Venev Dragon Series Dual Side Diamonds are used for freehand sharpening knives. Diamond sharpening stones offer excellent performance in sharpening knives of any steel.
Dragon Series is premium level dual side diamonds with 2 mm-thick diamond-bearing layers glued to the aluminum plate. The diamond layer thickness is twice more than in the Phoenix series and has tighter flatness tolerance. The diamond-bearing layers contain evenly distributed diamond grains with resin bonding. Bonded diamonds 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. Dragon Series is available in six grit combinations.
F80 to F 400 utilize legacy binder. F 400 to F 2000 utilize OCB binder. All combinations are available in 100% diamond concentration only.
Attention! OCB 2000 is an experimental product of Venev in all form-factors.
OCB 1200 is an optimal finish stone for most because it creates a beautiful mirror finish edge and a very good scratch pattern.
OCB 2000 creates hair whittling edge of good geometry and improves edge retention. However, OCB 2000 creates a scratch pattern with parasite scratches caused by diamond agglomeration.
Finish with OCB 1200 if the aesthetic is your priority, or you are in doubt.
Finish with OCB 2000 if the functionality is your priority.
Additional lapping is strongly recommended for OCB 2000 to improve the sharpening result. Use loose silicon carbide powder of progression F120 -> F400 -> F2000.

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.
