Abstract

L'invention porte sur un coupe-ongles, lequel coupe-ongles tient compte de la forme de l'ongle humain et il ne provoque pas de déformations non naturelles à l'ongle lors de la coupe de l'ongle, et qui est apte à couper l'ongle tout en douceur. Ce coupe-ongles coupe un ongle en amenant un bord de coupe formé sur une pointe d'une lame de coupe proche d'un autre bord de coupe formé sur une pointe d'une autre lame de coupe, les bords de coupe étant disposés de façon à se faire mutuellement face, en disposant l'ongle à couper entre les deux bords de coupe, et en amenant les bords de coupe en contact entre eux. Le premier bord de coupe et l'autre bord de coupe possèdent chacun, dans une direction perpendiculaire à la direction dans laquelle chaque bord de coupe se déplace de façon à ce qu'ils se rapprochent l'un de l'autre, une partie en ligne droite qui fait face à celle de l'autre et qui s'étend parallèlement à celle-ci et une partie incurvée qui se poursuit à partir de la partie en ligne droite et qui s'incurve et qui s'étend selon une courbure correspondant à celle de l'autre.
