I am a newbie rockhound looking for a bevel setter in ohio that I can use on SR to set the bevel with. First question is are their any rocks around the Columbus ohio area that I can use for this purpose? We have a lot of granite. If I find some flat rocks how do I go about preparing them to hone a razor? I have heard you can use a belt sander to smooth them out with, and then do you polish them or what. I surely don't want to ruin a good razor. Third question is, I thought about getting a 10 inch tile saw to cut the rock with, thanks for any feedback.
