i used to never shave my face ( except if i had a goatee) , just use hair trimmers with no guard .. but i used to shave my head with them once-twice a month , id get about one head shave per fusion blade , and 2-3 face shaves ... really i could care less if i ever shaved before not cause i hated shaving , just hated a clean face ... now with the straights i shave just to shave , i still hate a shaved face but the fun of thee straight razor far out weighs not liking a clean mug !!
