In a rotational lawn mower it sometimes uses a mulching blade known to have a single cutting edge. The invention provides an improve mulching lawn mower blade, to mulch in a faster time frame. The multi-edge blade includes more than one cutting edge on either ends of t he blade, where the forward most edges on either end acts as the regular grass cutter to cut in the same plane as the mower blade horizontal rotation. The second and third edges are created by cutting the flat surface of the blade at two places on either ends, where the two cutting edges thus created are bent up at an angle in separate rotational planes. The cuts made on the flat surface is do ne at an angle to the perpendicular to produce a sharp leading edge, these two additional edges cu ts the grass clippings into smaller pieces.
