Naniwa Snow White

Single #8000 finishing stone

A single #8000 finishing stone with no maker particle size. The value here is a JIS #8000 inference, not a measurement. Faded.

Each grade below shows its size in microns, its spread (the published distribution, where a maker or standard gives one; most makers publish none), and where that size lands on the reference scale, a shared yardstick for reading grit numbers across makers.
