Venev Centaur³ Series Dual Side Resin CBN 6" x 1"

Venev Centaur³ Series Dual Side Resin CBN are used for sharpening knives on Hapstone, TSProf, and all Edge Pro compatible guided sharpening systems, as well as freehand sharpening. CBN (Cubic Boron Nitride) is the second-hardest material after diamond. CBN sharpening stones offer excellent performance in sharpening knives of any steel.

Centaur³ Series is dual side sharpening stone with two 1mm-thick CBN-bearing layers on the aluminum plate. CBN layers contain evenly distributed CBN grains with resin bonding. Bonded CBN provide excellent feedback and give the sharpening stone a much longer lifespan.

OCB is a proprietary binder with no abrasive particles in the composition. OCB is available in fine grits only and offers better scratch-free sharpening results.

All Venev diamonds use FEPA-F grit classification. Centaur³ Series is available in six grit combinations. F80 to F240 utilize legacy binder, F400 to F2000 utilize OCB binder. Centaur³ series is available only in 100% CBN concentration.

Resin Binders

B1-10 - Boron-modified phenolic resin (BPF) composite - Made of powdered bakelite, copper additive

B2-01 - Boron-modified phenolic resin (BPF) composite - Made of liquid bakelite, iron additive (softer than В1-10)

В2-01М - Boron-modified phenolic resin (BPF) composite - Made of liquid bakelite, copper additive (softer than В2-01)

OSB (OCB) – A proprietary phenolic resin composite.

(OSB and OCB refer to the same binder; the difference arises from a transliteration quirk of the Cyrillic “ОСБ,” which can be rendered as either “OSB” or “OCB” in Latin script.)

Understanding Dimensions (GOST notation) Dual-sided stones have 5 numbers: length × width × full thickness × thickness of abrasive layers for both sides If abrasive layer thickness is variable, the minimum thickness is noted.
Single-sided stones with backing have 4 numbers. Monolayer stones have 3 numbers. Curved stones have a radius of curvature inmm: R40
