Question: is a butterfly knife illegal in new york?
Answer: In New York, the balisong has been determined not to be a gravity knife, and therefore not prohibited under the Penal Law [see: People v. Zuniga, 303 A.D.2d 773 (2nd Dept. 2003)] However, the law prohibiting gravity knives was found to be unconstitutional and their possession was decriminalized in 2019.
