ABSTRACT:
A blade-opening arrowhead wherein at least one blade, preferably two blades, are pivotally mounted with respect to a blade carrying body. A bias force is used to urge an engagement member against a corresponding blade. The bias force is preferably selected so that each blade remains in a normally closed position during flight or during handling of the arrowhead, but yet responsively and quickly moves to a fully open position upon impact or when a sufficient opening force is applied to the blade.
