Abstract: A foodstuff slicer which is particularly useful for shaving ice, frozen fruits and the like is disclosed. The foodstuff slicer is provided with a rotor composed of a downwardly diverging hood, a plurality of carrier-arms and a boss connected to a vertical driving shaft. The carrier-arms extend radially and upwardly in spaced relation with a wall of a conical case which diverges upwardly. A cutting blade is attached to a upper portion of the conical case. Centrifugal forces acting on lumps of foodstuff become nearly maximum at the position of the cutting blade to slice the foodstuff steadily.
