hmm.. have you tried resin casting? if so, they could make interesting, steampunky pendants or charms..
actually you can probably cast about anything
like a keep away sign for your front door ^__^

hope i helped!

I cut the blade into two. From such pieces, I made a sign showing our House number and put it at the front gate. I stuck the pieces to a cardboard using an adhesive. It’s simple and elegant.

I know of two possible ways:
1) (DO NOT attempt to do this! Sticking electric wires in water is a very, very bad idea, and you may get hurt. The information here is for amusement only!) Back in Soviet times, young lads who had to live in dormitories built water heaters out of old razor blades. The idea was that pure water does not conduct electricity and, if you would stick in two blades with wire attached to each and a small gap between them, then the water would heat up as the electricity passes through it — just as a light bulb. So they took two blades and some matches to create the gap, put it all together and attached wires to each blade, making sure the blades don’t touch. Then they’d plug it in and throw inside a glass of water. A great way how to electrocute yourself, no? I’ve never done this and cannot repeat enough that you must not do this as well — or at least use a battery instead of plugging it in.
2) Another way that I also haven’t tried is to recycle these into low quality magnetic tape for reel-to-reel recorders (I read it in an old magazine). You should stick some inside a bottle of acetic acid and wait. They will dissolve eventually, and then the liquid is supposed to be slightly magnetic. Then you just take a paper tape, soak it with the liquid, dry it out and use in your reel-to-reel recorder. I’d love to hear if someone actually does it.
Other than that, I’m afraid they’re pretty useless.
