Thanked: 458Right, thus the comment "if they are that nicely shaped". It's easier to talk about the size of the particles if the discussion is simplified. The surfaces of most hard stones look like stacked dandruff under a microscope.
a quality Jnat will be hard enough to not release slurry on its own. Releasing slurry is not good because it will mix with the worked slurry and mess up the refinement of the bevel. To overcome the hardness fo the stone one uses a softer slurry stone.
But since we're trying to grade a finish stone based on what it's capable of, it's not really based on particle size within a relative range. Thus, my only real question is how hard is it bound together, how fast does it break in and will it still polish the work done by a slurry once it's broken in. Some super super hard stones still have to be conditioned a little bit from time to time as they are even slow to polish.
