never really paid much attention. probably 3 or 4 shaves. if they don't feel right, i toss them and start fresh.
I actually get away with about 15-20 shaves with 1 blade! My hair is so thin that I change my blade about once per month. After that, it don't feel right, i toss them and start fresh.
man.... kalboarnie.... one blade=one month. u gotta luv that!!! talk 'bout saving some $$$!!!
