Abstract
A dual blade assembly for a lawn edger, the assembly comprising first (140) and second (142) generally rectangular blades arranged in a substantially cross shaped configuration for rotation about a substantially central axis (R). Each of the first (140) and second (142) blades having a central region between two end cutting regions, at least one protuberance (144) in the central region and at least one recess (148) in the central region. The promuberance(s) (144) of one of the first (140) and second (142) blades is adapted to engage with the recess(es) (148) of the other of the first (140) and second (142) blades to counteract relative movement between the first (140) and second blades (142) about the rotational axis (R).
