These things are alarmingly strong. The tops and bottoms are literally two inch (50mm) thick solid steel plates. Between them a custom arrangement of punches and dies stamp holes into sheet metal. They sold for a few dollars at auction, because unless you are the company that had them custom made to manufacture thousands of a very particular part, they are useless to you. They could be retooled to make a new part, but that’s a lot of work, for which there is little demand in my area.
