CA 2234966

A blade edge with increased durability and a reduced cut force and a method for manufacturing the same. The blade edge is thickened by depositing a coating or grinding. A thin film having a low coefficient of friction, such as amorphous diamond, is then applied to the edge. An additional layer of a lubricious polymer may then be applied. The resulting blade edge has a significantly reduced cut force over existing razor blades and also has greatly increased durability.

Cette invention concerne un fil de lame de rasoir à durabilité améliorée et nécessitant une force réduite, ainsi que la méthode de fabrication correspondante. Le fil de la lame est épaissi par dépôt d'un revêtement ou par meulage. Une pellicule mince à faible coefficient de frottement, composée par exemple de diamants amorphes, y est appliquée. Une couche de polymère à haut coefficient de glissance peut aussi y être appliquée. Par rapport aux lames existantes, le fil de lame ainsi obtenu permet de réduire sensiblement la force devant être appliquée pour couper la barbe et se caractérise par une durabilité accrue.
