What about pipe stone? Sounds awfully similar to these scotch
stones. I've got some but nothing at the moment to test it on.
I can scratch the surface with fingernail, very easy to carve as

and at one of the quarries only hand tools are allowed, you must
have permit and I think have tribal affiliation. Anybody know if
they're similar? Curiously, Kat
