A rivet is an apparel material that fastens fabric by pinching it between a female (head) and male (foot) part and then using a punch to crush and deform it. Because it can connect fabric more sturdily than sewing with thread, it has long been used primarily to reinforce areas that require a certain degree of durability, such as bag handles and pockets, but in recent years it has also become an apparel secondary material that is used as decoration for leather and apparel products.
