I got this hundred-year-old razor some time ago and still don't know what to do with it. The only thing I know for sure is that I will scale it in a horn, hone it, and shave with it. But before that I need to choose what to do with the blade. On one hand, there's a beautiful engraving with the "Royal" and the Coat of The Most Noble Order of the Garter, and on the other, there's this pitting. I don't know anything about the razor belonging to the royal family or their barbers, but I want to save the engraving as much as possible. What would you advise to clean the razor and whether it should be cleaned at all?
