Texas knife law underwent a dramatic transformation on September 1, 2017, when House Bill 1935 took effect. Before this reform, Texas maintained strict restrictions on knife types, banning so-called “illegal knives” like Bowie knives, daggers, switchblades, and blades longer than 5.5 inches in most public places.
The new law eliminated the “illegal knife” category entirely, making it legal to own and carry virtually any type of knife regardless of size or design.
The 5.5-Inch Blade Rule
Today, Texas law centers on one critical measurement: 5.5 inches. Adults and juveniles can carry knives with blades under 5.5 inches anywhere in the state without restriction. For pocket knives specifically—which typically have blades between 2.5 and 4 inches—this means unrestricted carry throughout Texas.
Knives with blades 5.5 inches or longer become “location-restricted knives.” While still legal to own and carry, they cannot be taken into certain prohibited locations:
Concealed vs. Open Carry
Texas has no distinction between concealed and open carry for knives. You may carry pocket knives openly or concealed however you prefer. There is also no limit on the number of knives you can carry.
Minors and Special Restrictions
Minors under 18 face additional limitations:
- Cannot purchase location-restricted knives (blades ≥5.5″)
- Cannot carry blades over 5.5 inches unless on their property, in a private vehicle, or accompanied by a parent/guardian
- Parents need written permission to sell location-restricted knives to minors
Penalties for Violations
Violating Texas knife laws carries serious consequences:
- Class C misdemeanor: Up to $500 fine for carrying location-restricted knives to prohibited areas like amusement parks
- Class A misdemeanor: Up to 1 year jail and $4,000 fine for serious violations
- Third-degree felony: Carrying location-restricted knives into schools
Important Exceptions
Two items remain illegal to possess in Texas:
- Knives incorporating “knuckles” as part of the handle (e.g., WWI trench knives)
- Tomahawks (classified as “clubs”)
State Preemption
Texas has state preemption, meaning local cities cannot enact stricter knife ordinances than state law. What’s legal statewide applies everywhere in Texas.
