All this talk of plastic and ceramic knives, finding ways to fool the TSA, cracks me up.
Get caught by the TSA on a random search, or because you forgot to take your bottle of shampoo out of your bag,
First off your opinion is noted.
Second I dont carry it in the checkin bagage. I carry it only where a strip search would find it. I pass through airport security with it all the time with no trouble. Its non detectable at this point until xray density scanners are deployed then its pretty much a no go.
Its all about choices you make yours I will make mine.
