Anglers Image Tippet Rings Unlike a blood knot or a double surgeons' knot, the use of a tippet ring allows the angler to connect a tippet that is significantly different in diameter than the end of the leader. Think connecting 7X tippet to 3x leader... The advantage to the angler is that you can rapidly change tippet diameters without the need to drastically rebuild or restructure their leader and you preserve the length of your original leader. 10 Rings per pack
