So today I discovered something that I'm sure many seasoned shavers have already discovered for themselves. I decided to take a blade which was nearing the end of itms ability to provide comfortable shaves but instead of tossing it, I placed it into another razor (which happened to be considerably more aggressive) and damn if it didn't give me a comfortable, perfect BBS shave. Is this a known method of keeping a blade's edge alive? Seems like something I'd read about here haha.
