  • Patent number: 4090730
    Abstract: This invention is a hand tool, for weeding or cultivating, consisting of angled handle attached to a blade with a serrated edge. The angle of handle and blade, and the cut of the serrated edge, combine to enable the user to easily slide the blade horizontally under the earth surface and pull the weeds out, rather than cut them off. The blade, according to the depicted embodiments, is made of spring steel, whereas the handle is made of plastic. As disclosed herein only by way of example, the handle supporting shaft is made of forged steel. The shaft is bent at an angle to dispose the blade in a horizontal plane.
