Louisiana generally permits adults to own common folding knives, fixed blades, and automatic knives. The state repealed its former automatic-knife provision, and current law focuses mainly on intentional concealment of a dangerous weapon, prohibited places, conduct, and age or legal-status restrictions. [1]
Since July 4, 2024, Louisiana Revised Statutes § 14:95(M) states that the general concealed-dangerous-weapon provision in § 14:95(A)(1)(a) does not apply to a person age 18 or older who is not prohibited from possessing a firearm under state or federal law. That wording is broader than a handgun-only exception, but prohibited places and other offenses still apply. [1]
What knives may adults own in Louisiana?
Louisiana does not impose a general state ban on adult ownership of ordinary pocketknives, fixed blades, automatic knives, OTF knives, or balisongs. The former automatic-knife paragraph in § 14:95 is marked repealed by Acts 2018, No. 341. [1]
Ownership does not authorize threatening display, criminal use, possession in a prohibited place, or violation of school, employment, and private-property rules.
May adults carry knives openly?
Louisiana does not impose one general statewide blade-length limit for open carry of every lawful knife. However, carrying or displaying a knife in a threatening way, using it during an offense, or entering a prohibited location can lead to criminal liability under other provisions.
Keep the knife closed or sheathed when not in use and avoid any display that another person could reasonably understand as a threat.
May adults carry knives concealed?
Section 14:95(A)(1)(a) defines illegal carrying of weapons to include intentional concealment of a firearm or other instrument customarily used or intended for probable use as a dangerous weapon. Section 14:95(M), effective July 4, 2024, says that this provision does not apply to a person age 18 or older who is not prohibited from possessing a firearm under state or federal law. [1]
Reading those provisions together, the adult exception appears to cover concealed knives that would otherwise be treated as dangerous weapons under A(1)(a), not only handguns. This is a direct reading of the statutory text, not a promise that every knife-related situation is lawful. Persons under 18, prohibited possessors, restricted places, threatening conduct, and other offenses require separate analysis.
Are automatic knives prohibited?
No current Louisiana statute creates the former blanket automatic-knife prohibition in § 14:95. The statute identifies that paragraph as repealed in 2018. [1]
Federal commerce and shipping rules can still apply to switchblades. Automatic opening also does not override prohibited-place rules or transform threatening use into lawful conduct.
Where are dangerous weapons prohibited?
Section 14:95 separately addresses possession or use of dangerous weapons on school campuses during regular school hours and on school buses. It also prohibits dangerous weapons at specified law-enforcement offices, detention facilities, prisons or jails, courthouses or courtrooms, and the state capitol, subject to statutory exceptions. [1]
The precise definitions, boundaries, permissions, and exceptions matter. Do not rely on a short summary when entering a secure facility.
What rules apply to students and schools?
Louisiana’s student-discipline statute states that students generally may not carry or possess a knife of any blade length. It distinguishes knives below 2.5 inches from those with blades of 2.5 inches or longer for suspension and expulsion procedures and contains exceptions for school classes or approved activities. [2]
Practical rule: students should not bring any knife to school, a school bus, or a school activity unless the school has expressly approved it for a legitimate program.
Can Louisiana cities adopt stricter knife laws?
Louisiana expanded its weapons-preemption statute effective August 1, 2024. Section 40:1796 now generally bars political subdivisions from adopting or enforcing rules more restrictive than state law concerning knives and edged weapons, including their manufacture, sale, purchase, possession, carrying, storage, ownership, transfer, and transportation. The statute includes exceptions. [3]
This substantially limits local knife regulation, but it does not erase state prohibited-place rules, private-property rights, generally applicable criminal law, or the listed statutory exceptions.
What vehicle, travel, and private-property rules matter?
Keep any knife closed or sheathed and secured against movement during transport. A vehicle does not override restrictions at schools, courthouses, detention facilities, law-enforcement buildings, the state capitol, or private property.
Businesses, employers, event operators, and property owners may prohibit knives. The Transportation Security Administration prohibits knives in carry-on baggage except for plastic or round-bladed butter knives. Checked-baggage and airline requirements still apply. [4]
What should you verify before carrying?
- Whether the carrier is at least 18 and is not prohibited from possessing a firearm under state or federal law.
- Whether the knife may be treated as an instrument customarily used or intended for probable use as a dangerous weapon.
- Whether the destination is a school, school bus, courthouse, jail, law-enforcement building, state capitol, or another secure location.
- Whether the property owner, employer, or venue prohibits knives.
- Whether federal law or another state’s law applies to the trip or transaction.
Conclusion
Louisiana generally permits common knives and repealed its former automatic-knife prohibition. The 2024 adult exception significantly changed the general concealed-dangerous-weapon rule for eligible people age 18 or older, while schools, secure government locations, conduct-based offenses, federal rules, and private-property restrictions remain important. Louisiana also now broadly preempts more restrictive local knife regulation.
