Yes, you can carry a pocket knife in Texas. If you are 18 or older, state law lets you carry a pocket knife of any blade length, openly or concealed, in most places. The one line that matters is 5.5 inches: at or below that, a knife goes almost anywhere; above it, a specific list of locations is off-limits.
General Rules for Adults
A 2017 overhaul eliminated the old “illegal knives” category, which had banned daggers, stilettos, Bowie knives, swords, and any blade longer than 5.5 inches.1American Knife and Tool Institute. Texas Knife Laws The current framework drops every restriction based on blade style, opening mechanism, or edge type. Single-edged, double-edged, spring-assisted, fixed blade, switchblade, automatic, gravity knife—Texas treats them the same. The only questions are blade length and location.
Open carry and concealed carry are both legal. There is no cap on how many knives you can have on you at once. For a standard pocket knife with a blade of 5.5 inches or shorter, state law places essentially no limits on where you take it, though private property owners can still set their own rules on their premises.
The 5.5-Inch Line
Texas Penal Code Section 46.01 defines a “location-restricted knife” as any knife with a blade over 5.5 inches.2State of Texas. Texas Penal Code 46.01 – Definitions A blade measuring exactly 5.5 inches is not location-restricted. Brand, style, handle, and locking mechanism don’t factor in. Only length.
Blade length is measured in a straight line from the tip to the forward-most point where the handle begins. The American Knife and Tool Institute recommends using a standard ruler, measuring in one-eighth-inch increments, and rounding down when a measurement falls between increments.3American Knife and Tool Institute. AKTI Protocol for Measuring Knife Blade Length If your knife is anywhere near the line, measure it before you carry it.
Where a Longer Blade Cannot Go
Texas Penal Code Section 46.03 lists the places where carrying a knife with a blade over 5.5 inches is a criminal offense:4State of Texas. Texas Penal Code 46.03 – Places Weapons Prohibited
- Any public or private K-12 school or postsecondary institution, including school-sponsored activity grounds and school buses
- Polling places, on election day or during early voting
- Government court buildings and offices used by the court
- Racetracks
- Secured airport areas past federal screening
- Correctional and civil commitment facilities
- Hospitals and nursing facilities, unless the administration gives written authorization
- Mental health facilities, unless the administration gives written authorization
- Bars and similar businesses that get 51 percent or more of their revenue from on-premises alcohol sales and post the required “51%” notice
- High school, collegiate, or professional sporting events and interscholastic competitions
- Amusement parks
- The room where an open meeting of a governmental body is being held
- Within 1,000 feet of a designated place of execution on the day a death sentence is scheduled, if you received notice
A knife with a blade of 5.5 inches or less is not covered by these location restrictions under state law.
Penalties
Carrying a location-restricted knife in one of those places is generally a Class C misdemeanor, punishable by a fine of up to $500 and no jail time.5State of Texas. Texas Penal Code 12.23 – Class C Misdemeanor The penalty jumps sharply on school grounds. Carrying a location-restricted knife at a school or educational institution can be charged as a third-degree felony, punishable by 2 to 10 years in prison and a fine of up to $10,000.6State of Texas. Texas Penal Code 12.34 – Third Degree Felony
Exceptions
Texas Penal Code Section 46.15 carves out a few situations where the location restrictions do not apply. You are exempt if you are traveling. The statute does not define the term, but Texas courts have historically read it as journeying beyond your daily routine. You are also exempt while actively hunting, fishing, or engaged in another lawful sporting activity, or heading between the activity site and your home or vehicle.7State of Texas. Texas Penal Code 46.15 – Nonapplicability Location-restricted knives used in a historical demonstration or a ceremony where the knife is significant to the performance are also exempt.
If You Are Under 18
Minors face tighter rules. A person under 18 commits an offense by carrying a location-restricted knife in public unless one of three exceptions applies: the minor is on property they own or control, inside or heading directly to a vehicle or watercraft they own or control, or under the direct supervision of a parent or legal guardian.8State of Texas. Texas Penal Code 46.02 – Unlawful Carrying Weapons Violating this rule is a Class C misdemeanor for the minor.
Selling, giving, or otherwise providing a location-restricted knife to anyone under 18 is a Class A misdemeanor for the adult, punishable by up to one year in jail and a fine of up to $4,000.9State of Texas. Texas Penal Code 46.06 – Unlawful Transfer of Certain Weapons10State of Texas. Texas Penal Code 12.21 – Class A Misdemeanor There is an affirmative defense if the minor’s parent or legal guardian gave written permission for a sale, or effective consent for any other type of transfer.
These rules cover location-restricted blades only. A minor can carry an ordinary pocket knife with a blade of 5.5 inches or less without triggering them.
Federal Property and Airports
State law stops at the boundary of federal property. Federal buildings, courthouses, post offices, and military installations follow federal rules that are significantly stricter than Texas law. Under 18 U.S.C. § 930, any knife with a blade of 2.5 inches or longer qualifies as a “dangerous weapon” that cannot be brought into a federal facility. Only a pocket knife with a blade under 2.5 inches is exempt.11Office of the Law Revision Counsel. 18 USC 930 – Possession of Firearms and Dangerous Weapons in Federal Facilities Violating this law can result in up to one year in prison for general federal facilities and up to two years for federal courthouses.
Military installations layer their own policies on top of federal law. Regulations governing some installations treat any knife with a blade over 3 inches as a weapon requiring visible carry in a sheath, with concealed carry prohibited.12eCFR. 32 CFR 552.129 – Requirements for Carrying and Use Individual base commanders can impose additional restrictions.
At the airport, TSA prohibits all knives in carry-on luggage and on your person at security checkpoints. Knives are allowed in checked bags. If you arrive at a checkpoint and realize you still have a knife, you can return to your car, take it back to the airline counter to check it, mail it to yourself, or surrender it.13American Knife and Tool Institute. Traveling With a Knife
Local Ordinances
No Texas city or county can pass a stricter knife rule than the state provides. Under Texas Local Government Code Section 229.001, municipalities cannot regulate the possession, carrying, transportation, or sale of knives, and any local ordinance attempting to do so is void.14State of Texas. Texas Local Government Code 229.001 Houston, Dallas, Austin, and San Antonio all follow the same rules described above. Private property owners can still restrict knives on their premises, but no local government can add criminal penalties beyond what the state penal code already covers.
