ABSTRACT:
Two pairs of blender blades for crushing ice, one of which pairs extends upwardly and the other of which extends downwardly. The blades of the upwardly-extending pair are similar in size and shape; but one of the pair is at a sharper angle to the axis of rotation than is the other. The leading edges of this pair are involute. i.e., are convex towards their base and concave toward their tips. The downwardly-extending pair of blades are similar in shape and size and are at the same angle to the axis of rotation.
