And if you’ve ever done any re-work in an old house, you might find that many men cut a slit in the bathroom wall between the studs ... and guess where the used blades went ...
Yes, I’ve experienced the unexpected shower of rusty razor blades on our old house.
Your senses become amazingly accute all of a sudden when you realize what is happening. Luckily they’re so lightweight that I didn’t even get a scratch, but it sure is an interesting experience.
Our medicine cabinet had a slit in it. Always wondered what it was for until I did the remodelling on the other side of the wall.
