Knives never go in a pocket or cabin bag, I'm very careful to move all knives into my check bag usually aout a day before just so I don't make a mistake.
I think the leatherman or crappy fake swiss army knife may be the 'knife' to bring. No chance of people being upset with those and I still get to have a knife just not my spydies
Its a shame the to be legal, unoffensive and reasonable causes honest people to be this worried. My poor caspian was finally going to get a chance to shine, instead paranoia and "Gotta be legal gotta be legal, don't want to get in trouble" is wrecking that.
Do criminals all get together and say I think I'm going to mug someone tonight, but I don't have a permit to conceal carry my gun, what should I do?
