Makes no difference Tim. It's fun to work with. It carves slowly...you actually scrape to carve it rather than cut off a shaving. You'll see once you get started. I've read that Minnesota is where the sacred pipe stone was harvested. But there is a vein of it near St. Marysville in the southern part of our province. I have a pipe carved by a friend, of that stone. Other similar stone was used by our aboriginal peoples to make these pipes...Steatite, Catlinite (pipe stone named by caucasians after George Catlin), Argillite, and Soap Stone, to name those that come to mind.
