I’ve been meaning to have a “touch mark” made to sign my work with… In the meantime, I tried my hand at making my own.
I took an old air hammer chisel, torched it until red hot and let it air cool. Once cooled, I put it in the band saw to cut off the chisel end, and faced it off in my lathe. With my layout fluid applied, I drew in my design. Next, I grabbed an old cold chisel ground it to a teardrop shape. Now that I had the the teardrop punch, I reheated the air hammer chisel to red hot, and punched in the two teardrop shapes. A little touch up grinding to make the design even and flat, and the I oil hardened it.
I’ve used it >20 times now, and it shows no wear, and looks as if I just finished it.
