Law-abiding residents of Hawaii want to own folding pocket-knives with split handles, also sometimes known as butterfly knives. But this type of knife is banned in Hawaii. This prohibition violates the Second Amendment-protected right to keep and bear arms, since the word “arms” applies to knives and other bladed weapons.

Even in an emergency, constitutionally protected rights must be defended. New Mexico’s governor shut down the state’s firearms retailers as part of her emergency shut down orders designed to stop the spread of COVID 19. But her order illegally deprives citizens of their Second Amendment protected rights. MSLF filed a lawsuit, on behalf of multiple individuals, firearm retailers, and a litany of Second Amendment advocacy organization, to vindicate those rights.
