Shapton Glass Stone HR 30000 nano fine 0.49 microns sharpening stone, 50403

This Shapton Glass Stone grain 30000should be a part of a completely different category. This ultra-fine sharpening stone is comprised of sharpening particles as small as half a micron! With this sharpening stone you remove all tiny scratches and irregularities. The result is an edge that is so smooth as a mirror and with which you can cut without feeling any resistance. 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.
