Kansas residents may now carry switchblades, daggers and other types of knives in most public places.
The law took effect July 1.
A group called Knife Rights was the driving force behind the change. The group says the Second Amendment protects the right to keep and bear knives as well as firearms.
Knife Rights lobbyist Todd Rathner says the law makes Kansas one of the knife-friendliest states in the nation because it also prohibits local governments from enforcing any type of knife ordinance.
The law does contain exemptions for school districts, jails and juvenile detention facilities.
