Abstract
A wear member includes a front end and a rearward end, the rearward end having a cavity formed therein. The cavity may include a forward portion, a rear portion, and an intermediate portion. The forward portion may be disposed toward the front end and the rear portion may be disposed toward the rearward end. Each of the rear portion and the forward portion may include at least four surfaces. Each of the four surfaces of the rear portion may converge toward a longitudinal axis of the wear member at a first converging angle, and each of the four surfaces of the forward portion may converge toward the longitudinal axis of the wear member at a second converging angle. The intermediate portion may extend between the forward portion and the rear portion and may include a different number of surfaces in cross-section than the forward portion and the rear portion.
