If you've already racked it off the broken glass and little metal balls, I don't know how much more you can do. I wouldn't throw it out, as it there should be nothing toxic in there.
What stage was this at? If it was early primary, then I'd say aerate the heck out of it and maybe it'll lose that smell. Have you tasted it to see if the smell carries over to the taste?
