Both my grampas had stroppers in their bathrooms, and they weren’t used for disposable blades. They used straight razors with a cup of hard shaving cream and a brush. Put a little water in the cup, brush up a lather, then pay attention.
For those of you who grew up later than I did, the strop was a strip of leather hanging by a ring adjacent to the barber’s chair. Barbershops still had them when I was a kid, and they were used to get rid of a used blade’s microscopic burl:
BTW, $2 in 1910 was about $50 in 2015 bucks.
Q1: Anyone remember the slots in bathroom walls for disposal of disposable Gillette blades into the wall cavities?
Q2: Did they ever fill up?

Got a slot like that in our downstairs bathroom medicine cabinet.

Nate– Get a magnet on a string and see how many you can fish out, then sell ’em on Ebay.
