Well, I don’t have a picture of my napping tool, but, it just a 1/2” piece of mild steel square stock dressed off to a cross pean on one end and left square on the other, with a 1/4” bolt threaded into it for a handle. I did make an antler tine handle to cover the bolt shank. I know it bigger than most, and iron instead of brass, or copper, but it works great, and I don’t have to reshape it all the time. After trying to get many modern flintlocks to shoot that had mild steel, or iron frizzens I figured it wasn’t likely my mild steel hammer was going to set anything off.
