Abstract: 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.
