A wear indicator (118) is provided for a wear member (16) of a machine wherein the wear member (16) is subject to wear during use of the machine. The wear indicator (118) may include a plug member configured to be positioned in a region of the wear member (16) subject to wear. The plug member may be oriented with a central axis extending in a direction substantially parallel to a direction of wear of the wear member (16). The wear indicator (118) may include a plurality of perceptibly different and distinct axial cross sections (118a, 118b, 118c, 118d) taken perpendicular to the central axis of the plug member in axially spaced planes along the central axis.
