DMT® Difference

Sharpening with diamonds results in the finest, sharpest edges and Diamond Machining Technology (DMT) products are the finest Diamond Sharpening products available – Worldwide. What does the "DMT® Difference" mean? Simply put, DMT® has done only one thing since 1976 – innovate and build the world’s best diamond sharpeners. Whether in continuous diamond surface or our trademark interrupted "polka-dot" pattern – don’t accept imitations.

Highest Product Quality in the Industry

Diamond Quality – DMT uses only micronized monocrystalline diamonds produced using a proprietary process that ensures very consistent grit size. Users can rely on our sharpeners to provide exactly the finish they want – no scratches where they don’t belong.

Diamond Coverage – DMT’s sharpeners have the most diamond per square inch in the industry. This means your DMT® sharpener will give you the highest level of performance for many years.

Flatness – Employing know-how developed over our 35 years of continuous improvement DMT ensures that your sharpener is the flattest available and will never hollow or groove. Flatness is critical so that your woodworking tools can provide the precision results for which they were designed.

Innovation – DMT invented the interrupted "polka-dot" sharpening surface in 1976 and has remained the innovation leader ever since. From the best-selling Diafold® line through the high-tech DuoSharp® line and onto the recently patented Magna-Guide™, DMT has led the way in bringing new ideas to sharpening. The company's products have been recognized with awards for design from the International Spark Design Awards, for innovation at the International Practical World Exhibition held in Germany and The HANDY Magazine Innovation Awards, as well as seven "Blade Magazine" Knife Accessory of the Year awards. DMT has also been the recipient of a Silver Award in the Merchandising category by the North American Retail Hardware Association (NRHA)
