The only knives I own that small have locking blades because y'know, it's SAFER when the blade can lock into place. I think it's kind of stupid to have to check a common utility knife but this rule really isn't much better (if any) than the ban. As far as firearms go, sure, I'd love to be able to carry my piece on board with me but I also know there are a lot of stupid wankers out there responsible for NDs every year so I'm okay with having to check it too. I could see room for having some kind of safety certification to enable you to carry onboard but honestly, it's just not going to happen with this administration so not worth the gray hairs even thinking about it. I'd rather get emotionally worked up over that jackass Holder continuing to be AG and the stupid gun laws being passed in Denver.
