A first blade wing ( 21 ) extends from the body portion ( 12 ) and has an upper surface ( 23 ) and a lower surface ( 25 ). A second blade ( 22 ) wing extends from the body portion ( 12 ) and has an upper surface ( 24 ) and a lower surface ( 26 ). A leading edge ( 41 ) is provided on the first blade wing ( 21 ) and a leading edge ( 42 ) is provided on the second blade wing ( 22 ), the leading edges ( 41, 42 ) being adapted to cut through a working medium during rotation of the blender blade ( 10 ). At least one wing flap ( 51, 52 ) extending outwardly, selectively from the first blade wing ( 21 ) and the second blade wing ( 22 ).
