Debado is a premium series from Suehiro made of aluminum oxide with the magnesia binder similar to Chosera and Shapton Pro series. The magnesia binder gives Debado excellent sharpening quality and performance, and high wear resistance. Debado series stones are universal and can be used to sharpen knives of any steel including high carbon, vanadium, and chromium steels.
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.
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.
