The clothespin is a fastener designed to hang clothes up for drying, usually on a clothes line, although there are many different designs. These clothespin are manufactured very cheaply by creating two interlocking plastic or wooden prongs, in between which is often a small spring. David M. Smith invented this design in 1853. When the prongs are pinched at the top they open up, and when released the spring draws them shut.
The Shakers were the first to invent the clothespin. The older design did not use springs but was fashioned in one piece. Clothespins, also called pegs, are used to play a game called pegging in which players secretly attach pegs to an oblivious victim. There are many uses for the clothespin including closing a bag, hanging clothes on clothes lines, and attaching various things together.
