Missouri is known for its lenient knife laws, allowing individuals significant freedom to own and carry various types of knives. However, there are important nuances regarding concealed carry, restricted locations, and federal regulations. Here’s a comprehensive guide to understanding your knife rights in Missouri.
Legal Knives in Missouri
Missouri law permits the ownership and carrying of nearly all types of knives, including:
- Switchblades and automatic knives (legal since 2012)
- Pocketknives (ordinary folding knives with blades under 4 inches)
- Dirks, stilettos, and daggers
- Balisong (butterfly) knives
- Bowie knives and large blades
- Throwing knives and stars
- Undetectable knives (e.g., ceramic or plastic blades)
There are no specific categories of knives that are outright illegal under Missouri state law. However, misuse or carrying certain knives in restricted areas can result in legal consequences.
Carrying Knives: Open vs. Concealed
- Open Carry:
- Open carry of any legal knife is allowed statewide without restrictions, except in prohibited locations.
- Concealed Carry:
- You may conceal an ordinary pocketknife with a blade length of 4 inches or less.
- Concealing larger knives or those classified as weapons (e.g., daggers or switchblades) may require a concealed carry weapon (CCW) permit.
- Concealing a knife with the intent to use it unlawfully is prohibited.
Restricted Locations
While Missouri broadly supports the right to carry knives, there are location-based restrictions:
- Schools
- Courthouses
- Airports
- Government buildings
- Private property where signs prohibit weapons
Carrying a knife in these areas can result in criminal charges, even if the knife itself is legal.
Federal Regulations
Although Missouri permits switchblades and automatic knives, federal laws like the Federal Switchblade Act restrict their transportation across state lines without proper authorization. Always check federal guidelines if traveling with such knives.
Special Considerations
- Minors:
- There are no specific restrictions preventing minors from owning or carrying knives under Missouri law.
- Felons and Mentally Infirm Individuals:
- Convicted violent felons or individuals deemed mentally unfit may be prohibited from possessing weapons, including knives.
- Hunting and Peaceable Travel:
- Hunters may openly carry large knives during hunting seasons.
- The “peaceable journey” provision protects individuals traveling through the state with a knife, provided there is no intent to commit a crime.
Penalties for Violations
Violating Missouri’s knife laws can lead to:
- Fines
- Misdemeanor charges
- Felony charges if the knife is used in a crime
Practical Tips for Knife Owners
- Always check local ordinances, as cities may impose stricter rules than state law.
- Avoid carrying knives into restricted areas.
- If concealing a knife larger than 4 inches, consider obtaining a CCW permit.
- Use your knife responsibly to avoid misuse charges.
Missouri’s knife laws are among the most permissive in the United States, allowing individuals to own and carry almost any type of knife openly or concealed (with some restrictions). Staying informed about local regulations and federal laws ensures that you exercise your rights responsibly while avoiding legal issues.
