Due to work and keeping a "professional appearance", I have to shave Monday to Friday. Weekends I try to skip it when possible and let my skin rest. But if I have something special going on like a family gathering, wedding, funeral, etc. I'll shave with my straight razor on Saturdays and Sundays. If I had my way, I'd only shave every second day though, at least, because it feels better to shave after a couple days of growth. Not as much irritation and the skin feels smoother.
