ABSTRACT:
A sheet metal tool such as a garden rake or garden cultivator of special one piece metal construction. The garden tool such as a rake or the like is comprised of a flat body of steel which is pressed in a manufacturing operation to provide a body portion having reinforced rib strengthening structure including a continuous flange along each side thereof and a head portion bent over at right angles to the body portion and having particularly strong tines made possible by a generally U-shaped cross section at the rear but with the side walls being pressed solidly together at the tines ends to provide strength and rigidity and avoid accumulation of debris and thereby minimize rust contamination.
