My personal conclusions from various sources over the years: You can not carry an 'offensive weapon' (an exception here shortly). A bowie knife would be an example. A concealed carry permit pertains to a firearm (pistol) ONLY. It does not include a 'large' knife, baton, rifle, etc. The 'rule of thumb' is: If the blade is longer than the width of your palm - it is questionable. I have decided to carry a tool with a 3" long blade for opening boxes, cutting string/rope, emergency vehicle belt cutter, etc... (My legal firearm is a Ruger SP101 .357 or an HK Tactical .45 w an extra clip.)
