PROBLEM TO BE SOLVED: To provide tweezers in which both clamping surfaces are in contact with each other entirely and can strongly clamp hair without letting the hair slip or break at the time of clamping the hair with the clamping surfaces and removing it, while conventional tweezers have an elastic member covering clamping surfaces, however the elastic member breaks or separates from a metallic main body during use and it is very difficult to clamp one hair from lots of the hair or the like since the distal end of the elastic member is thick and such tweezers are not practical, or tweezers having clamping surfaces formed with many recessed grooves in a crossed fashion are used, however it is not easy to engrave many recessed grooves at the clamping surfaces since the vertical width in front and back directions of the clamping surfaces of the normal tweezers is short and such tweezers become expensive. SOLUTION: A method is disclosed for manufacturing the tweezers provided with the clamping surfaces facing each other on end parts for clamping the hair by closing the clamping surfaces and removing it, wherein by generating discharge between an electrode and the clamping surfaces by electric discharge machining, the clamping surfaces provided with many fine recessed parts are formed.
