Rage Revolutionary SlipCam Broadheads utilize the rear blade deployment system. They feature a 2" cutting diameter and fly like a field tip. In flight Rage is streamlined so it flies like a field tip...upon impact, the SlipCam initiates and the blades slide back, deploy from the rear and by the time the blades impact, they are fully deployed. Rage Broadheads give you three advantages. They eliminate deflection, the blades are guaranteed fully deployed and there is no loss of kinetic energy. 3-Pack.
