Abstract:
A broadhead is formed from a ferrule, at least one blade pivotally coupled to the ferrule, and a biasing member positioned under the blade between the ferrule. The biasing member applies pressure upward to a trailing edge of the blade, which is prevented from pivoting forward beyond a pre-determined angle in relation to the ferrule by a point coupled to the ferrule.
