The DMT DuoSharp Bench stone is a two grit sharpening stone designed to stand up to the tough task of sharpening ceramic knives. The same tough qualities that make ceramic an ideal material for durable edges, make it a difficult edge to sharpen. DMT's exclusive HardCoat technology creates a more durable bond between the diamod abrasive and the steel substrate preventing the abrasive from breaking free and falling away.
The technology used on the hardcoat DuoSharp stones is the same used on the DiaFlat flattening plates, which were created to resist the abrasion of flattening water stones. If you own ceramic knives, and have been looking for a solution for keeping them sharp - look no further. That said, this is a specialty stone, and if you primarily sharpen steel tools - even exotic alloys or carbide - we recommend you go with a standard Duosharp or DiaSharp stone as the added cost is of limited benefit.
The Fine/Extra Fine grit stone will put a sharp edge back on kitchen knives, and comes with a DuoBase for stable, skid-free sharpening. The diamond surface measures 8 1/16" by 2 5/8"
