My brother has a 35 year old felony from when we were kids in Calif but we live in Mesa, AZ now. We both carry Cold Steel Vaquero Grande 6 inch Folders clipped inside pocket. We want to find out if it's a crime for him to be carrying this knife around either open or concealed. It's a real nasty weapon that can only be considered as such. My brother can't get this felony expunged due to the violent nature of the offense, but he still needs to be able to have some means to way to defend himself.
