ABSTRACT:
The present invention relates to a rotary lawn mower blade that is designed to make multiple cuts of grass or other material being cut as the lawn mower blade is advanced over a cutting area. This is achieved by providing a generally upturned cutting edge about each end of the lawn mower blade. Because the cutting edge is inclined outwardly and upwardly, it follows that the grass or other material being cut will be progressively cut and recut as the mower blade passes over underlying material to be cut.
