Cowardism, our national response to Terrorism, steals my pocket knife every time I go to the airport.
The next day I need to cut a piece of string and Dammit! where's my knife?!! Oh yeah.
My society in an orgy of panic needs it for self-inflicted injuries.

So like any good tool-using ape, I grab whatever knife is handy, rub it on something til it's sharp, and when I'm done opening the letter or whatever, I roll the blade up in a piece of paper, fold the end over, and pretend it's a pocket knife.

Take that, you unelected King George! The founding fathers and I despise your Tyranny!

    In the US, we can have knives and things in baggage, as long as we put it in the belly and not carry it on. Guns too.

    Good idea in theory, but the xray machine will still pick up the blade shape. I thought of this a while back, wrap up the knife/blade/pointy thing in tin foil. Fold the foil into a flat square shape. The xray machine will see a square thing that wont look anything like a blade.

    Actually, pvc works great for potato guns and devices as such... pneumatic cannons, confetti cannons, etc... The main thing is that you have to be sure to use a bonding agent so that the pvc pipes wont come apart during launching. Yikes!

    There are very sharp half-serrated composite (glass embedded plastic) knives available, but the act of carrying a concealed knife on airline may bring felony charges and a police beatdown at the airport. Your improved butter knife is pretty cool though.

    good idea we're goin to florida sometime during the summer ill have to try this

    Ok, for those that didnt understand the poorly phrased political comment. He meant that airport security takes his pocket knives away from him, leaving him without a pocket knife. So, he takes any old knife, or makes one, and wraps it with paper to make it a pocket knife. And why the politics on instructables?

    this makes no sense, man


    "Take that, you unelected King George! The founding fathers and I despise your Tyranny!" What does that have to do with taking a knife onboard a plane? Are you implying that if Bush wasn't president you would be allowed to take knifes onboard planes, you liberal hippy douche?
