With all the attention that has been focused on gun laws, many do not realize there have been major changes in laws that regulate knives. The Arizona-based advocacy group. Knife Rights, believes that knives, like guns, should be considered arms protected by the Second Amendment. They do not support any restriction on knives including switchblades,  daggers or even ballistic knives that shoot like spears from a handle. And it’s working. So far 21 states have repealed or weakened their knife laws since 2010. The FBI says while guns are by far the leading cause of homicides in the nation, knives are Number 2, accounting for 11 percent of killings in 2016. Now, Knife Rights is going after its biggest legislative target: overturning the 1958 Federal Switchblade Act, which bans the interstate shipment or importation of knives that open at the push of a button.
