Venev Orion Series Set "Sirius" includes six 6" resin-bonded diamond stones: F80, F150, F240, F400, F800, and F1200.

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.
