Each state has its own laws regarding the possession of weapons, including guns and knives. Knife Up made this infographic to show what states’ rules are regarding pocket knife possession. Titled “State Knife Possession Laws,” it features three maps of the U.S. Each map has different data. The first shows in which states ballistic knives are illegal. The second shows where switchblades are illegal. The third shows where it is illegal to carry concealed pocket knives. The third map also shows details regarding how big the knife must be to be considered illegal in each of the states.
