The Mustad stainless steel split ring has a wide range of applications, from intensive sea fishing to fine presentation of a small lure. The Mustad range covers it all. They are most often used to attach lures to a leader or hooks to a lure. Sometimes it may be necessary to replace broken rings on your lure, or your new lure may not come with one. Adding a split ring to your live-bait hook will give a much better natural bait action in the water. When choosing a split ring, always opt for the smallest possible, guided by breaking resistance. This will give the best performance and presentation. For use in saltwater or freshwater.
