Rolling Swivel [Jun 28,2017]
fishing swivel is a small device consisting of two rings connected to a pivoting joint. The device is usually made of metal, and the pivoting joint is usually ball- or barrel-shaped. The line from a rod and reel is tied to one end, and a length of fishing line, often terminated by a hook, lure or sinker, is tied to the other. The main purpose of the swivel is to allow the line to untwist during line retrieval, preventing undesirable tangling.
