INGROWN NAIL CORRECTION TOOL, METHOD FOR MANUFACTURING INGROWN NAIL CORRECTION TOOL, AND METHOD FOR IMPROVING DURABILITY AND CORRECTIVE FORCE OF INGROWN NAIL CORRECTION TOOL

摘要

The longitudinal direction (rolling direction) of a cold processed plate material 11 is indicated by the letter L and the width direction by the letter W. The layout direction of an ingrown nail correction tool material 13 is arranged such that the longitudinal direction of a material 13a of a body portion (corresponding to correction tool body 3) substantially corresponds to the width direction W, and the direction in which a nail holder portion material 13b (corresponding to nail holder portion 5) of a nail holder portion is formed substantially corresponds to a direction in which the cold processed plate material is processed. That is to say, the material 13 of the ingrown nail correction tool is integrally cut out from the cold processed plate material 11 and processed such that the longitudinal direction of the correction tool body 3 of an ingrown nail correction tool 1 is substantially perpendicular (direction W) to the direction in which the cold processed plate material 11 is processed; and the direction in which the nail holder portion 5 is formed substantially corresponds to the direction in which the cold processed plate material 11 is processed (direction L).
