ABSTRACT:
An archery broadhead includes a centrally located ferrule around which are symmetrically mounted a plurality of blades, ideally three or more in number. Each of the blades has an outer edge which slopes rearwardly at a first, shallow angle from a needle-like point for maximum initial penetration, and then extends outwardly at a much steeper angle to cause maximum damage as the steeper angled portion follows the shallower angled portion into the opening which it has created.
