Answer Question
Patchy grit on the 60
I recently received my 120 and 60 grit metallic cbn stones. The 120 grit feels fairly consistent across the surface like a Venev resin bonded 100, but the 60 grit metallic cbn has some fairly sizable patches that feel smooth to the touch and these spots feel a little lower than the gritty parts of the surface. Can I flatten\prep these stones before use with a course water stone or is buying lapping supplies also required? The description says Poltava metallic cbn stones don't require preparations but I think one of mine slipped through QC.
