I recently added a new bucket to my arsenal. I labeled it 'SMASH' bucket. Not sure if this idea has been around or not, but it turned out to be a GREAT idea!
You know, all the little things that have copper or brass in them, but would take far to much time to recover. I toss them into my smash bucket. Put them into a burlap sack or something else heavy duty, and smash like hell with something heavy. I use a 12 lb. sledge hammer. Then you just run a magnet through the pile, then pull all the plastic out and all the goodies are left over.
Here is an example of some of the things I put in my smash bucket:
