Right To Bear ArmsKnife rights should be protected under the Second Amendment, as firearms rights are, Sparks said. Knife Rights has lobbied for “knife law preemption” in several states, he said, meaning state regulations should preempt any further restrictions that local jurisdictions attempt to impose. Former Sublette County Sheriff Hank Ruland told Cowboy State Daily he didn’t have to deal with much knife crime during his career.
