> Some knives (switchblades and gravity knives especially) are illegal in most places.
I think it's usually about carrying them in public outside your house. Likely not as illegal to have them at home.
Gravity knives are scary in that the police have occasionally argued that certain common pocketknives (e.g. Leatherman) can be used as a gravity knife and arrest people (usually minorities of the wrong color). I once was going on a road trip across multiple states and had to research the laws of each state because I was carrying a Leatherman.
