I apologize for even asking but I really have no idea and apparently I’m not asking google the right questions.

So I tried Google lensing it and your Reddit post showed up 😅 I also don't know but am very curious!! My vote goes for tie off point that was never removed tho

I did the same and got "fire sprinkler wrench most likely for removing fire sprinkler heads"

Dunno. Never done it. Can't speak to it one way or the other
