Each of the blades has a non-planar elongated body (12) with generally planar portions (14,16), and an arcuate working edge (20) having teeth (22) which extend in a direction generally parallel to the direction of hub rotation. The working edge includes two elliptical-shaped segments (24,26). <IMAGE> |
