Yes, I lapped both of them on sandpaper, using a piece of thick plate glass that I keep for that purpose.

I've had a chance to play with them a bit more. I now believe the 3-line Swaty is actually COARSER than my cushioned strop hone (!) It is also very fast-cutting and has a much higher coefficient of friction than any of my other hones. I think the 2-line Swaty sits somewhere between the C.S. hone and the Gem hone. I think the Swaty-3 will be useful for completely resetting the bevel on edges that I've convexed into oblivion with the Cr02.

I think Randy is on the money here: barber hones have a lot of variance in grit size from batch to batch.

BTW, both hones say "AUSTRIA" on them, if that matters.
