It is great for flattening other types of sharpening stones such as Japanese Water Stones or India Oilstones.
  • Extra-Coarse (X) Black - 60 microns 220 Grit. The Extra-Coarse is used when significant removal of material is needed for damaged tools. It is also great for flattening Water Stones.
  • Coarse (C) Blue - / 45 microns / 325 Grit. The Course is used to quickly restore a cutting edge on a neglected tool or blade. It is also great for flattening Water Stones.
  • Fine (F) Red - 25 microns / 600 grit. The Fine stone will put a keen edge on a regularly maintained tool.
  • Extra-Fine (E) Green – 9 microns / 1200 grit. The Extra-Fine stone is great for polishing and refining a cutting edge after sharpening has been done of a coarser stone.
  • Extra-Extra Fine (EE) Tan – 3 microns / 8000 grit. The Extra-Extra Fine stone provides the finest polished edge of all of the bonded diamond abrasives. This stone is used to create a mirror finish to a cutting edge after sharpening has been done of a coarser stone.

Simply the Best

DMT is the leading manufacturer of superior quality Monocrystaline diamond sharpening equipment throughout the world. Renowned by professionals for the quality of diamonds used in all of their products, DMT is simply the only real choice a professional should make.

Monocrystaline Vs. Polycrystalline Diamonds

The industrial grade diamonds used in all DMT products are diamonds that are known as ‘Monocrystaline’ diamonds, because this type of diamond has a single crystalline structure. Monocrystaline diamonds are manufactured without flaws or defects, into a single uniformed cohesive diamond, which will not shatter upon use. DMT Monocrystaline diamonds are simply the best diamonds for the job; they remain whole and stable throughout their entire working life, and should therefore last even the most demanding professional many, many years of trusted and reliable service.

A word of Caution! Low quality Polycrystalline diamonds are used in cheaper versions of diamond stones. These Polycrystalline diamonds are inherently flawed, causing them to quickly fragment and shatter upon use, this fragmentation effectively, changes the nature of the diamond stones grit size value, reducing the overall grinding speed and efficiency. What is worse than this is that with little continued use these cheap Polycrystalline diamonds continue to shatter until they have simply disintegrated away to nothing. In the world of diamond sharpening, you really do only get what you pay for. Polycrystalline diamonds are simply not fit for the job ... so, when only the very best will do, opt for DMT Monocrystaline Sharpening Equipment.
