Sneak Peek: Venev OCB Bonded Diamonds

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 1200 grit (2.5 um) only. F 800 grit (6 um) will be released in Q1. Dual-sided formats of OCB will be released at the same time.

  • 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.

  • How about OCB F 2000 grit?

    It will not be released due to substantial technology limits. F 2000 will be legacy only.

As the owner of Gritomatic online store I'd like to use this blog to talk with you and share my knowledge and experience in sharpening. English is not my native language, I am sorry for any mistakes and really hope it will not become a barrier between us. I will be happy to receive feedback from your side.
