Knives are a top choice for hunting, self-defense, and sport weapons, but it’s essential to know your state knife laws. Switchblades have often sat in the gray area of legality, and the specific details of the law can differ from state to state.
A switchblade is a kind of knife that has a folding or sliding blade that is stowed in the handle. A switchblade is usually spring-loaded and opens automatically when a button or switch on the handle is pressed.
