A wear member for attachment along the digging edge of excavating equipment that includes ridges formed along its front working end. As the front end wears away, the tips of the ridges along the front of the wear member project forward to define a serrated penetrating edge. A serrated front edge is able to more easily cut into and through the ground. The ridges may be arranged in a generally axial direction along the front working end to present a reduced surface area to contact the ground for easier penetration. The ridges provide the front working end with sufficient rigidity and strength without unduly enlarging the surface area of the penetrating edge that initiates contact with the ground. |
