This is most likely a typical newbie thread but how many straight razors does one need? Initially, a couple so one can be used/practiced with while the other is re-honed if necessary. But straight razors can/should last a lifetime, if properly taken care of? I understand RAD (because I am also a pipe smoker afflicted with PAD). What is the purpose of the seven day razor sets? If I have a few well performing straights then I can shave and theoretically avoid RAD?
