This one I managed to turn the taper on the lathe then heat to cherry and quench it became hard enough to resist a file so I heated to light straw and air cooled it is pretty tough but not brittle Should complement my collection of punches.
I also have some 3/4" rebar and a piece of 1 1/2" rebar but think I might make other plans of them.

I used to work in a mini mill and when we rolled rebar, the specs were very forgiving, as a result it was rolled from billets of various grades that did not meet their respective grade for whatever reason. As a result, there was some fine steel going in to the rebar, however some of it was so hard it would actually shatter on the concrete floor when dropped. Bottom line; it could be almost anything depending on where it came from.
All said, this is a very cool application, and there have been a multitude of rebar projects from all over!
