KME Gold Series diamond sharpening stone coarse, grain size 300

The KME Gold Series diamond-coated sharpening stone coarse, 300 grit is a coarse sharpening stone meant to sharpen really blunt knives and axes. Is your knife or axe blunt? With this sharpening stone you can easily sharpen the edge of your axe or knife. We do, however, recommend using a finer sharpening stone afterwards to finish the sharpening process. 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.
