So when you hear “I don’t like things in my pockets” your first assumption is that the speaker is unaware that hanging things off the side of their pockets is an option? Fine. For the pedantic: I don’t like having more than the bare minimum number of things in, on, or around my pockets.

Either way, still doesn’t change the fact that a very large number of people (myself included) have no use for a pocket knife in our daily lives.
