Understanding Your Knife Rights in Kansas

Knives are versatile tools with a wide range of uses, from everyday tasks to outdoor excursions. However, knife laws can be complex and vary from state to state. Understanding your knife rights in Kansas is essential to avoid any potential legal issues and ensure you’re carrying and using your knives responsibly.

Kansas Knife Laws

A. State Laws

Kansas has remarkably permissive knife laws. The state places very few restrictions on the types of knives you can own, carry, and use. Here’s a breakdown of what you need to know:

  • Definition of a Knife: Kansas law broadly defines a knife as “any cutting instrument consisting of a sharpened or pointed blade.”
  • Blade Length: There are no statewide blade length restrictions in Kansas. You can legally carry knives with blades of any length.
  • Illegal Knives: The law does prohibit certain types of knives, primarily those designed to be hidden or used primarily as weapons: 
    • Ballistic knives
    • Switchblades (Automatic knives)
    • Blackjacks, slungshots, billy clubs, sandclubs, metal knuckles
  • Exceptions: The law may have exceptions for using knives during hunting, fishing, or other lawful activities.

B. Local Laws

While Kansas has no statewide restrictions for most knives, specific cities or municipalities within the state may have their own knife ordinances. These local laws could be more restrictive than state laws. Important points to remember:

  • Check Your Local Ordinances: Always research local regulations governing knives in your specific city or county. You can find this information on the official websites of cities like Wichita, Topeka, Overland Park, or by contacting local law enforcement.
  • Potential Restrictions: Local laws might place restrictions on blade length, carrying methods, or prohibit certain knives in designated areas.

Carrying Knives in Kansas

Kansas allows both open and concealed carry of knives. Here’s what this means:

  • Open Carry: You can legally carry a knife visibly on your person, in a belt sheath or holster, for example.
  • Concealed Carry: You can carry a knife hidden from view, such as in a pocket or bag. There are no permit requirements for concealed carry in Kansas.
  • School Property: Carrying knives of any kind on school grounds is generally prohibited. Consult your school district’s policies for specific information.

Using Knives in Kansas

While Kansas laws are lenient towards owning and carrying knives, it’s crucial to understand restrictions on their use.

  • Threatening Behavior: Using a knife to threaten or intimidate someone is a crime, regardless of the blade length.
  • Self-Defense: Kansas law recognizes the right to self-defense. You may be justified in using a knife to defend yourself or others if you reasonably believe there’s an imminent threat of serious bodily harm. However, it’s important to seek legal counsel if you are involved in a situation where the use of a knife for self-defense is involved.


Kansas offers its citizens broad freedoms when it comes to knife ownership and carry. It’s essential to be aware of restrictions on specific types of knives and potential local ordinances. Remember, carrying a knife is a responsibility. Always use knives safely and avoid situations where they could be perceived as a threat.
