Most states allow the possession and carrying of obsidian knives, given they don't exceed legal blade length restrictions. However, several states and local jurisdictions have specific regulations or bans on switchblades, gravity knives, or automatic knives. Since obsidian knives can sometimes resemble these restricted types, always check your local laws.

On a federal level, the Switchblade Act prohibits the interstate sale of "switchblade knives." However, this doesn't apply to obsidian knives, as they aren't considered switchblades. Always ensure your obsidian knife complies with federal standards by keeping an eye on the blade length and any locking mechanisms.

Moreover, federal law restricts underage possession, sale, and carriage of knives with a blade longer than 2.5 inches. Therefore, ensure that anyone under 18 adheres to these age restrictions while handling or owning an obsidian knife.
