Swing'r™ is a broadhead so unique, it was granted a U.S. Patent. It was designed for bowhunters who are shooting lower poundage bows and who are forced to shoot small cutting width broadheads in order to achieve maximum penetration. With the patented design of the new Swing'r™ these bowhunters can now shoot a large 1 1/2 inch cutting width broadhead, without impeding penetration!How does it work? As the Swing'r™ strikes the animal, the retaining o-ring at the back of the blade either breaks or slips back along the arrow shaft, allowing the blade to swing like a pendulum. When the blade encounters heavy resistance like bone, it simply swings to one side. After the resistance is overcome, equal pressure on the blade straightens it out, and it continues penetrating through the animal like a conventional broadhead. The full 1 1/2 inch cutting width is always maintained. The strong stainless spring steel blade is easily replaced or sharpened..So if you are one of the many bowhunters shooting a lower poundage bow, try the Swing'r™ 100 grain pivoting blade broadhead!
