Identifying grits

samedi 16 mai 2015

Got a couple of diamond stones, one started as Coarse and while it still cuts I think it's lost some of its sharpness, the Fine stone seems to have retained most of its sharpness. Is there any way of finding out roughly what their grits are?
I'm getting a burr of the Fine stone that seems to take forever to remove manually, fortunately I can power strop it away but it would be nice to do it manually, maybe I need an Extra Fine Diamond stone?
