The KME Gold Series diamond-coated sharpening stone extra, extra coarse, 100 grit is a very coarse sharpening stone you can use to reprofile and fix damaged knives and axes. Do the edge of your knife or axe contain any dents or marks? With this sharpening stone you can fix all of that. We do, however, recommend finishing the edge with a slightly finer sharpening stone. This sharpening stone is meant for the KME Precision Knife Sharpening System, Diamond Stone Kit, the KME Precision Knife Sharpening System, R.P.S.H. Combo Kit or the KME Axe Sharpener Kit.
This diamond-coated sharpening stone is comprised of a metal sheet that contains small synthetic diamonds. Diamond is very hard which means that diamond-coated sharpening stones quickly remove material. Don't apply too much pressure! The diamonds are placed in a layer of nickel. If you sharpen too hard you push the diamonds out of the sharpening stone.
