I was reading a completely unrelated forum, and found this quote:

Dad was handy with the razor strop. I used to PRAY he’d start to use a safety razor. No such luck.

Aw. I imagine a pair of sisters pooling their pocket money to buy their father a top-of-the-range safety razor for his birthday.

He receives is gratefully.

The razor strop migrates from the bathroom to a prominent hook on the wall, where from now on it’s used only for one, very painful purpose.
