As of Feb. 25, 2026: Texas is broadly permissive about knives. The key compliance issue is whether a blade is over 5.5 inches (a location-restricted knife) and whether you’re entering one of the prohibited places listed in Texas Penal Code §46.03.

Quick Answer (TL;DR)

• 5.5 inches is the dividing line.
  A blade over 5.5 inches is a location-restricted knife (LRK) under Texas law.
• LRKs are legal in most places—but banned in specific locations.
  The biggest risks are schools, courts, polling places, secured airport areas, 51% alcohol businesses (bars), sporting events, certain medical facilities without written authorization, and amusement parks, among others.
• Measure correctly.
  Don’t rely on “sharpened edge only.” Texas case law (McMurrough) supports a tip-to-hilt style measurement approach rather than “edge length.”

What Counts as a “Knife” in Texas?

Texas defines “knife” broadly as a bladed hand instrument capable of causing serious bodily injury or death by cutting or stabbing.

Practical takeaway: Most common folding knives, fixed blades, and multi-tools are “knives” under the Penal Code. The legal risk usually comes from blade length and where you carry.

What Is a “Location-Restricted Knife” (LRK)?

A location-restricted knife is a knife with a blade over five and one-half inches.

If your blade is 5.5 inches or less, it’s treated as a standard “knife” for most carry purposes. Once you go over 5.5 inches, you’re in LRK territory—and the place-based prohibitions matter.

Where Are Location-Restricted Knives Prohibited in Texas? (Penal Code §46.03)

If your blade is over 5.5 inches, you should treat this section as your compliance checklist. Texas Penal Code §46.03 lists places where weapons (including LRKs) are prohibited.

Prohibited Places for LRKs (Plain-English Checklist)

Do not carry an LRK into:

• Schools and postsecondary educational institutions (including certain school activities and transportation)
• Polling places (on election day or during early voting)
• Courts or offices used by the court
• Racetracks
• Secured areas of airports (beyond screening)
• 51% alcohol businesses (“bars”)
• Sporting events and interscholastic events (subject to limited exceptions)
• Correctional facilities
• Certain civil commitment facilities
• Hospitals and nursing facilities without written authorization
• Mental hospitals without written authorization
• Amusement parks
• Rooms where certain open meetings of governmental bodies are held (with required notice)

Best practice: If you carry an LRK, plan your day around these locations. The most common “accidental” violations happen with bars, courthouses, airports, and events.

The “51% Rule” (Bars) Explained

Texas prohibits carrying an LRK on the premises of a business that earns 51% or more of its income from the sale/service of alcohol for on-premises consumption (commonly “bars”).

Real-world tip: If you’re unsure whether a place is a “51%” premises, treat it as prohibited for LRKs and leave the large blade secured elsewhere.

How to Measure Blade Length Correctly (McMurrough)

Measurement disputes are common. In McMurrough v. State (Texas Court of Appeals, 1999), the case record reflects that enforcement and courts focus on overall blade length rather than “sharpened edge only.”

Safe measurement method

• Measure in a straight line from the tip to the forward-most part of the handle/hilt.
• If your knife is marketed at 5.5″, but design features extend the blade base, you can still measure over the threshold.

Compliance tip: If you want to avoid LRK restrictions entirely, choose knives with clearly shorter blades (e.g., ~4.5–5.0″) to account for measurement variance.

Minors and Knife Carry: High Risk, Fact-Specific

Knife rules for minors (especially with blades over 5.5 inches) are more restrictive and fact-specific. If your site targets families, scouting groups, or youth outdoor programs, treat this as a separate topic and cite the exact statutory provisions you’re relying on.

Editorial note for WordPress: Consider making a dedicated post titled “Texas Knife Laws for Minors (2026)” and internally linking to it from this guide. That helps topical authority and reduces misinterpretation risk on a single page.

State Preemption: Why City Knife Bans Don’t Control

Texas has state-level preemption limiting local regulation of knives, which helped eliminate the old patchwork of city-specific rules. For readers, that means Texas Penal Code rules generally control statewide.

(If you want, I can write a short “Preemption explained” box that quotes and cites the specific Local Government Code section once you confirm you want that in this post.)

89th Legislature Update (2025): What Happened to HB 2239?

HB 2239 (89R, 2025) proposed changes related to locations where certain knives are prohibited. The official Texas Legislature Online history shows it was referred to the Senate Criminal Justice Committee on May 12, 2025, with no enactment reflected on that bill history record as of this review date.

Bottom line for 2026 readers: Don’t assume HB 2239 changed current rules unless you confirm a later enactment record.
