This article was created to be a brief synopsis of the law according to my understanding and is not legal advice. Knifeade is not a legal service provider. Using this site does not create a client/lawyer relationship. Because knife laws can be interpreted differently by different people and entities it is recommended that you consult legal counsel for specific information and guidance.
Kansas is one of the few states lenient to knife owners, especially after the law amendment in 2013. This state’s knife-friendly stance makes it a favorable place for knife enthusiasts. However, it’s crucial to understand the legal boundaries surrounding knife ownership, carrying, and usage in Kansas to stay compliant with the law.

Does Kansas Have Statewide Preemption Knife Laws?
Yes, Kansas has statewide preemption knife laws. This means that local municipalities cannot implement more restrictive knife laws than those provided by the state. The law ensures a uniform set of regulations concerning knife ownership, carrying, manufacture, transportation, sale, or transfer across Kansas.
Any municipality law that contradicts these state provisions and was adopted before 1st July 2014 is considered null and void. No action will be taken against individuals violating these prohibitions if the offense occurred on or after 1st July 2013.
