FISH SKULL EXCHANGER SHANKS (EHS) is an innovative, articulated shank with a special shank-to-shank connector that allows you to change out different sections of your fly after the fly is tyed (example: Tails). It also can be used as an easy method to securely attach the main body to the front hook of your articulated fly. Triangular design reduces the gap between body segments to create tighter bodies. Loop Eye is stronger than a ring eye. Extended Wire Tags run the full length of the shank. This means there are now 3 parallel wire strands creating an even base platform to wrap the thread and materials along the entire length of the shank. SIZE: 20mm. $9.75/25-PAK
