Abstract: A dual concrete edging tool apparatus comprises first and second, generally conventional edging tools, each of the edging tools comprising a flat plate having a narrow edging lip depending therefrom and a rigid plate, the first and second edging tools being mounted by longitudinal angle irons to the under side of the plate so that both of the edging tools have their depending lips in parallel opposition with one another, one of the edging tools being mounted to transversely-oriented slots in the plate to enable the distance between the depending lips of the first and second edging tools to be adjustably varied from zero inches to at least about two inches. An edging tool back-up element is mounted to the plate to be in contact with upper surfaces of both the first and second edging tool and to thereby enhance the rigidity of the apparatus. The apparatus includes an elontate, pole-like operating handle pivotally mounted to upper regions of the frame in a generally central region thereof.
