DMT

Diamond abrasives provide the fastest, easiest and most effective way to sharpen an edge. Unrivaled in both performance and durability, DMT® brand sharpeners have earned the reputation as the best sharpening products on the planet.

The DMT® Difference

Since 1976, DMT® has been in business to do just one thing: make the world’s best diamond sharpeners. Product innovations such as our signature polka-dot interrupted surface, and others with our continuous surface of high-performance diamond, are praised worldwide for their superior quality. From pocket-sized whetstones to heavy-duty bench stones, the difference arrives time and again through our undivided pursuit of sharpening excellence.

Quality Must Be Manufactured, Not Fabricated

Diamond Coverage differs widely from one manufacturer to the next. For long-lasting performance, DMT® makes certain that each sharpening surface carries the most diamonds per square inch in the industry.

Diamond Uniformity is also key to sharpener performance. DMT® uses a proprietary process that ensures near-perfect consistency in grit size. The result is a micronized monocrystalline diamond that covers evenly across the sharpening surface to prove effective with every use, year after year.

Beware of Imitators!
