Abstract
Provided is a broadhead for an arrow having a shaft with a shaft bore. The broadhead comprises a ferrule and a plurality of blade members. The ferrule has a mating end and a tip end with a plurality of convex ridges being equiangularly spaced around the ferrule such that the ferrule has a tri-oval cross section. Each one of the ridges has a blade groove formed therein for receiving one of the blade members. The blade members each have a base portion that is shaped complementary to the blade groove so that the blade member may be axially insertable into the blade groove. The broadhead includes a shank extending outwardly from the mating end and which is threadably engagable into the shaft bore. An O-ring mounted on the shank is captured between the shank and the shaft bore when the broadhead is secured to the arrow at the mating end.
