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 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.
Venev OCB Diamonds are available in F 1200 grit (2.5 um) only. F 800 grit (6 um) will be released soon.
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 a diamond lapping plate are not recommended.
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.
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.
It will not be released due to substantial technology limits. F 2000 will be legacy only.
