Any ideas what this could be? About 3 inches length. Light ... likely made of aluminum, not steel. The end is indented as if it could be a punch. Outside seems to have threads.

I'm in for the ride! That little tit at the end of the slot is probably where the spiral fits but would have to be held tight to keep it from popping out
looks like nail punch or rivet set grove around outside is looks like Acme thread perhaps from shaft it was made from. May have been made a lath, indentation is for dead center. was just a practice piece or demo.
Thanks for ideas. The "threads" do appear to have been custom cut ... I had in mind the threads served some function but could be just decoration. I will add it to my tool box as a punch ...
they may help with grip, ACME threads are square cut for high load, most vices have them.
