You were right Eddie. It'll work just fine with copper. It might do better with hammerstones or antler, but I couldn't do any better with those. I did notice it seemed to work better with a heavy bopper as compared to a lighter one. You'll come across spots in the rock that I don't think it would matter what ya hit it with...it ain't moving!
I done most of the finish work on the Pickwick with antler. The beaver lake started out going to be a dalton until I checked my book and found no dalton points in that region.
