This was excellent practice, I made it from a coiled spring 12 mm thick (just under half an inch). So I had to do some straightening, some upsetting on the handle part, tapering it, upsetting on the other side and flattening it out. All the basic operations. Not much to look at but I do have some ideas for another screwdriver.
Also while I was waiting for it to heat I hammered some small hooks from old broken screws.
