Venev Centaur Series Dual Side Diamonds are used for sharpening knives on Hapstone and TSProf guided knife sharpeners, as well as freehand sharpening. Diamond sharpening stones offer excellent performance in sharpening knives of any steel.
Centaur Series is dual side diamond with two 1 mm-thick diamond-bearing layers on the aluminum plate. 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. Centaur Series is available in six grit combinations.
F80 to F 240 utilize legacy binder. F 400 to F 1200 utilize OCB binder.

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.
Venev Diamonds may have the flatness tolerance up to 0.2 mm. Additional flattening and lapping can be performed by a customer to improve sharpening quality. We recommend using loose silicon carbide powder. Using a diamond lapping plate is not recommended.
