Knives and the Second Amendment

Professors David B. Kopel, Clayton E. Cramer, and Joseph Olson have posted on SSRN the first scholarly analysis of knives and the Second Amendment:

Abstract:  This Article is the first scholarly analysis of knives and the Second Amendment. Knives are clearly among the “arms” which are protected by the Second Amendment. Under the Supreme Court’s standard in District of Columbia v. Heller, knives are Second Amendment “arms” because they are “typically possessed by law-abiding citizens for lawful purposes,” including self-defense.    Bans of knives which open in a convenient way (bans on switchblades, gravity knives, and butterfly knives) are unconstitutional. Likewise unconstitutional are bans on folding knives which, after being opened, have a safety lock to prevent inadvertent closure.    Prohibitions on the carrying of knives in general, or of particular knives, are unconstitutional. There is no knife which is more dangerous than a modern handgun; to the contrary, knives are much less dangerous. Therefore, restrictions on the carrying of handguns set the upper limit for restrictions on knife carrying.
