ABSTRACT:
The present invention comprises a rotating blade, in particular for the comminution of food materials, which is adapted to be attached to an operating shaft and which includes at least two blade supporting arms which extend radially from a mid-portion. The blade supporting arms each have a knife-edge with cutting edges on a free edge in the direction of rotation. According to the present invention, the knife-edge of the one supporting arm is directed upwardly and the knife-edge of the other supporting arm is directed downwardly, and in the area of the knife-edges the legs are profiled such that a portion projecting from the surface of the supporting arms is formed. The projecting portion is limited by the knife-edge on the one side and by a chamfered surface extending outwardly to the cutting edge on the other side. The knife-edge and the chamfered surface enclose a chamfer angle. A good cutting effect and mixing action is achieved thereby, and the handheld blender can be manufactured and operated particularly easily.
