ABSTRACT:
A broadhead for an arrow has a ferrule and a pair of blade members. Each blade member has a first end that is pivotally interconnected with the ferrule body and an opposite second end. The blade members each have a retracted position and an extended position. A biasing member biases the blade members toward the extended positions and is the only element operable to hold the blade members in the extended position.
