DMT® Diamond Whetstones™ are renown for their remarkable sharpening speed. The sharpening speed of DMT® products is a function

of the quality of the micronized super abrasive, monocrystalline Diamond.

MONOCRYSTALLINE Diamond

(a strong, single crystal)

Uniform and precisely sized Monocrystalline Diamond is permanently bonded to nickel on a precision ground plate. Approximately two

thirds of each crystal is embedded in the nickel with one third exposed. Because Diamonds are the hardest material known, the working

abrasive points (top third of the diamond) will wear very slowly to give a long product life. Extremely pure, DMT® diamond crystals permit a

single layer of diamond to perform for years. Competitors claims of multiple layers of diamond only indicate poor quality diamond that

quickly wears.
