A middle cutter of a shaver includes a comb, comb mounts, a cutter, a cutter mount, a pair of spring plates, and a pair of steel balls for holding the cutter mount in a floating manner. The comb has an upper surface that includes a plurality of isolated openings. Each comb mount includes a retaining groove that retains the spring plates. The cutter, which includes a plurality of cutting grooves, is arranged in tight contact with an inner surface of the comb, such that the cutting grooves act with the comb openings to providing the shaving action. The steel balls are movably received on the spring plates such that upper portions of the steel balls are biased against the cutter mount by the spring plates so that the cutter mount is held in a balanced manner and maintains tight contact between the cutter and the comb.
