Yes, you may own and carry one but there are important rules about where you carry it, how old you must be, and what counts as a “location-restricted knife.” Failing to pay attention to those can lead to legal trouble.
How Texas Law Treats Switchblades and Other Knives
Under Texas law:
- A switchblade (automatic-opening knife) is not banned. Texas removed prior prohibitions on automatic knives.
- The major legal distinction now is blade length: Texas defines a “location-restricted knife” as any knife with a blade over 5½ inches.
- For knives with blades of 5½ inches or less, they are generally treated like any other knife in Texas law.
- If a knife is a location-restricted knife (blade over 5½ inches), you may carry it, but the law places restrictions on where it can be carried.
What You Can Do If You Own or Carry a Switchblade in Texas
- You may own, buy, manufacture, repair, or sell an automatic knife (switchblade) in Texas, unless local law or specific location provisions prohibit it.
- You may carry a switchblade — but if the blade is longer than 5½ inches, you must be careful about location restrictions.
- For knives with blades under 5½ inches (including many switchblades), your carry is much less legally restricted.
- The knife laws are pre-empted at the state level: local governments generally can’t impose stricter rules than state law allows (though they can restrict particular places such as schools or razor-thin categories).
What Are the “Location-Restricted Knife” Rules?
When dealing with blades over 5½ inches, Texas law lays out specific places where carry is prohibited. These include:
- On the premises of a school or educational institution, including buildings or grounds of a school-sponsored event.
- On the premises of a polling place during an election.
- In a courtroom or government office used by the court.
- Within a secure area of an airport.
- On premises of a business that holds a liquor license and derives 51 % or more of its income from alcohol sold for on-premises consumption.
- Correctional facilities, amusement parks, other defined “sensitive locations.”
If you carry a knife that is location-restricted in one of those places, you could be subject to Class C misdemeanor or more serious charges depending on the situation.
Why Texas Law Changed and What It Means
- In 2013, Texas passed a law (House Bill 1862) effective September 1 that eliminated the ban on switchblades and automatic knives.
- Later in 2017, with House Bill 1935, Texas removed the category of “illegal knives,” broadening rights to carry various blades — while still defining location-restricted knives by blade length
- The idea: Texas moved from regulating knives by their mechanism (automatic, switchblade) to regulating them by their size and location of carry. That gives knife owners more freedom — but still holds certain places off-limits.
What You Should Make Sure To Know
- As someone who wants to stay on the right side of the law in Texas in 2025:
- If you have an automatic knife (switchblade), check the blade length. If it’s under or at 5½ inches you are in a safer legal zone; if it’s over 5½ inches, you become subject to location restrictions.
- Even if the blade is short, be aware of restricted locations(schools, courtrooms, polling places, etc.). Carrying into a forbidden place can trigger charges.
- Age matters: Minors (under 18) cannot carry “location-restricted knives” (those over 5½ inches) except under limited exceptions.
- Where you carry matters: The laws focus on where you are carrying, often more than just the knife itself.
- Local ordinances: Because Texas pre-empts local laws, the state law sets the floor, but you should still check your city/county for added rules or signage that restrict knives in certain facilities.
Final Take
Yes — in Texas you can legally own and carry a switchblade. The laws allow automatic knives. But don’t think it’s a free pass. Blade length and location matter. A switchblade over 5½ inches becomes “location-restricted” and you need to watch where you carry it. If you carry a switchblade through a school, government building, polling place, or liquor-licensed bar that depends mostly on alcohol, you could be in trouble. So if you want to stay safe, check both your knife’s size and your location before you carry.
