1200. F60 to F 240 utilize legacy binder with 100% diamond concentration. F 400 to F 1200 utilize OCB binder with 25% or 100% diamond concentration. 25% diamond concentration is better for scratch-free sharpening. 100% diamond concentration is better for high performance.

How to use

Venev 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 an acceptable practice, although it results in faster wearing and speeds up stone loading.
