Articulated Flies catch lots of fish, but they can be a pain to tie with wire or backing as the connection. The Flymen Fish-Skull Articulated Shank solves this problem. You simply tie the back fly, finish it, clip on the articulated shank, and tie the gap shut. Finish your front fly, and you're good to go. No messing around with wire and beads trying to attach your hoks together, just snap it on and tie it shut, and you have a positive connection. Comes in three sizes to work for everything from trout to pike.
