What Is a Location-Restricted Knife in Texas?

A location-restricted knife in Texas is any knife with a blade longer than five and one-half inches.¹ Adults can own one and carry it almost anywhere in the state. The “location-restricted” label refers to a specific list of places where carrying it is a crime, including schools, courthouses, polling places, bars, airports past security, hospitals, places of worship, and amusement parks.²

Blade Length Is the Only Test

If the blade is longer than 5.5 inches, the knife is location-restricted. If it’s 5.5 inches or shorter, it isn’t, and no location-based carrying rules apply.¹ Shape and design don’t matter. A machete, a sword, a bowie knife, and a long chef’s knife are treated the same.

How to Measure

Texas law doesn’t prescribe a method, but the American Knife and Tool Institute publishes a protocol that’s widely referenced. You measure in a straight line from the tip of the blade to the front edge of the handle or hilt, using an ordinary ruler, and round down to the nearest one-eighth of an inch. If it’s unclear where the blade ends and the handle begins, use the measurement that gives the shorter length.

AKTI recommends that officers allow a one-eighth-inch tolerance, but they aren’t required to. If your knife sits right at the 5.5-inch line, assume it will be treated as location-restricted.

Where You Can’t Carry One

Texas Penal Code § 46.03 lists the places where carrying a location-restricted knife is an offense:²

Schools and universities: any campus, school-owned building, grounds hosting a school-sponsored activity, or school transportation vehicle, public or private.
Polling places on election day or during early voting.
Courthouses and offices used by a court, unless the court’s written rules allow it.
Racetracks.
Secured airport areas past the TSA screening checkpoint.
Bars and “51-percent” establishments, meaning businesses that earn 51 percent or more of their revenue from on-premises alcohol sales, as determined by the Texas Alcoholic Beverage Commission.
High school, collegiate, and professional sporting events, unless you’re a participant and the knife is part of the event.
Correctional facilities.
Civil commitment facilities.
Hospitals and nursing homes, unless you have written authorization.
Amusement parks.
Places of religious worship.

A separate provision bars carrying one within 1,000 feet of a designated execution site on the day a death sentence is scheduled, if you’ve been notified of the restriction. Most people will never encounter this one.²

Penalties Depend on the Location

For most of the prohibited locations, carrying a location-restricted knife is a Class C misdemeanor, punishable by a fine of up to $500 with no jail time.²³ That’s the same level as a traffic ticket.

Schools are the big exception. Bringing a location-restricted knife onto school premises, including a university campus or a school-sponsored event, is a third-degree felony.² A conviction carries two to ten years in prison and a fine of up to $10,000.⁴ The gap between a $500 ticket and a decade in prison is the single reason to double-check what’s in your bag before stepping onto any school property.

Rules for Minors

For anyone under 18, carrying a location-restricted knife is itself an offense unless one of three exceptions applies:⁵

The minor is on their own premises or premises under their control.
The minor is inside, or heading directly to, a motor vehicle or watercraft they own or control.
The minor is under the direct supervision of a parent or legal guardian.

Outside those situations, a minor carrying a location-restricted knife commits a Class C misdemeanor, with a fine of up to $500.⁵

The Vehicle Exception Doesn’t Help Adults

A common misconception is that you can keep a location-restricted knife locked in your car at a prohibited location. The vehicle rule in § 46.02 applies only to minors, letting someone under 18 have the knife in or on the way to a vehicle they own or control.⁵ For adults, that provision isn’t relevant, and the statute doesn’t cleanly answer whether a knife in a car parked at a hospital or school lot counts as being “on the premises.” The safe move is to leave it at home when you’re going somewhere on the prohibited list.

Cities and Counties Cannot Add Rules

Texas Local Government Code § 229.001 preempts local knife regulation. A municipality cannot pass or enforce rules governing the possession, carrying, transportation, or transfer of knives, and any ordinance that tries to is void.⁶ The narrow exception is a rule a municipality determines is necessary for public safety during an insurrection, riot, or natural disaster.

That means the list above is the whole list. A city can’t ban location-restricted knives from its parks, and a county can’t set a shorter blade-length threshold. State law is the only law on this question in Texas.
