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 5):
The blade-opening broadhead according to  claim 1 , wherein the spring element has a retaining force applied to the at least one blade.
