Chances are you've come across a photo of someone's alleged everyday carry and thought, "why does this guy (or gal) carry so many knives?"
It happens to me frequently. I'll come across someone who apparently carries three, four, or more knives on their person.
That simply strikes me as absurd. I can't fathom a reason to EDC more than two knives; it seems like an under-thought extension of "two is one, one is none."
The EDC discipline should be bounded by utility and utility is bounded by diminishing return. It's simple: carry more knives, lose utility with each additional knife.
