摘要

Provided is a method of producing an outer blade for a hair cutting device from a material (100) including bars (101) that each have a shape of a rectangular stick and are arranged at predetermined intervals. The material (100) is placed on a base (200). Next, a first tool (301) having a leading end (310) that has a gradually increasing width in a direction away from the material (100) is used to press at least one part of each of the bars (101) in a direction from a counter base-side first face (111) of each of the bars (101) toward a base-side second face (112) of each of the bars (101). An edge (113) of the first face (111) of each of the bars (101) is caused to project widthwise and to move toward the second face (112) to be farther from an intermediate part (114) of the first face (111).
