The DMT Difference

Diamond Uniformity, Coverage, Surface Flatness

Uniformity: DMT is the only manufacturer of diamond sharpeners that uses micronized monocrystalline diamonds, precisely sized for a more uniform diamond surface.

Coverage: DMT’s process assures the most diamonds per square inch in the industry providing a more durable sharpening surface.

Surface Flatness: DMT bench stones are engineered precision flat, assuring even contact with the knife or tool during the sharpening process.

Choice of Diamond Surfaces

Interrupted or polka dot surface for which DMT is famous has slightly recessed holes that will collect metal fines (swarf) removed during sharpening to prevent loading. Fast sharpening action; not recommended for pointed or very small tools.

Continuous surface presents a more conventional looking sharpening surface. Fast sharpening action; able to use on small surface edges.

HardCoat, DMT’s newest proprietary surface, is able to withstand the rigors of ceramic sharpening, providing an even longer service life to the sharpener.

DMT Commitment

DMT is committed to providing the best diamond sharpeners in the marketplace. If the sharpener is found to be defective, it will be replaced.
