Knives serve as indispensable tools for everything from daily chores to self-defense, and even as pieces within thoughtful collections. Missouri boasts comparatively relaxed knife laws, but understanding the nuances can be complex. This guide breaks down Missouri knife laws, empowering you to enjoy responsible and legal knife ownership.
Missouri Knife Law Categories
This Article Includes
Missouri recognizes two primary categories of knives:
- Ordinary Pocketknives: Any folding knife with a blade of four inches or less is considered an ordinary pocketknife. These generally allow for concealed carry without a permit within the state. Be aware of local ordinances, as cities like St. Louis, Kansas City, Springfield, and Columbia may have their own regulations.
- Other Bladed Hand Instruments: This category covers knives not considered ordinary pocketknives, such as fixed-blade knives, daggers, throwing stars, and automatic knives (switchblades).
Carrying Knives Openly
Missouri law permits the open carry of any knife, with a few important exceptions:
- Restricted Locations: Locations with signs expressly prohibiting weapons, like government buildings, schools, and courthouses, are off-limits for open carry.
- Disturbing the Peace: Openly carrying a knife in a manner that intentionally causes public alarm or provokes fear can lead to legal trouble.
Concealed Carry of Knives
In Missouri, concealed carry of ordinary pocketknives (blade under 4 inches) does not require a permit. However, restrictions still apply:
- Restricted Locations: The same locations where open carry is prohibited also apply to concealed carry.
- Age Restriction: Missouri law mandates you must be at least 18 years old to carry a concealed knife.
Concealed Carry of Other Bladed Hand Instruments
If you want to carry a knife concealed and it falls outside the definition of an ordinary pocketknife, you generally need a Concealed Carry Permit (CCP). This includes fixed-blade knives, automatic knives, and blades over four inches.
- CCP Requirements: To obtain a CCP, you must be at least 21 years old, pass a firearms safety course, and clear a background check.
- Benefits of a CCP: A CCP allows you to carry any legal knife concealed across the state (except in restricted locations).
Specific Knife Regulations
- Automatic Knives (Switchblades): While concealed carry of these requires a CCP, some cities, including St. Louis and Kansas City, outright prohibit automatic knives.
- Dagger/Dirk: Municipalities may have stricter regulations on these pointed knives. Make sure to familiarize yourself with any local laws.
- Ballistic Knives: Missouri law forbids the possession of ballistic knives (knives with a spring-loaded projectile blade).
Important Considerations
- Federal Law: Federal laws may override state laws, potentially prohibiting some categories of knives. Research federal regulations regarding specific blade styles or lengths.
- Intent: Using a knife in a threatening manner, even a legal knife, can land you in trouble. Maintain clear utility purposes for your knife, and avoid suspicious behavior.
- Private Property: Property owners hold the right to restrict knives on their property. Respect signs or ask if in doubt.
