Cubic boron nitride works efficiently while leaving a cleaner scratch pattern than sharper, more aggressive abrasive structures. Bonding Durable, softer feel The metal-organic bond is close to metal bonds in wear resistance, while giving the stone a softer and more comfortable sharpening feel. Maintenance No coolant required Hapstone Premium CBN stones do not require soaking, special preparation, or cutting fluids before sharpening. Control Stable angle between grits Stones of different grit sizes share the same dimensions, allowing you to move from one sharpening stage to another without changing the sharpening angle. Each stone is mounted on anodized aircraft-grade aluminum blank for stable support during work. For the best sharpening experience, recommends using Hapstone Magic Oil.

For finishing, Hapstone Poly Diamond suspension is recommended.
