Venev Chameleon Series Dual-Sided Metallic-Bonded CBN are designed for use in sharpening systems such as Hapstone and TSProf. CBN (Cubic Boron Nitride) is the second-hardest material after diamond, offering exceptional wear resistance and thermal stability. CBN sharpening stones provide excellent performance when working with high-alloy, powder, and hardened steels.

The Chameleon Series is Venev’s first dual-sided stone featuring Metal Matrix Composite (MMC) binders. MMC is a new generation of metallic binders, often referred to as “hybrid.” The Chameleon Series utilizes a reinforced copper–tin bronze alloy MMC: MS1 binder for F80–F800 grits and MB1 binder for F1200.

The Chameleon stone is a 6 mm solid abrasive stone consisting of two 3 mm CBN-bearing layers fused together.

All Venev CBN stones use FEPA-F grit classification.
