Micron sized monocrystalline diamonds are securely bonded in nickel that is electroplated to precision ground steel. An injection molded polycarbonate base increases the structural rigidity needed to maintain a flat sharpening surface.

The innovative pattern of the recessed dots is key to the DMT difference. By providing a space into which metal fines produced from sharpening can be cleared, the dots keep the diamond surface clean for fast and efficient hone of all materials.

Ideal for knife and general tool sharpening.
