Fish-Skull Next Generation Articulated Shank. New design of shanks incorporating a new triangular rear loop. The triangular loop is easier to hold in the jaws of the vise. The shorter rear loop also brings the articulated segments closer together with a more uniform shape and taper. The new design also features a front loop eye rather than a ring eye. Making a stronger connection and less chance of failure. The loop eye tags extend back along the entire length of the shank, making a uniform tying platform.
