Abstract: A mulching blade for rotary lawn mowers having a centrally-disposed mounting point and two cutting arms extending outwardly therefrom, each cutting arm having a leading edge and a trailing edge, the leading edge being sharpened to form a cutting edge for severing grass, at least one of the arms being angled downwardly from said trailing edge to said leading edge to induce grass clipping upwardly for subsequent engagement with the cutting edge of the second cutting arm in order to finely mulch the grass clippings. Each cutting arm is generally horizontally planar proximate to the cutting edge to allow for ease in resharpening.
