We are in receipt of your e-mail inquiring about the legality of the Balisong style knife. The Colorado statutes do not detail specific types or styles of knives when determining whether such a weapon is considered to be legal. The statutes, as you note, describe the characteristics which make a weapon subject to prohibition.
The actual determination whether any edged weapon is considered to be an illegal weapon, as defined by 18-12-102, is a question of fact. While, ultimately, questions of fact are decided by jurors, our belief is that a so-called Balisong knife is, indeed, a gravity knife, the possession of which is prohibited by Colorado law. I hope we have been of some assistance.
