Cliff Zwickey designed this barbed broadhead in 1939 and had made only a few thousand when some states banned them, causing production to cease and making these a collectors item. Zwickey Archery has decided to reintroduce these superb broadheads. Patented Zwickey construction puts bulk of high carbon steel up front for bone busting strength. They are then individually heat treated, with no cut-outs to impede penetration. The Cliff Zwickey Screw In measures 2 13/16" x 1 3/16", and weighs 175 grains. Sold 3 per pack. NOTE: Not legal for hunting in many states.
