Rage Broadheads are Leading the Evolution in Lethal Technology with award-winning designs and the number-one-selling expandable broadhead of all time. They feature SlipCam technology and revolutionary rear-deploying blades that fly like field points, yet are fully expanded at the moment of impact without significant loss of kinetic energy. Fail-safe by design, Rage's blade retention systems are second-to-none and include the patented Shock Collar and NC (No Collar) technologies, which securely hold the blades in place while not in use of during flight.
