 people used what was called a pinking iron to punch out a decorative hem on a garment. So it had a zigzag pattern, and what you did was you took the cloth and you put it over a hard surface, and in between the hard surface and the cloth, you had this pinking iron that had a zigzag pattern on it, and then you hammer it with a mallet, and that cuts that little zigzag pattern. But what a pain to do that, right?
