How long does it take for a knife to become blunt
It is impossible to say how often you have to replace a cassette because a number of factors influence how long the blade lasts. Much depends on the way you handle the blades after shaving. When you need a new blade depends on how often you shave, the surface you have to remove the hair from, the type of hair, thickness and length and the number of shaving movements.
However, the strength/hardness of the hair is not the reason that razor blades should be replaced quickly and on average after every 20 shaves. Razor blades become dull mainly because hairs, soap/foam, lime, and skin cells remain on the razor. The small residual particles cause corrosion on the blades, making them blunt. See also: Why razor blades become blunt. The more often you shave, the more often the blades get wet and the more skin/soap residues remain on the blades.
