DMT Diamond Machining Technology will celebrate its official 35th anniversary on August 31. To commemorate this milestone, DMT is producing a tri-color (red, white and blue) limited edition set of Diamond Whetstones that will be available only from August to October 2011.

The 35th Anniversary Diamond Whetstone Set comes in a hardwood box with rubber feet and includes three 6-inch Diamond Whetstones color-coded according to grit: red – fine grit (25 micron / 600 mesh), white – medium grit (35 micron / 450 mesh), blue – coarse grit (45 micron / 325 mesh). This marks the first and only time that DMT had created a Medium grit stone.

DMT’s 6-inch Diamond Whetstones feature an interrupted diamond surface in the company’s signature polka-dot pattern. The surface is layered in precisely micronized monocrystalline diamond embedded in nickel, a DMT proprietary process. The polka dots allow metal fines to fall into recesses.

DMT’s Diamond Whetstones offer a wide sharpening surface to accommodate the variety of edges found on all kinds of knives and tools. Applications span the culinary, gardening, woodworking and outdoor recreation markets.   Unlike conventional stones, there are no messy oils to struggle with. A few light strokes with the manual sharpener are all that’s needed.
