Based upon the original Articulated Shank created by Flymen Fishing Company in 2011, the Articulated Big Game Shank is optimized for both strength and fly length allowing you to tie big flies that can hook, hold and land large, predatory game fish. Heavier gauge wire that can handle more materials and hold bigger fish. Extended length, with over sized front and back loops for bigger hooks. Offset front and back loops for inter connectivity. Three lengths, 28mm, 40mm and 80mm. Stainless steel for saltwater flies. 12 stainless steel shanks per packet.
