Since the bolo itself is simply the bead that holds the two chains together, most issues with the bolo clasp have to do with broken chains. It also has the undesirable effect of leaving pieces of chain dangling from the bolo itself when adjusted to a smaller size. While the clasp itself is very sturdy, items that have thinner chains are prone to breaking from pulling the bolo. The two ends of a chain are drawn through the bolo, and moving the bolo up and down shortens and lengthens the piece.
Unlike the other clasps, the bolo is designed to be adjustable its sliding mechanism allows for the wearer to change the size of their jewelry.
The fifth type of clasp is most commonly seen on bracelets.
