A blending appliance is provided including a motorized base, a blending container, and a blade assembly fitted into an opening of the blending container and rotatably coupled to the motorized base when the blending container is mounted on the motorized base. The blade assembly includes a lower blade element disposed on a spindle performing blending operations on ingredients at a lower end of the blending container; and an upper working element disposed on a shaft spaced apart from the lower blade element, and including an upper working portion and a lower working portion spaced apart from the upper working portion. The upper working portion acting to reduce cavitation in the lower blades element during the blending process.
