A long while ago, I was told that one should never allow moonlight to fall on the edge of a razor, as it would dull more quickly. Being a simple country lad, I believed it at the time, though I now recognize that advice for what it is - a heap of steaming, without foundation in experience or science.
Do any of you gentlemen out there have any other examples of the razor myths which circulated as facts amongst the old-timers?
