Good practice, plus I'll be set if I get any letters on the other side of the metal detectors.
My friend gave me two sheathe knives that had gotten rusty on one side from being in the sheathes for at least twenty years. One is a big fat Pakistani bowie that's thick enough to grind the rust off, which I'm in the process of. I'll post photos when I'm done. This one is kind of cool: tight stag handle, hard, thin and very flexible blade and only light rust, which I'm taking off by hand because the blade is so thin. Too bad it looks like a bread knife, but it would be quel formidable in a between the ribs application. Think I'll stick with bread.
My next project, which I didn't put handles on before because it's too hard to drill stainless. But now that the epoxy only knives are holding up well, I'm just going to glue it and grind it. Then I have the last damascus blank, that I still haven't figured out how to handle.
