Recently I’ve been reading the book Eifelhelm, which features a character named “Okham.” Another character facilitate with him says he’s met Okham’s successor and says “he used your razor.” It took me an embarrassing amount of time to realize that wasn’t meant literally. My first thought was that it was unsanitary, though the relevant part of the book is set in the 1300’s so I suppose that wasn’t a major concern.
