A selection of tie clips, mostly from the early to mid 20th century. A tie clip (also tie slide, tie bar, or tie clasp) is a clothing accessory that is used to clip a tie to the underlying shirt front, preventing it from swinging and ensuring that the tie hangs straight, resulting in a neat, uniform appearance.
The paper clip seems like a simple solution to binding loose papers, but it wasn't invented until the creation of cheap steel wire. Steel wire is strong enough to hold the shape but bendable enough to be twisted into a clip and stretched over stacks of paper. Paper clips are traditionally made of galvanized steel wire, but others are made of brass, stainless steel, vinyl-covered wire or even plastic. Before paper clips, people bound stacks of papers together with straight pins or tied them together with ribbon or string.
