I'm working on a knife from a trap spring. I have it looking about how I want, and have some mesquite handles made. I put it all together with brass pins for shaping the handles, but now it's almost time to glue it all together and peen the pins. I'm wondering if mild steel pins wouldn't look better on this knife, since I left alot of the forge finish on the steel, polishing only the bevel and swage. Any opinions? I've done a knife or two with brass pins, but haven't used mild steel yet. Could I find a nail the right diameter, or maybe rod stock from the big box store? Do steel pins peen easily?
