Abstract
A ground engaging member that engages a work material to dig into the work material includes a member body extending from a leading end to a trailing end, the member body having an internal surface defining a cavity therein, the cavity having a concavity that faces away from the leading end along a longitudinal direction, the longitudinal direction extending from the leading end to the trailing end; and a first wear sensing body embedded in the member body between the cavity and the leading end along the longitudinal direction. The member body is fabricated from a ground engaging tool (GET) body material having a GET body material density. The first wear sensing body is fabricated from a wear sensing body material having a wear sensing body material density that is not equal to the GET body material density.
