If you have a dremel tool and it's not sheared off too deep you can cut a channel into the sheared off remains and then take a flat head screwdriver to back it out with.

+1 on Everhard's idea. Also, like Moss said a chisel and hammer. However, I've always used a pointed punch instead of a chisel. It may bite better because there isn't a lot of surface area to work with.
