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. After testing a sample of a center punch out sent to them, a purchasing agent for L.L. Bean extolled the product’s sharpening performance and worked with the engineers at DMT® to refine the resulting product..The result of that cooperation launched DMT® 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.
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 was a tool that could sharpen any material, including the toughest composites, ceramics and any metal, including tungsten carbide and even polycrystalline diamond (PCD) inserts.
