Hi, new here and a rank ametuer. I have made scant few knives but do have a little backyard savvy on welding ect. Recently I have decided to make some knives in the spirit of the old trade knives and buffalo skinners. My first two were from files. One is finished but I didn't temper it before I handled it. I used ironwood for the handles and now I am wondering if I might be able to draw that edge out a little without ruining the handle. Any suggestions? I also have another file blade hammered out and have not put a handle on so it should be easier. Oh, and I also have a couple Ulus I made many years ago from skilsaw blades and they wont take an edge either, didn't treat them either. I do not have a forge, I use my oxy/acetelene with a small rosebud clamped in the vise for a forge and a 4x6x12 block of D2 steel for an anvil. thanks
