DMT Diamond Whetstones are a dependable maintenance free sharpening system with a classic look. Each stone comes in a wooden box, and is color-coded by grit size. The interrupted diamond surface quickly sharpens wide tools, because the dot wells capture the dust created by sharpening, leaving the abrasive clear of debris.
Diamond abrasive works dry or with a splash of water. Clean up is generally non-existent, but in the event you do want to clean the stone, just erase the surface with a polymer eraser, or rinse it off in the sink.
DMT bench stones use a generous and even distribution of monocrystaline micronized diamond abrasive bonded to a nickel plated steel surface. DMT's proprietary diamond coating method creates a stone that is both durable and precise. The resin body of the Diamond whetstone is engineered for flatness, and has two tabs at the ends with holes for permanently mounting the stone.
The interrupted surface of the stone works very well on wide tools, but can catch gouges, and tools with a narrow point of contact with the stone. We recommend DMT's polka-dot sharpening products for tools 1/4" or wider. Depending on your technique and the specific tool being sharpened you may be able to go smaller than that without trouble.
Always store stones dry, a simple wipe with a towel is enough. At first the diamond surface will feel very aggressive. After the first few sharpenings the stone will develop a smoother feel without losing performance.
Dimensions: The 8 1/8" by 2 5/8" abrasive surface. Overall dimensions of the stone are 9 1/8" by 2 1/8" by 1 1/8" overal dimensions of the wooden box are 10 1/4" by 3 5/8" by 1 5/8"
