Experience the DMT Difference! DMT's uniquely designed diamond sharpening stones will hone even the hardest material with much less time and effort required by conventional stones. Interrupted pattern increases cutting action while clearing fines from the diamond surface. The Diamond Whetstone will remain flat, requires only water as a lubricant and is virtually indestructible.
DMT History
August 2007 marked DMT’s 31st year as the leading innovator of manual diamond sharpening technology for people and industries dependent upon high performance edges. Incorporating diamond’s ability to abrade hard metals, DMT’s engineering and product development expertise and patented processes have evolved and expanded to service industrial, commercial and consumer markets. The company offers sharpening solutions for virtually every user—from do-it-yourselfers to large commercial operations. DMT’s specialized, precision sharpening systems function easily and efficiently to sharpen, hone, lap or deburr in the production, maintenance and repair cycles of a myriad of products.
The entire line of DMT products is manufactured in the company’s facility in Marlborough, Massachusetts. Home to the firm since 1983, the facility accommodated sales, marketing and production departments. The expanded production area houses first-of-its-kind injection molding systems complete with robotics to produce its patented DuoSharp® lines as well as the internationally recognized polka-dot patterned Diamond Whetstone™ line. DMT products have always been made in Massachusetts.
The company’s story began in Hudson, Massachusetts on the third floor of an old mill where DMT first developed and produced diamond saw blades for use in cutting blocks of granite. With a 1978 change in U.S. foreign policy, America released a significant part of the stockpile of industrial diamonds to Israel, causing world prices to plummet and DMT sales to plunge to near zero. Faced with the need to diversify, the company made a rather unlikely discovery.
From a round, four-inch, discarded center punch-out of a diamond grinding wheel grew the potential of a new tool. This diamond-surfaced plastic, perforated punch-out was transformed from waste material to sharpening innovation. It was an unbreakable, clean-cutting, super-fast sharpener, requiring no oil as lubricant. It was a tool that could sharpen any material, including the toughest composites, any metal, including tungsten carbide and even polycrystalline diamond (PCD) inserts with mechanical assistance – in other words, by hand.
After receiving and testing a sample sent to them, a purchasing agent for L.L. Bean extolled the product’s sharpening performance and suggested DMT consider a non-circular shape. By reshaping to a rectangular stone and the additional development of manufacturing and plating technologies to serve the sharpening needs of many diverse markets, DMT was on its way to becoming the recognized leader and the industry standard in diamond honing hand tools. L.L. Bean remains a DMT customer to this day.
DMT’s unprecedented engineering abilities provide customers with sharpening tools for processes requiring extraordinarily precise tolerances. To insure flat and stable sharpening surfaces, the company has invented a unique mold design that allows the mating of perforated steel inserts to engineered grade resins. DMT diamond surface flatness exceeds that of ground steel plates—a precision standard not attained by other manufacturers or sharpeners.
A variety of successful new products in receptive markets fueled DMT’s growth. Many innovative firsts, now copied but never equaled, are:
The Crystal Saver® — Rescues fine crystal, restoring serviceability and beauty by smoothing rough and chipped edges.
The DuoSharp® — Multi-patented, first two-sided bench stone, manufactured using the latest technologies to ensure unparalleled precision flatness.
The Diamond Whetstone™ — Renowned polka dot pattern diamond surface that facilitates quick, precision honing of all tools in every market.
The The Diafold® Serrated Knife Sharpener — Sharpens the range of serrated blades in both outdoor and culinary markets.
The Double Sided Diafold® Diamond Sharpener — First two grit sharpening in a convenient pocket sized tool.
6-in-1 Unbreakable Diamond-Ceramic Triangle Sharpener — Combines a patented process which transforms the surface of aluminum to an extremely hard, dense aluminum oxide with DMT diamond strips to create a multipurpose 6 in 1 triangular sharpening tool.
Diafold® Magna-Guide™ Sharpening System — A Diafold® fine / extra-fine sharpener and Aligner™Blade Guide joined with a Magnetic Angle Guide (MAG) offers portable, adjustable guided sharpening. The blade guide provides 7-Angle adjustability for the right edge every time.
The ever evolving DMT line now numbers some 300 different products, targeting markets as varied as culinary, lawn and garden, woodworking and carving, outdoor, speed skate/ski/snowboard, camping, fishing, hunting, police/security, military, industrial, commercial and home improvement (DIY). Entering international markets in the 80’s, the progressive company introduced multi-lingual packaging and marketing materials to present and promote their brand globally. DMT continues to experience growth internationally and exports to 40 countries throughout the world. The firm has been acknowledged with seven Blade Magazine Knife Accessory of the Year Awards and has also received an international award for innovation at Germany’s Practical World Exhibition.
