Automatic Knife & OTF Knife Laws
An OTF (Out-the-Front) knife is a type of automatic knife in which the blade deploys through the front of the handle. Automatic knives may also be referred to as auto-open knives, switchblades, or switch knives in laws and other resources.
Automatic knives are currently legal in most U.S. states, but that doesn't mean the rules are the same everywhere. States may impose restrictions involving blade length, possession, carry, concealment, sale, or location, so it's important to check the specific laws that apply to you.

State Knife Laws
This content on this page is provided for general informational purposes only and is not legal advice. Knife laws can change and may vary by state and local jurisdiction. Always verify current laws applicable to your location and circumstances before purchasing, possessing, carrying, or traveling with a knife.
Where can I find current knife laws for my state?
The American Knife & Tool Institute (AKTI) maintains state-by-state knife-law summaries with legal references and updated information. Because laws change, AKTI recommends using its summaries as a starting point and verifying applicable state and local laws when necessary. Search knife laws by state on AKTI.
Can I carry an OTF knife if it's legal to own in my state?
Not necessarily. A state may allow possession of an automatic knife while placing separate restrictions on carry, concealment, blade length, or certain locations. Local ordinances may also apply depending on the state.
Can knife laws vary within the same state?
Yes. In states without knife-law preemption, cities, counties, or other local jurisdictions may impose restrictions beyond state law. States with preemption generally prevent local governments from enacting knife restrictions more restrictive than state law, although the specifics vary.
Are OTF knives legal?
OTF knives are a type of automatic knife. Automatic knives are legal in most states, but restrictions can vary by state and may involve blade length, carry, possession, sale, or other factors. Check the current laws for your state before purchasing or carrying an OTF knife.
Is an OTF knife the same as a switchblade?
OTF knives fall within the broader category of automatic knives. Laws may use terms such as automatic knife, switchblade, auto-open knife, or switch knife, so it's important to understand how the law in your jurisdiction defines and regulates the knife you're carrying.
