Today I learned how to properly peen pins. Sounds fun doesn't it? BTW, peening is the act of putting pins through two objects to lock them together. Have you ever heard of a ball-peen hammer? Well, that is what they are for. You put the pins through the materials and hit the pins with the peen end of the hammer and it causes the pins to swell inside the materials and mushroom out on the ends, The you can grind or sand the head off and you have two materials held together tightly.
Look at your kitchen knives, they may have been peened.
