The inside inner-cutter members make a sliding contact with the inside outer-cutter members, and the outside inner-cutter members make a sliding contact with the outside outer-cutter members. The outside outer-cutter members are free to tilt and free to move with respect to axes of outer cutter holes made in a shaver head. The inside outer-cutter members are free to tilt and free to move with respect to the axes of the outside outer-cutter members. The inside inner-cutter members are rotated with their axes being coincide with the axes of the corresponding inside outer-cutter members; and the outside inner-cutter members are rotated with their axes being coincide with the axes of the corresponding outside outer-cutter members.
