Shapton Glass Stone HR Grit 500 Coarse 29.4 Micron Sharpening Stone, 50102

This Shapton Glass Stone grain 600 is a sharpening stone that will help you sharpen knives that have lost their sharpness. Grain 600 is coarse enough to quickly remove material and restore the edge of a blunt knife, but not coarse enough to restore a damaged edge. For it you need a coarser sharpening stone. The sharpening stone sharpens quickly and evenly. Which is exactly what we’re looking for from a high-quality sharpening stone. Contrary to what you might expect from the name, the glass doesn’t do the sharpening. You sharpen on a high-quality Japanese whetstone. A layer of tempered glass is attached to this to prevent bending.
