Kansas is considered one of the most knife-friendly states in the U.S. due to recent revisions in its knife laws. These changes make it easier for residents to legally carry knives. However, just because Kansas has more relaxed laws regarding knives doesn’t mean you should ignore the rules.
Understanding what you can and cannot do will help you avoid any potential legal trouble. This guide explains the key points of Kansas knife laws, so you can stay informed and safe.
What Knives Are Illegal in Kansas?
While Kansas is lenient about knife laws, there are still a few types of knives that are completely illegal to own, carry, or sell. The law specifically bans:
- Throwing stars
- Ballistic knives
According to Kansas Statute 21-6302 (a), selling, buying, transferring, or using these knives is illegal. If you break this law, you could face up to two years in prison or a fine of up to $600.
Knife Size Regulations in Kansas
In the past, Kansas had rules limiting the size of knives you could carry, such as a maximum blade length of 4 inches. But now, those restrictions are no longer in place. As of 2025, Kansas no longer imposes any limit on the blade length.
This means you are legally allowed to carry knives of any size, whether they are carried openly or concealed.
Local Municipality Knife Laws in Kansas
Kansas state law preempts local ordinances, meaning the knife laws in Kansas are uniform across the entire state.
This is great news for knife owners traveling within Kansas, as you don’t need to worry about different rules in different cities or counties. You’ll have the same rights wherever you are in the state, making it easier for you to carry knives without fear of breaking local laws.
Concealed and Open Carry Knife Law
Kansas law permits its citizens to buy, own, carry, and sell knives legally. You are allowed to carry knives both openly and concealed within the state, with very few restrictions.
However, there are places where carrying knives is prohibited, such as:
- Schools
- Government buildings
Additionally, Kansas law restricts certain dangerous weapons. Under Kansas Statute 21-6302 (a), it’s illegal to carry blackjacks, billy clubs, sand-clubs, slung-shots, throwing stars, bludgeons, and metal knuckles concealed.
Violating this law can result in penalties, including up to one year in jail or a fine up to $600.
Limitations on Convicted Felons
Kansas law places special restrictions on convicted felons regarding the ownership and carrying of knives. Under Kansas Statute 21-6304, a convicted felon is not allowed to own certain types of knives.
The knives covered by this restriction include:
- Dirks
- Daggers
- Switchblades
- Stilettos
- Straight-edged razors
Convicted felons are banned from owning these knives, which are considered dangerous or deadly cutting instruments under the law.
Kansas offers one of the most relaxed knife laws in the country, making it easy for residents to legally own and carry knives. However, you still need to be aware of the restrictions that exist, such as the ban on certain types of knives and the limitations for convicted felons.
By understanding these laws, you can safely carry your knife without worrying about legal issues. If you’re ever unsure whether a specific type of knife is legal or not, it’s always a good idea to check the local laws or consult a legal expert.
