Given that even nail clippers are being confiscated at airport, I was thinking that we could use a new kind of cutting tool. One that doesn't look like a knife and one that isn't made of metal. An idea popped into my head. I'm no engineer, so I don't know if this is even possible.<br><br>I was thinking of a round, smallish piece of ceramic that would fit on a keyring. The ceramic would not give metal detectors any grief and the medallion shape wouldn't scream "knife" to security. The entire thing could be sharpened and would function much like a pizza slicer, but with a modified grip. Then if you really needed a knife, you could "pretend" to make use of a handy object for that purpose.<br><br>What do you folks think?<br><br>
