There is provided a rotary electric shaver which includes an external outer blade having a plurality of hair inlet holes on an annular shaving surface, an internal outer blade, a rotationally driven external inner blade having a plurality of small blades coming into sliding contact with a rear surface of the external outer blade, a rotationally driven internal inner blade, an external inner blade rest base, and an internal inner blade rest base. The external outer blade has a cylindrical guide ring formed on an inner peripheral side of an inner wall portion, and the external inner blade has a plurality of guides which come into sliding contact with an inner peripheral surface of the guide ring to perform radial alignment with respect to the external outer blade.

Slit blade block of an electric shaver of the present disclosure includes a slit outer blade having a plurality of outer blade pieces, a slit inner blade having a plurality of inner blade pieces, and comb provided outside the slit outer blade. Comb has a plurality of protruding portions protruding in a direction away from the slit outer blade. The plurality of protruding portions includes a plurality of types of protruding portions having different shapes. The present disclosure can provide a slit blade block having a comb that scoops lying long facial hair more easily, and an electric shaver provided with the slit blade block.

Provided is a method of producing an outer blade for a hair cutting device from a material including bars that each have a shape of a rectangular stick and are arranged at predetermined intervals. The material is placed on a base. Next, a first tool having a leading end that has a gradually increasing width in a direction away from the material is used to press at least one part of each of the bars in a direction from a counter base-side first face of each of the bars toward a base-side second face of each of the bars. An edge of the first face of each of the bars is caused to project widthwise and to move toward the second face to be farther from an intermediate part of the first face.

An outer blade for a hair cutting device, the outer blade being mounted to an end of a main body of the hair cutting device, includes bars that each have a shape of a rectangular stick and are arranged at predetermined intervals. The outer blade also includes, at a skin-surface-contact-side first face of each of the bars, an agent holding part configured to hold an agent that is a substance having a predetermined effect on a skin surface, the agent holding part being a surrounded recess heading from the skin-surface-contact-side first face of the bar toward an inner-blade-side second face of the bar. Thus, the agent such as foam or gel can be held by the agent holding part at the skin-surface-side face of the outer blade, and friction can be reduced between the outer blade and the skin surface by the agent held by the agent holding part.
