Hi Double Axe. Ceramic stones are made differently than normal stones, so there is no "grit" size to speak of the . The alumina particles are 15 to 25 microns, but the "grit" is created in firing and grinding processes. That's why we call it an "Ultra fine"

I think what double axe meant was how does it compare to other types of benchstones.
Off the top of my head, these criteria are:
How fast it "cuts".
How fine a finish does it leave?
