ABSTRACT:
An anti-wedging, controlled deployment broadhead with an over-center of gravity blade geometry for bow-hunting that has the ability to penetrate bone and soft tissue deeply before deploying its blades while conserving the highest possible amount of kinetic energy in flight and at target. The inventive device includes the one-piece body, specially aligned and faceted cutting tip, blades, O-ring, and set screws. The blades have independent pivots that also act as travel limiters, are arch shaped with very sharp leading edges and a J-shaped lever. The center of gravity of each of the blades is oriented so as to insure retaining each blade in its respective retracted position during acceleration and assisting in deployment thereof during deceleration. The device with its special body and blade geometry now allows for more energy and blade area to be delivered to the vital organs of game to facilitate a faster and more humane harvest.
