A lobster clasp is a type of fastener commonly used in jewelry, particularly in necklaces and bracelets. It is named for its resemblance to a lobster's claw, featuring a spring-loaded mechanism that allows it to open and close securely. This design makes it easy to use while providing a reliable hold to keep jewelry pieces from falling off. Typically made from metals like stainless steel or brass, lobster clasps come in various sizes and finishes to match different styles of jewelry. They are favored for their durability and strength, making them suitable for both everyday wear and more delicate pieces.
