Abstract
A cutter for use in a blender includes a central hub portion defining a horizontal plane. First and second pairs of blades extend outwardly from the hub portion. The first pair of blades is oriented on opposite sides of the hub portion and the blades lie in substantially the same horizontal plane as the hub portion. The second pair of blades is oriented on opposite sides of the hub portion and the blades extend upwardly from the horizontal plane of the hub portion, and further wherein the angles of upward extension of each of the second pair of blades is asymmetric. Further, each blade of the first set of blades has a cutting edge and trailing edge, and each blade of the first set of blades is pitched so that there is a downward slope from the cutting edge to the trailing edge.
