Abstract

1. Una cuchilla de afeitar dotada de una punta de filo cortante de acero inoxidable, cuya forma de la sección transversal, hasta una distancia de 40 mim desde el filo extremo, está definida por la ecuación: w=adn en la que w es el grosor de cuerda en mim desde un filo extremo de la hoja; a es un factor de proporcionalidad no mayor de 0,8 y n, es un exponente que tiene un valor del orden de 0,65 a 0,75. 2. Una cuchilla de afeitar de acuerdo con la reivindicación 1, modificada enque al menos de punta de la hoja o cuchilla es de un material que tiene un límite de elasticidad más alto que el del acero inoxidable, y en la que la anchura w obtenida partiendo de dicha ecuación se reduce en proporción inversa a la raíz cuadrada de la relación del límite de elasticidad del material más duro respecto al del acero inoxidable. 3. Una cuchilla de afeitar de acuerdo con la reivindicación 1, modificada en que la punta del filo de corte está recubierta con un material que tiene un límite de elasticidad mayor que el del acero inoxidable,en la que la forma de la sección transversal de la punta esta¿definida por la ecuación w >= 1/raz,m a .dn, siendo me igual a la relación del limite de elasticidad del recubrimiento duro respecto al del acero inoxidable y en la que W satisface también la ecuación: Wsub3 >= ( w-2h) a2-d2n siendo h el grosor del recubrimiento en mim. 4. Una cuchilla de afeitar de acuerdo con la reivindicación 1, en la que la punta de la hoja o cuchilla está formada con facetas a una distancia de entre 40 y 100 mim desde el filo extremo,cuyas facetas convergen hacia el filo abarcando un ángulo del orden de 7º a 12º y preferentemente. de 9º a 11,5º. 5.
