  • Edging blade for powered landscaping edgers
    Patent number: 6302219
    Abstract: An edger blade assembly for cutting a beveled edge using a motorized edging machine. The edger blade assembly is a structure that includes a blade element. The blade element has two opposing free ends. Between the two free ends is a flat middle section, two diverging sections that extend outwardly from the flat middle section and two converging sections that extend between the diverging sections and the two free ends, respectively. The blade element is bent at an acute angle between the flat middle section and the diverging sections. The blade element is bent at an obtuse angle between the diverging sections and the converging sections, thereby forming a beveled blade structure from a single segment of steel.
