  1. My first attempt at a blade was a railroad spike knife (of course). My second attempt at a blade was a forge welded san mai from a railroad spike and some questionable coil spring. Having used up both of the spikes I had, a guy at work just gave me a bucket load more. I have a feeling that my next knife may involve a railroad spike. I really like the rustic feel of the spike as a handle contrasting a highly polished blade. A set of steak knives is on the cards. So far, everything has been an experiment and that's not likely to change. However, it's probably wise to start getting input from those more skilled in the art so that I may produce something that is fit for purpose. I recently acquired a random bunch of stock... mostly mild steel and 3xx stainless. Luckily, I did find a square bar of 440, although I don't know if it's A, B or C, so I guess I have to assume A? I'm thinking of repeating the san mai, only this time slotting in some 440 instead of the useless coil spring. With that in mind, I have a few questions... Are there any special considerations when forge welding mild steel to stainless? Assuming the 440 is A, is it even worth using or should I look for something else? Given that I don't know whether it's A, B or C, how should I handle the heat treat? Also, is there anything else I shoud be thinking about for this project?
