The HS-1 is designed to increase the quality of your epoxy-head flies and jigs by rotating them at the optimal rate while the epoxy is curing. This produces perfectly shaped bodies and frees up your hands to tie or coat more flies. The Head Spin-large five-inch wheel will rotate well over a dozen flies, and uses a sturdy and unique patent-pending spring design to securely hold flies from size 6 to 6/0. The unique spring wheel holds your fly hook between its coils, which act like a series of 200 or so mini vises. The spring wheel also features a special slip-clutch design that allows you to grab, stop and reverse the wheel as you add flies, jigs or epoxy.
