Shapton Glass Stone HR grain 320 coarse 45.94 micron sharpening stone, 50301

This Shapton Glass stone grain 320 is a coarse sharpening stone that will help you restore the edge of blunt knives. Great if you have owned your knife for a couple of years but have never sharpened it before. 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.
