One of my friends knocked one day and growled that he had locked himself out of his foot locker. I said maybe we could pick it, so we went around to his place and took a look. It was a beautiful piece of woodworking, glossy oak. He told me his granfather made. The lock was a padlock through a hasp. Picking was a definitely possibility, but any quasi-cubical object has six sides. So I turned it aound and discovered the hinges were face mounted. So we broke out his Swiss Army knife removed the hinges and he retrieved his key.
