I found a very small little file with yellow rubber covering the handle. I found it in a EM. It looked like it was make to clean contacts on pins back in the day. I use it all the time now. Good fine. Nothing exciting or illegal. Quarters, nuts, etc. I work on appliances and you wouldn't believe some of the crap ive found in washers and dryers. People not cleaning out there pockets, and the sock monsters stash. He exists.
