DMT D8XX 8-Inch Dia-Sharp Sharpening Stone, Extra-Extra Coarse, 120 Grit

Extra-Extra Coarse diamond (120 micron / 120 mesh) for extreme removal of material and edge repair. This is roughly equivalent to a 120 grit traditional waterstone, so yes, it is very very coarse!

Guaranteed not to hollow or groove, DMT®’s precisely engineered Dia-Sharp® Bench Stone with continuous diamond surface assures consistent, even sharpening every time. This D8XX extra-extra coarse plate is heavy and very flat and is very popular for flattening sharpening stones. It will also cut a new edge or tip on a damaged knife very quickly. As with all such stones, don't overdo it and let the diamonds do the work! Do just the minimal amount of strokes necessary to accomplish the task then move on to more fine grits.

Note: Even though this is popular for flattening waterstones, DMT does NOT recommend this stone for lapping/flattening waterstone and can't guarantee how long it will last under such use. Get one of the big DiaFlat lapping plates (extra-coarse or coarse) for that job, they will hold up MUCH better!

Extra Coarse diamond (120 micron / 120 mesh) for VERY fast removal of material and edge repair! 

Measures 8" x 3".

NOTE: The surface of these stones may appear scratched and there may be small indents/pits in the surface, but it's just a by-product of their manufacturing and does not affect performance.
