King (Matsunaga)

Waterstone line

King (Matsunaga) publishes no particle size. These are grit-chart estimates keyed to the printed number, not maker data. 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.
