Assuming they are hardened, and that's why you can't bend them in place to try and "fix" it, you should be able to heat them with a torch to soften the metal (and relieve stress) and allow you to bend it. Course I guess you could just chalk them up as used up and get a new pair.

Id have to say thats the first time I've heard of the metal breaking in them. Every other report I've heard of them breaking it was the rubber that finally let go.
