ABSTRACT. Dry shaving apparatus. The invention relates to a dry-shaving apparatus comprising a housing with a holder for a shear plate formed with hair- entry apertures and comprising a cutter which is rotatable about an axis of rotation, which cutter comprises a carrier with cutting elements which are movable in a substantially radial direction relative to the carrier, which cutting elements comprise cutting edges at their radial ends. During rotation of the cutter as part of a revolution each point of the cutting edge of a cutting element follows a constrained path defined by the shear plate and when the ends are clear of the shear plate a free path in the form of a first circular arc. The shear plate comprises a central portion which in radial sectional view is curved in conformity with a circular arc having a radius smaller than that of the free path. The shear plate also has peripheral portions where the shear plate adjoins the holder. At the location where the free path changes into the constrained pathbetween the peripheral portion and the central portion. the shear plate is formed with a transitional portion having a larger radius of curvature than the central portion.
