I usually choose one razor/blade combo for the week. I could easily get ten or more shaves from one blade but I'd rather change blades before the shave deteriorates. And it's also easier for me to keep track of the number of shaves on the blade.Do you guys stay with the same blade all week or just the same kind of blade all week?
I go a bit longer with my SE blades, but I have enough of both DE and SE blades to last for several years so...
