From the AZ Capitol Times:
Cities, counties and other governmental entities would be forbidden from restricting people’s use of knives under a bill winding its way through the legislative process.

The bill, S1153, would give the state sole power to impose regulation on knives. It was approved March 16 by the House Government Committee.

“We believe that knives are essential tools, tools that are used daily by millions of honest Americans,” said Doug Ritter, chairman of Knife Rights, an advocacy group that is pushing the bill.…

Ritter’s group is using Arizona as a launching pad for a national knife-law-preemption campaign.

“It’s a matter of fairness, a matter of civil rights,” he said.
