How was the DMT sharpener invented? Originally a manufacturer of grinding wheels, the company repurposed a center punch-out of a diamond grinding wheel and developed an entire new way of manual sharpening. Suddenly, there was an available alternative to the traditional methods of sharpening that required no messy oil, never grooved or hollowed, and lasted and lasted. It was an unbreakable, clean-cutting, and super-fast sharpener. It is a tool that could sharpen any material, including the toughest composites, ceramics and any metal, including tungsten carbide and even polycrystalline diamond inserts.

For long-lasting performance, DMT makes certain that each sharpening surface carries the most diamonds per square inch in the industry. 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. DMT sharpeners are engineered to be the flattest on the market, and built to outlast other products, which are variable in surface, and often warped, hollowed or grooved.

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. Proving more than just the best way to produce a first-rate edge, their sharpeners save you from coping with an entire toolbox of second-rate ones. That’s why you owe it to yourself, and your tools, to choose nothing less than a DMT diamond sharpener. Take a look at their full line of products and place your order today.
