Abstract

This invention provides a shortening production steps method for manufacturing comb blade used in hair thinner cutting scissors in which the peripheral edges of comb grooves are chamfered and rounded and the combing scissors manufactured by the method, which is mainly consisting of: the comb blade having comb teeth arranged parallel with each other on both sides of the comb grooves is manufactured by a sintering method for sintering a molding formed of the material of the scissors. The molding is formed in the same shape as the comb blade, and an excess width portion (121) is provided to the blade tip side of the comb blade to form the tip of the comb blade wider than the comb blade. The comb grooves are formed leaving the peripheral edge of the molding by the excess width portion. The method is characterized by sintering the molding thus molded and removing the excess portion (121) from a sintered body (120) thus sintered to form the tip (123a) of the comb teeth (123). The molding may be formed in such a shape that the peripheral edges of the comb grooves are chamfered. Also, the molding may be formed by molding the band-like recessed parts extending from the base end to the tip of the molding as splitting at the lateral center of the blade rear part of the molding and the lateral both sides of the molding other than the recessed parts at the blade rear part may be formed such that are pushed out by push-out pins. The scissors are manufactured by using the above method.
