Understanding Your Knife Rights in Missouri: A Legal Guide

Understanding Your Knife Rights in Missouri A Legal Guide

Missouri has relatively lenient knife laws compared to many other states. Here’s a comprehensive guide to understanding your knife rights in Missouri:

Legal Knives in Missouri

Missouri allows ownership and possession of most types of knives, including:

  • Switchblades and automatic knives
  • Balisong (butterfly) knives
  • Dirks, stilettos, and other slim knives
  • Bowie knives and other large knives
  • Throwing knives and throwing stars
  • Undetectable knives (that don’t set off metal detectors)

As of 2025, there are no specific categories of knives that are strictly illegal to possess in Missouri.

Carrying Laws

Open Carry

Open carry of any legal knife is generally permitted in Missouri.

Concealed Carry

  • You can conceal carry an “ordinary pocketknife” with a blade length of 4 inches or less.
  • Concealed carry of knives with blades longer than 4 inches may fall into a legal gray area.
  • Concealed carry of certain types of knives (like switchblades) in restricted locations can lead to legal issues.

Restricted Locations

While Missouri law is generally permissive, carrying knives is restricted in certain locations, including:

  • Schools
  • Courthouses
  • Airports and planes
  • Other government buildings

Legal Considerations

  1. Intent matters: Using any knife with the intent to commit a crime can result in criminal charges.
  2. Local ordinances: While state law is lenient, local laws may have stricter regulations. Always check local ordinances when traveling within Missouri.
  3. Federal laws: Be aware of federal regulations, especially regarding interstate transport of certain knives like switchblades.
  4. Concealed Carry Permits: Holders of concealed carry weapon permits may have additional rights regarding knife carry in certain locations.

Recent Changes

Missouri knife laws have become more permissive in recent years. Since 2012, switchblades are no longer prohibited, as long as they’re not used in violation of federal law.

While Missouri’s knife laws are relatively relaxed, it’s crucial to understand the nuances, especially regarding concealed carry and restricted locations. Always exercise caution and good judgment when carrying knives, and consult with a legal professional if you have specific concerns about your rights.
