What is a "belt buckle"?

A belt buckle is a component of a belt that functions as the closure mechanism, holding the two ends of the belt together. It is typically made of metal, such as brass or steel, and can come in various shapes and designs. The buckle attaches to one end of the belt, and the other end passes through it to adjust the fit around the wearer's waist. The buckle can feature a prong, which hooks onto a series of holes on the other end of the belt, or a clasp that snaps into place. Some belt buckles are decorative, featuring designs or logos, while others are more functional and simple in design.
