Thread: What is a PHIG?

In fact if I turn the Shapon over to the other side that has a blue/ green glass that you can read 0.92 through the Arkies are finer than that glass. Which was confusing to me because if this shapton is 16k I would have guess the two Arkies to be 50k easy.

It really just does not work that way. You cannot identify the grit equivalence of a hone by touch. I have tried out many hones that FEEL glassy smooth yet still will chew up an edge.

Also this. You can't feel differences on this fine a scale. The particulate matter is literally too small beyond probably 8k.

I understand you can't do it that way I'm not expert on figuring out the grit size. I use my finger and my tongue (after washing the stone) That is why I asked. I can't really blame the Chinese guys for guessing at the grit.
