An arrowhead assembly provides for removable installation of one or more flat, planar, laterally symmetrical knife blade type arrowhead blades to an arrowhead body. The arrowhead body includes a series of slots in its leading end, and a slotted ring formed rearwardly of the leading end. The blades each include an open central area and a pair of opposed tangs extending outwardly and rearwardly from their trailing edges. A lock washer includes a series of inwardly disposed tang clearance slots and catches, for securing the blades to the arrowhead body. The blades are assembled on the body with the tangs extending rearwardly of the retaining ring, with the washer placed over the tangs and turned fractionally to place the catches between the retaining ring and tangs, thereby holding the blades in place on the body. The present assembly precludes requirement for tedious threading of components.
