Abstract
Abstract An arrowhead having two cutting edge portions extending rearwardly from their point of attachment to a frontal blade portion, and spiraling about the axis of an arrowhead ferrule. Each cutting edge portion encompasses 180* of the ferrule so that acting together they cut a plug from the flesh of an animal target. At their rear points of attachment the cutting edge portions are fastened by a mechanical interlock to flanges which extend radially outwardly from the ferrule. The cutting edge portions may be made replaceable.
