Abstract

La présente invention concerne un rasoir à double tête, et plus particulièrement un rasoir à double tête dont la tête présente deux côtés, un côté de la tête présentant un nombre relativement important de lames agencées de façon plus dense, et l'autre côté de la tête présentant un nombre relativement moins important de lames agencées de façon moins dense. Un utilisateur peut par conséquent effectuer un premier rasage au moyen des bords de coupe des lames agencées de façon moins dense sur ledit autre côté de la tête, et peut réaliser un rasage de finition au moyen des bords de coupe des lames agencées de façon plus dense sur ledit côté de la tête. En outre, les lames et les éléments d'écartement agencés sur la tête présentent des structures particulières permettant le retrait facile et efficace de débris pendant le nettoyage du rasoir.
