I'm not a lawyer and I'm not a cop, but I have worked in law enforcement. It is a common fallacy that any item such as a screwdriver or a hammer or a baseball bat or a utility knife isn't a 'weapon' when carried. It depends upon context. If you're carrying a baseball bat and you're on your way to a baseball game, no issues. If you're carrying a baseball bat down a dark alley in the middle of the night while shouting that you're going to bash someone's head in, then it's a weapon. You can claim "No, it's not a weapon, it's only a baseball bat" all you like, you are headed for the crossbar hotel.
Same with anything a person might carry to defend themselves. If it's for self-defense, it's a weapon. There's no 'ah ha, fooled you, it's legal' to it. Ask any cop or attorney.
No, box cutters won't ever be banned. Neither will kitchen knives. Tuck either one in your pocket and tell the cop that it's for self-defense and now it's a weapon and depending on where you are, it may be illegal. Again, don't believe me; ask a cop or lawyer.
