This handy line threader makes 50+year-old eyes young again! It works on a wide range (size 6-22) of fly sizes. Simply select the "small" or "large" end of the Quik Tye, clip the eye of the fly in place, and thread the tippet through with no hassles. The Quik Tye has a pocket clip and a lanyard ring for easy attachment to a vest or pack.
