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.

Method of producing an outer blade for a hair cutting device

An electric shaver includes an outer blade having blade holes defined by a frame, and an inner blade provided inside the outer blade to move relative to the outer blade and cut body hair inserted into the blade holes. Circumferences of the blade holes of the frame are bent toward the inner blade so as to provide hair lifting portions having rounded portions in the frame, and the frame provided with the hair lifting portions is located closer to a skin than to a surface of the inner blade on a skin side.
