I believe most people should carry a knife, yes, but most — at least around here — won't. For some unfathomable reason, they seem to be afraid of them. They're afraid of everything from something the size of a BK-9 right on down to the smallest SAK.
Why? I really don't know. Did they cut themselves as a child? Did their mommies teach them that knives are bad — something to be feared? Are these the exceptions to the claim the man is a tool using animal? I simply don't know.
People in less "advanced" societies learn to use knives as small children, and use them throughout their lives, without giving it a second thought, yet many here in what is — supposedly — the most advanced society on Earth, won't touch them.
Come to think about it, maybe those who fear even the smallest knife shouldn't carry them; fear and unfamiliarity cause fumbling, which causes accidents.
