Are Switchblades Legal? Automatic Knife Laws by State

Are switchblades legal? Yes to own in 44 states; 3 more add a condition, and D.C., Minnesota, New Mexico and Washington ban them.

Are switchblades legal is one question with two layers of answer: a federal law from 1958 that governs shipping and a short list of federal places, and a state law that decides whether you can own one, carry it, or carry it hidden. A switchblade, or automatic knife, is a folder whose blade opens on its own when you press a button or let gravity work, and out-the-front (OTF) knives count. Owning one is the easy part in most of the country; carrying it concealed is where states split. None of this is legal advice, and a city can add rules of its own, so match the knife to the statute in your row before it rides in your pocket.

Few knives have a reputation that walks in ahead of them like the switchblade (thank every greaser movie ever made). The button is not what gets people in trouble, though. The pocket is.

Are Switchblades Legal Under Federal Law?

Yes, to own, for most people. The Federal Switchblade Act, 15 U.S.C. §§ 1241 to 1245, defines a switchblade as any knife whose blade opens automatically by hand pressure on a button or other device in the handle, or by inertia, gravity, or both. It does two things. Section 1242 makes it a crime to bring one into, or ship or distribute one in, interstate commerce. Section 1243 bans making, selling or possessing one in a U.S. territory, in Indian country, or in the special maritime and territorial jurisdiction of the United States. Either one carries up to $2,000 and five years.

Section 1244 lists five exceptions: carriers, Armed Forces contracts, service members on duty, a one-armed person carrying a blade of three inches or less, and (added in 2009) any knife with a spring or detent biasing the blade closed that takes hand, wrist or arm effort to open. That last one is your assisted opener.

Switchblade Laws by State

Here is every state and D.C., read from the statute itself. “Open” and “concealed” mean carrying on your person. Where a row says automatics are not named, the state’s general weapons law is what applies.

Each row was read on October 18, 2026, from the official code site or, where marked, from Justia or public.law because the official site blocked us. “FOID” is the Illinois Firearm Owner’s Identification card. Counts in this article treat Massachusetts as legal to carry because of the 2024 court ruling. For more detail on any state, including blade-length rules for ordinary folders, use our knife laws by state map.

Where Automatic Knives Are Banned

Four places say no outright. D.C. Code § 22-4514 puts the switchblade knife on the same list as machine guns and blackjacks. Minnesota § 609.66 bars making, transferring or possessing a “switch blade knife opening automatically,” with up to 90 days in jail, or 364 in a school, park or public housing zone. New Mexico § 30-7-8 covers button, spring, gravity and centrifugal knives, and Washington RCW 9.41.250 makes owning a spring blade knife a gross misdemeanor.

Three more let you own one only on their terms. Illinois exempts anyone holding a current FOID card. New Jersey makes it a fourth-degree crime to have one “without any explainable lawful purpose.” New York allows one only “for use while hunting, trapping or fishing” by a person carrying a valid license. Outside that use, the exception does not cover you.

OTF Knife Legal? It Is a Switchblade

Out-the-front knives get no special pass. The federal definition covers any blade that opens by pressure on a button in the handle, and an OTF does exactly that, just straight out the nose instead of swinging out the side. California’s definition goes further and covers a blade released “by any type of mechanism whatsoever,” and New Mexico and Washington both name gravity and centrifugal openers. If your state restricts automatics, assume the OTF is caught too (our best automatic knife picks cover both styles side by side).

Assisted Openers Are Not Switchblades

An assisted opener needs you to start the blade with a thumb stud or flipper before a spring takes over, and that one detail moves it out of most switchblade laws. Federal law exempts it in 15 U.S.C. § 1244(5). Washington’s definition excludes a knife with “a bias toward closure” that needs “physical exertion” to open, and California excludes a one-hand opener with a detent that resists opening.

Remember, an assisted opener still counts as a knife. Blade-length caps and concealed-weapon rules apply to it like any folder, and our guide to choosing an EDC knife walks through the locks and openers.

What Changed in 2024, 2025 and 2026

Older guides go stale fast. These changes are confirmed in the statute or the court record:

• Hawaii, 2024: Act 21 of 2024 rewrote HRS § 134-52 so the only crimes are carrying one concealed or using one in another crime.
• Massachusetts, 2024: in Commonwealth v. Canjura, decided August 27, 2024, the Supreme Judicial Court held the carry ban in c. 269, § 10(b) violates the Second Amendment and invalidated it “only with respect to the prohibitions regarding switchblade knives.”
• Delaware, 2025: the switchblade dealing crime, 11 Del. C. § 1446, was repealed effective July 30, 2025. Concealed carry still needs a license.
• Vermont, 2025: Act 64 (S.109) cut switchblades from 13 V.S.A. § 4013 effective June 12, 2025, and ordered old convictions expunged.
• West Virginia, 2026: HB 4106, effective June 12, 2026, lets anyone 18 or older carry a concealed deadly weapon without a license. West Virginia’s “knife” definition names switchblades.

Concealed Carry Is Where People Get Caught

Having worked behind the counter for over 20 years, I get asked “is this legal?” about automatic knives more than any other knife, and the answer I give is the same every time: owning it is rarely the problem, hiding it is. Maryland, Oregon and Hawaii let you own one and forbid carrying it concealed. Delaware and North Dakota list switchblades as deadly or dangerous weapons, so concealed carry needs a license. Mississippi names the switchblade in its concealed-weapon list, and North Carolina’s pocket-knife exception excludes any knife opened by spring action.

So what does “concealed” mean? Mississippi’s code says a sheath or scabbard that is wholly or partly visible is not concealed. A clip above the pocket seam is not a visible sheath, and I would not bet a misdemeanor on it.

Blade length is the other trap door. California’s rule bites at 2 inches, Connecticut’s at 1.5 inches, and a Colorado concealed blade over 3.5 inches is a knife under its weapons law, automatic or not. Measure the blade before you argue about the button.

City Rules and Preemption

A state “yes” does not always cover the city you are standing in. Some states, such as Montana in MCA § 45-8-352, bar local governments from writing their own knife rules. Others leave the door open, and big cities walk through it. We keep separate pages for Chicago knife laws and New York City knife laws because both go further than their state.

Buying, Shipping and Traveling With One

The federal ban on shipping across state lines is aimed at the seller and the shipper, and the common-carrier exception covers the delivery company, not you. Driving across a state line with one in the truck means the law of every state on the route applies. Flying is simpler, and our TSA rules for EDC gear page covers what goes in checked bags.

Frequently Asked Questions

Which states are switchblades legal in?

Owning one is legal in 44 states with no license or condition. Illinois, New Jersey and New York allow it with a condition, and D.C., Minnesota, New Mexico and Washington ban it. Carry rules are narrower in 9 of the 44.

Can you legally buy a switchblade?

Yes, where your state allows ownership. The federal law that matters is the ban on introducing or shipping one in interstate commerce, which falls on the seller and shipper. Check your state row, then the seller’s shipping rules.

Can I carry a switchblade in North Carolina?

Openly, yes. G.S. 14-269 exempts from its concealed-weapon rule only an ordinary pocket knife that cannot be opened by “a throwing, explosive, or spring action,” so a concealed automatic falls outside that exception.

Is an assisted-opening knife a switchblade?

No, under federal law and in most states. 15 U.S.C. § 1244(5) exempts a knife with a bias toward closure that needs hand, wrist or arm effort to open, and Washington and California write similar language into their own definitions.

Are switchblades legal in Indian country?

Not for most people. 15 U.S.C. § 1243 bans making, selling or possessing one in Indian country, in U.S. territories and in places under special federal jurisdiction, whatever the surrounding state allows. Service members on duty and Armed Forces contracts are exempt.

So find your row, measure your blade, and carry it where people can see the clip if your state draws the line at concealment. The button is legal in more places than you think; the hiding spot is the part that writes tickets.
