A small metal rod used to attach a metal blade to its haft (as the handles of bronze daggers) or to fasten two sheets of metal together. Each end of the rivet is burred over (spread and flattened) by hammering after it has been passed through the two elements to be joined. Riveting is also a method of making joints in metalwork. The rivets are short metal rods which pass through holes in the parts to be joined and are hammered down on either side to hold the joint firmly together. In antiquity, riveting was used to make such artifacts as helmets or situlae.
