DMT Knife Sharpener, Diafold

DMT Knife Sharpeners are diamond coated sharpeners with a distinctive hole break up pattern. The innovative pattern of recessed holes provides spaces into which metal filings may be cleared from the sharpening surface. It is a DMT innovation and trademark. DMT also uses single head Monocrystalline diamonds, which are more expensive than multi-head polycrystalline diamonds. These Monocrystalline diamonds are securely bonded in nickel, and then are electroplated onto the perforated stainless steel plate; all of which is supported by a lightweight fiberglass reinforced polycarbonate base. (DMT also offers inexpensive solid stainless steel plate knife sharpeners, without the hole break up pattern.)

Unlike a conventional knife sharpener, a DMT Sharpener stays perfectly flat for precise sharpening, won't develop grooves or hollows, and never needs dressing. They work perfectly well dry, but water may be used as a lubricant. Oil is not recommended.

A diamond knife sharpener is almost a requirement to cut and finish today's high-tech, high-chrome blade steels that can easily reach 60-62 Rockwell. If you have had a hard time sharpening stainless steel, and are currently using Arkansas or similar stones, switching to a diamond knife sharpener may solve your problem. Knives Plus â has sold DMT knife sharpeners for 20 years, and can whole heartedly recommend them to all of our customers.

Color of the DMT knife sharpener designates diamond grit: Green indicates Extra Fine; 9 micron 1200 mesh, Red indicates Fine; 25 micron 600 mesh, Blue indicates Coarse; 45 micron 325 mesh, Black indicates Extra Coarse; 60 micron 220 mesh.

Applications for DMT knife sharpeners:

1. Use Extra Fine grit (Green) for final polishing of a knife edge after being sharpened on coarser stones. (Knives Plus â recommends this stone for final razor edge polishing on CPM440V and S30V stainless steels.)

2. Use Fine grit (Red) to hone a knife edge that has been regularly maintained.

3. Use Coarse grit (Blue) for cutting tools, or to restore a knife edge on a dull blade. (We at Knives Plus â do not consider this stone a coarse stone. Knives Plus â designates this stone as a medium grit: use it for general field touch-up and sharpening.)

4. Use Extra Coarse grit (Black) for garden tools, axes, chisels, or lawnmower blades, or for rapid stock removal on damaged knife blades.

5. DMT sharpeners (1-3) can also be used to sharpen carbide router bits, saw blades, chisel edges, and to touch up chips in fine crystal glassware.
