Description

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 organic 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 extra-fine grits only and offers better scratch-free sharpening result. Venev OCB Diamonds are available in F 800 and F 1200 grit only.

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.

All Venev diamonds are recommended to be lapped. Additional flattening and lapping can be performed by a customer to improve sharpening quality. We recommend using loose silicon carbide powder. Using diamond lapping plate are not recommended.

We strongly recommend lapping the ultra-fine version (F 1200 and F 2000 grit) after purchase.

FAQ

  • I have the original Venev diamond stone 1200 grit. Do I need the OCB?

    Legacy binder composition includes medium-hard particles up to 7 microns large. (It was necessary to stabilize diamond/binder matrix.) As result, when sharpening some steels the legacy F 1200 and F 2000 may not show noticeable progression after F 800. In this case, the new OCB diamonds will be the good upgrade.

  • Do I need to lap OCB diamonds?

    We recommend lapping all Venev diamonds including OCB because flatness tolerance is the same as for legacy diamonds. However, it's not mandatory for OCB version because the surface is finer.

  • 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.

  • Venev 2000 grit diamond creates very large grooves on the cutting edge. What is wrong with it?

    This is completely normal for diamond sharpening, especially on high carbon steels. Diamonds offer high performance, sacrificing cutting edge quality. If you need a very accurate cutting edge, you should switch to non-diamond abrasives.
