High-performance ceramic sharpening stones with a hybrid bond for controlled sharpening and refined finishes across a wide range of knife steels.
Abrasive
Ceramic abrasive provides clean and controlled cutting while working delicately with the steel matrix and carbide structure.
Bond
KDTU’s multi-component hybrid bond based on modified resins combines high wear resistance with stable and predictable sharpening performance.
Steel range
Suitable for carbon, stainless, tool, high-speed, and powder metallurgy steels across a wide hardness range.
Performance
Hybrid Ceramica works more delicately with the steel matrix and carbide structure than aggressive diamond abrasives, producing a clean and refined surface.
On softer steels, the cutting speed can be comparable to or even faster than diamond stones. On high-hardness steels, the stone maintains effective cutting action while providing excellent control and surface quality.
Maintenance
The surface releases metal contamination easily and can often be refreshed with a small amount of Hapstone Magic Oil and a quick wipe.
Lubrication
Hybrid Ceramica can be used dry, with water, or with oil. Hapstone Magic Oil or a suitable sharpening emulsion is recommended for a cleaner sharpening surface and easier maintenance.
Quality
KDTU sharpening stones are manufactured under documented quality standards.
