Abstract:
An expandable arrowhead having a blade-carrying body with a slot that houses at least one pivotally mounted blade. Each blade can be pivotally mounted about a shaft. In some embodiments, the shaft is fixed with respect to the body. In some embodiments of this invention, a spring element positively holds one or more blades in a closed position or a retracted position, particularly during extreme forces encountered when launching an arrow from an archery bow, such as a compound archery bow. The spring element of this invention can be used to improve blade opening capabilities of conventional blade-opening arrowheads or broadheads.

Claim (Index 10):
An improvement to a blade-opening broadhead having a blade movable with respect to a body, the improvement comprising:\n a first blade and a second blade each mounted within an opening of the body to pivot with respect to each other and with respect to the body, the first blade and the second blade moving between a retracted position and an expanded position, and a spring element contacting the body, the first blade and/or the second blade to apply a retaining force holding the first blade and the second blade in the retracted position during a launch and/or a flight of an attached arrow shaft and the retaining force allowing the first blade and the second blade to move from the retracted position to the expanded position upon impact with a target.
