The mulching rotary lawn mower blade comprises a mounting section adapted to be attached to a lawn mower motor drive shaft and first and second sections extending respectively further outward from the mounting section and being respectively pitched upwardly and downwardly. First and second cutting surfaces are formed along at least a portion of at least one of the first and second surfaces. The first cutting surface is adapted to form grass clippings, while the second cutting surface has at least one cutout and is adapted to cut the grass clippings. The first cutting surface passes the grass clippings to the second cutting surface which recuts the grass clippings as the grass clippings pass through the cutout.
