I think you'r referring to dental picks. Harbor Freight sells sets for a few dollars. They're even called dental picks. Watch your fingers, they're really sharp.AnnivSpeCpe said:What you need is a tool that you can make to use like a lock pick. Something similiar to an ice-pick that has a point but small enough in diameter to go into the key slot. Then bend a small "hook" into the pointed end and go in and try to work the piece out. You should be able to get a bite on the broken piece on the toothed side of the key. Or, use two such tools and work from both sides of the key at same time. Good luck, John
