Types of Knives

Legal Knives

In Missouri, individuals are permitted to own and carry most types of knives, including but not limited to:

Illegal Knives

As of the last update, there are no specific categories of knives that are strictly illegal to possess in Missouri. However, the use of any knife in the commission of a crime can lead to criminal charges.

Carrying Laws

Open Carry

Missouri does not have stringent restrictions on the open carry of knives. Individuals are generally permitted to openly carry any type of knife, except in restricted locations or if used with the intent to commit a crime.

Concealed Carry

Missouri law does not expressly prohibit the concealed carry of knives; however, carrying a knife concealed with the intent to use it as a weapon unlawfully against another can result in criminal charges. It is recommended to exercise caution and consider the purpose and circumstances of carrying a concealed knife.

Restricted Locations

Certain locations in Missouri have restrictions on carrying knives, including:

  1. Schools and school buses
  2. Government buildings
  3. Private properties with posted signs prohibiting weapons
  4. Any location where the possession of a weapon is prohibited by federal law

Law Enforcement or Military Exceptions

Law enforcement officers, members of the military, and other government officials may be exempt from some of the restrictions that apply to civilians. These exceptions are typically based on their official duties and the requirements of their respective positions.

Violating knife laws in Missouri can lead to several potential consequences, including:

  1. Criminal charges ranging from misdemeanors to felonies, depending on the severity of the violation
  2. Fines and potential imprisonment
