As far as the OP first knife material, I think it is steel from a file. Not positive. The edge is acceptable for my purposes. Here's another one I bought from Bryan Crow in Oregon. It's too big for use but I really liked it. I don't know if he still does them. I have a certificate around here somewhere for it. It has a 14" blade.
