Abstract
An arrowhead for an arrow that utilizes a blade locking ring for retaining and releasing a set of expandable blades. The arrow has a slotted ferrule for rotatably attaching a set of expandable blades. Each expandable blade has a ear having a notch and a rim for holding the blade locking ring in a retaining and releasing position, respectively. The rim is dimensioned in view of the width of the blade locking ring, so that outward projections are minimized. Operationally, the tip of the arrow penetrates a given distance before actuation of the releasing mechanism, so that the expandable blades open within the body of the animal. The skin of the target displaces the blade locking ring from the notch to the rim, causing the blades to pivot outward. As such, the impact force is maximized to inflict greater damage inside the animal, therefore increasing the chances of getting a kill. The blade locking ring is pushed onto the arrow shaft for reuse by the hunter.
