The Second Amendment guarantees the right to keep and bear “Arms”–not solely “firearms.” While firearms have always been the paradigmatic Second Amendment arm, there are many other types of arms which are protected by the Second Amendment. By far the most common of the other arms are knives.
Now at the printer is the first detailed scholarly analysis of Knives and the Second Amendment. 47 University of Michigan Journal of Law Reform, vol. 47, pages 167-215 (Fall 2013). The article is co-authored by Clayton Cramer, Joseph Olson, and me. We argue that:
- 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.
- There is no knife that is more dangerous than a modern handgun; to the contrary, knives are much less dangerous. Therefore, restrictions on carrying handguns set the upper limit for restrictions on carrying knives.

For example, bans of knives that open in a convenient way (e.g., switchblades, gravity knives, and butterfly knives) are unconstitutional.

The article provides an explanation of various types of knives, of criminological evidence regarding knives, and of the 19th century panic and case law about Bowie Knives and Arkansas Toothpicks. We then apply the Second Amendment to modern knife laws. We cover the utility of knives for personal self-defense and for militia use, and the constitutional significance of technological changes in knives since 1791. Finally, the article considers some modern prosecutions, statutes, and cases from Washington, Oregon, Indiana, New York, and D.C. We conclude that even under the weakest relevant standard (intermediate […]
