to restore or not to restore
I'm torn on that question, I guess it depends on the razor.... but sometimes I let my foggy old brain think about the guy who bought and paid for a new razor 100-150 years ago. The razor likely cost him a week's pay and was a prized possession. Maybe that razor belonged to a barber and was a valued tool for making a living. Maybe it belonged to a soldier and helped keep a dozen or more friends looking decent. At any rate, there's a good chance that it was kept clean and polished then, men of that day knew how to maintain their belongings.
tough crap for that guy on the Roadshow, that's just the way it goes.
