ABSTRACT:
A hunting broadhead arrow comprising a hollow body or ferrule having a plurality of circumferentially spaced slots extending through the sidewall thereof for receiving a flat substantially triangular shaped blade member in each of the slots. The shank of the point member of the arrowhead extends slidably into the interior of the body and carries a plunger member in the inner end thereof. Each blade is retained in a normal contracted or retracted position with respect to the body by suitable snap ring members, and each blade is provided with a recess on the inner edge thereof for engagement with the outer periphery of the plunger member in the retracted position of the blades. Upon impact of the arrowhead, the point member is moved in a direction toward the body for moving the plunger member rearwardly within the body whereby the trailing ends of the blades are moved radially outwardly to an extending position for the blades, thus increasing the cutting diameter of the blade upon impact to increase the efficiency of the arrowhead.
