A clasp is a device used to fasten two or more objects together. It is usually made of metal and has a hook, bar, or spring mechanism that can be opened and closed to securely hold objects in place. Clasps are commonly used in jewelry-making to secure bracelets, necklaces, and other items. They come in a variety of shapes and sizes, from simple S-shaped hooks to more intricate designs featuring gems or enamel. A well-designed clasp not only keeps the jewelry in place but can also add to its overall aesthetic appeal.
