Claim:
A wear member for excavating equipment comprising: a front end, a rear end, and a longitudinal axis extending from the front end to the rear end; converging walls that converge toward the front end, side walls extending between the converging walls, and a socket that opens in the rear end to receive a base fixed to the excavating equipment; a hole extending through one of the walls for receiving a lock to releasably hold the wear member to the base, the hole including a pair of bearing surfaces for engaging the lock when in the hole to prevent release of the wear member from the base, one of the bearing surfaces being on each side of the longitudinal axis, and said bearing surfaces being inclined to each other so as to diverge in a forward direction; and a fulcrum for engaging the lock for pivotal movement between a hold position when the lock prevents release of the wear member from the base and a release position when the wear member can be released from the base, the fulcrum and the bearing surfaces being generally positioned along the longitudinal axis with the fulcrum positioned in front of the bearing surfaces.
