Got this stone today, tagged as a TOS.
I did some looking thru the net, and seen there were different looking , and grades of this stone.
I can tell you this much, its grayish blue, with light gray specks, and harder than $#!+ to lapp. I've gone thru 3 sheets of 220 wet n dry, and probably 2 more to get it done.
So I'm curious, does anybody know what this might be, or is it a TOS.
