In an feat of stupidity I screwed up not one, not two, not three but four steel seed plates. One is a Coldbit and the others are Blockplates. The Coldbit I stamped a letter backwards, and the Blockplates I screwed up the position of punching the dots onto the grid. The end result is I now have 4 steel plates that have my seed phrase completed to various degrees, so now I need to know how do I go about destroying them?
