Edging blades for constructing bevelled and angled contours for landscaping purposes

摘要

A bevelled edger blade has a base side attachable centrally to a conventional edger shaft. Ends of the base side having cutting edges are extended an equal distance in opposite directions from a blade axis at a central attachment orifice on the base side to vertical corners. An axial corner is positioned a select distance horizontally from the blade axis. Sloped edges of border channels of landscape areas are cut by cutting edges on angular sides intermediate the axial corner and the vertical corners on the three-sided edger blade as it is rotated by the conventional edger shaft. The angular sides can be straight for cutting straight slopes or arcuate for cutting arcuate slopes optionally. A blade brace can be positioned parallel to the base side between the angular sides. The vertical corners can be angled acutely for cutting landscape channels with acute angles between a straight surface and an opposite side. The vertical corners also can be rounded for round-bottomed edging or squared for cutting square bottoms of landscape channels. Deflector surfaces on rotationally aft edges of the sides of the blade can be provided for directing flow of cuttings out of the edging channels in a desired direction for collection or dispersement.
