Switchblade Versus Pocket Knife?

A switch blade is just that, a knife with a spring or piston activated blade that is ejected when a button is pushed and is almost certainly illegal in Commiefornia. Pretty much everything is if you want to defend yourself. Knife laws also may not have state preemption saying that state law trumps all city and county laws so each city and county may have different laws and regulations whats legal in San Diego might be illegal in LA. The best thing to do is call your police department non emergency number and ask the police where you live, work, and travel to a lot what their specific knife laws are. Or move to a free-er state than California where you can walk down the street with a Commando knife if you so choose.
