The entire line of DMT products is manufactured in the company's facility in Marlborough, Massachusetts. Home to the company since 1983, the facility accommodates DMT's 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® line as well as the internationally recognized polka dot patterned Diamond Whetstone line.
   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.
