Lobster claw clasps are a traditional style clasp that’s very popular for finishing necklaces, bracelets and anklets. They have a loop at one end for adding a jump ring to or for threading the stringing material through which will then get secured with a crimp. The other end of the lobster clasp also known as a lobster hook has a fastener that is kept shut by a spring mechanism. To open and close the clasp you push on the small lever which opens the arm, which snaps shut once the lever is released making this a very secure form of clasp. Available in Sterling silver or silver plated brass.
