A mounting base for removably coupling a wear member to a tool may have a generally planar first base portion, which may have an inward surface configured to be attached to the tool. The mounting base may also have a generally planar second base portion extending from the first base portion in a direction generally perpendicular to the first base portion. The second base portion may have an inward surface configured to be attached to the tool. The first base portion may define an opening including a notch-shaped portion and a rectangle-shaped portion.
