Snaps & Swivels are the little metal clevises, ball bearing swivels, lure snap, and other small wire devices used to create a rig. Anglers utilize the ball bearing swivel to help prevent line twists, snap swivels for better bait movement and user-friendliness. Swivels also help connect to line types or when constructing fishing rigs. While they might seem minor, and you won't always need them, there are times when having the right fishing swivel will significantly improve your overall fishing experience.
