I'm working on tracking down domestic equivalents to Japanese Sword Polishing Stones. I'm having excellent results with a few of my "finds" and moderate results with others.
For example, sawn Picture Jasper (diamond bladed saw) makes a nice razor stone, but isn't very aggressive. The same goes for Pennsylvania Bluestone.
What I want to get a hold of, and hope that someone here might help with, is silica shale. If anyone has a suggestion or a source, I'd love to hear about it.
Thanks!
