A moravia frictionite and an olean frictionite 00. All 4 sides were at least as out as the coarse of this olean... Well out... Another observation, they're hard and all, but if this is the baseline hard, there is a bit of hype about lapping these/the brutality. It may be I was broken by the apache black gila and various arks over the years, but this is nothing... Tiny little compact circles and the thing rains material. Long linear for bulk removal on these seems to be a mistake, it fights a lot more. Both are in good nick, but the olean is definitely harder. It also has a slightly different odor when lapping to the newer one. Definitely lap and recondition though. I was expecting them to be out but it surprised me how concave they all were.
