TURKEY SPURSTurkey hunting requires a different approach than big game. Rather than passing completely through the bird, an effective turkey broadhead should transfer as much energy as possible into the target while still creating strong cutting action. The VPA Turkey Spur was designed specifically with this goal in mind. Rear Spur Blade Design At the rear of the head, sharpened Spur blades create a 1 1 8" cutting diameter that delivers aggressive cutting action.
