In 1976, as the U.S. celebrated its Bicentennial, a Massachusetts company began manufacturing diamond sharpeners in a facility 30 miles west of Boston. While it may not have been “the shot heard 'round the world,” DMT did indeed start its own revolution, and changed the face of sharpening forever.

Over the next four decades, the company built its reputation as the worldwide leader by innovating and producing the highest quality knife and tool sharpeners available—reliable, durable and recognizable through their iconic polka dot design.

One hundred percent of DMT’s sharpeners are Made in the USA, because quality is DMT’s most important differentiator. And, American ingenuity is just as big a part of the DMT story. The company holds more than 10 patents and has introduced more than 125 new products, including 10 in the past five years alone—a testament to the manufacturer’s tradition and spirit of innovation.

“We have thrived and grown worldwide by sticking to tried and true principles—superior product Made in the USA, backed by friendly customer service and delivered by people who care about their customers,” said Mark Brandon, President of DMT.

Today, DMT products are sold in dozens of countries from Canada to Australia. In recognition of its contributions to the expansion of U.S. exports, DMT received a 2014 President’s “E” Award for Exports and an Associated Industries of Massachusetts International Business Council (AIM-IBC) 2012 Global Trade Award.

Prized by woodworkers, gardeners, chefs and home cooks, outdoor enthusiasts, and knife collectors alike, DMT’s American-Made diamond sharpeners reflect a long-term commitment to excellence the world over.
