Venev Orion Series Diamond 100%

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

Orion series consists of a 3 mm-thick diamond-bearing plate on an  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 8 grits from F 60 to F 2000. F60 to F 240 utilize legacy binder with 100% diamond concentration. F 400 to F 2000 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.

FAQ

• Do I need to lap Orion diamonds?

  Lapping improves the sharpening quality of fine OCB diamonds, but it's not mandatory. Lapping can also eliminate the break-in period after purchase. Lapping is strongly recommended for OCB 2000.

• Which type of diamond is better bonded or coated?

  Coated diamonds have all the diamond grains on the surface, maximizing performance. Bonded diamonds spread the diamond grains over their whole volume, and work in similar fashion to conventional abrasives. Only bonded diamonds can be flattened, lapped, repaired or refreshed. Bonded diamonds are universal and able to sharpen any steel. Bonded diamonds have much better feedback and a longer lifespan.

• Can I buy Venev diamonds to sharpen all my knives? If they are okay for hard steel, they should be even better for soft steel, right?

  Yes, Venev diamonds are universal and will wear extremely slowly on both hard and soft steel.

• Can I sharpen ceramic knives with Venev diamonds?

  Theoretically, yes. However, sharpening ceramic knives is technically difficult and uneconomical in most cases. Diamond stones can cause microchipping when used on ceramics. Consider purchasing a new ceramic knife instead of sharpening it.

• Well-known manufacturers like DMT and Eze-Lap use coated diamonds in their products. Doesn't that mean bonded diamonds are inferior?

  Absolutely not. Coated diamond technology is developed in the USA due to its lower cost. The bonded diamond technology is more advanced and more expensive.
