Exactly what I was thinking. My intention is to use them for the very hard natural stones like Arkansas, Charnley Forest, CH12k, TOS, etc. and using it to do the bulk of the coarse work.

I was also considering converting one plate to a lapping plate, with cross diagonal grooves. I will see how it works without the grooves first.

BTW, the reason I purchased 3 was that they were all in one auction lot.
