It all starts with a knife. A knife that deserves respect and requires proper maintenance. Keep it sharp, the magazine articles say. But this can be a difficult and frustrating process. Old crafts are becoming less important, and tool sharpening skills are no exception. Our mission is to ensure this craftsmanship endures. The idea of knife sharpening being performed by the individual to whom the knife belongs is close to our heart. As such, the support we offer our customers includes information about sharpening stones, abrasives and knife maintenance. We provide modern, high-quality sharpeners that give a fast, long-lasting edge, as well as various stones and accessories. We have a great love for the craft of knife sharpening, and our aim is to share this passion with our customers.

    Sneak Peek: Venev OCB Bonded Diamonds

    December 14, 2018

    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.
