Texas Knife Laws

While some states have laws that regulate the use of knives by classifying them according to the opening mechanism or style and shape of their blade, Texas removed its old, similar knife laws. Instead of the complicated legislation that assigned different knife types to particular knives, Texas opted for a more straightforward classification system for bladed weapons.

As of 2017, Texas knife laws classify knives based solely on the knife blade’s length. This system for knife classification already simplifies the law, making it easier to understand and regulate. Furthermore, the state of Texas continues to disentangle the complexities of its former laws by only concerning itself with two “types” of knives. 

What Types of Knives Are Legal To Carry in Texas?

According to statute § 46.01, a “knife” may be “any bladed hand instrument that is capable of inflicting serious bodily injury or death by cutting or stabbing a person with the instrument.” The two types of knives classified by current Texas state law include “location restricted knife” and “knife.” 

“Location Restricted Knife”

Texas knife laws deem any bladed hand instrument with a blade longer than 5.5” a “location restricted knife” under Chapter 46 of the Penal Code. While these knives are legal to own and carry in Texas, as the name suggests, there are restrictions on locations where people can have these knives. 

Since the 1999 case of McMurrough v. The State of Texas, Chapter 46 identifies the blade of a knife as the “flat-edged part of the knife, which includes the sharpened part of the instrument and any remaining flat-edged part up to, but not including, the handle.” 

In addition to location restrictions, Chapter 46 of the Penal Code also indicates that knives with blades over 5.5” in length cannot be in possession of any person under the age of 18. Exceptions include wielding the knife on the person’s own property or property under that person’s control, if the knife is being used for legal hunting or fishing purposes, or if the person is under the direct supervision of their parent or legal guardian.


Chapter 46 deems any other bladed hand instrument with a blade less than or equal to 5.5” in length as simply a “knife.” There are no restrictions for any person, including persons under the age of 18, to possess a knife with a blade less than or equal to 5.5” in length. 

What Types of Knives Are Illegal To Carry in Texas?

Even though most knives are legal to carry in Texas, there are still a few exceptions to the law for other bladed instruments. While some aren’t technically knives, be cautious if considering ownership of trench knives with knuckle dusters, brass knuckles, tomahawks, clubs, or axes.

Legal Defenses for Knife Charges

Those with charges for knife possession in Texas have a few options for defense in their case. The most common defenses for knife charges include upholding that the knife was not outside of regulation, that the knife was unknowingly in the person’s possession, or that police found the knife during an illegal search or as a result of police misconduct.
