🔹 Key Features & Benefits

CBN Abrasive — Designed for Hardened Steel

Cubic Boron Nitride is the best abrasive for modern high-hardness steels.
It cuts fast, stays sharp, and maintains geometry even under heavy load.

Hybrid Bond combines the strength of metal bonds with the smoothness of resin:

• Creates micro-serrations for aggressive slicing performance

This is the bond professional sharpeners choose for maximum sharpness and efficiency.
