thanks for the advice chris... yeah i def. had some scale problems. i don't have a wire brush yet (going buy some supplies today), and i'm using a chunk of railroad rail for my anvil, which happens to be a little dented where my grandfather used it, so there was a lot of scale that was built up on it. i dunno if i'll polish it or not, cuz i know that rebar is too low carbon to really make a great knife. this was just an attempt to get a shape without grinding, and good practice with learning how the metal behaves when heated. thanks for the kind words!
