Part of the problem comes from the news media. The FAA clearly says that knives may be carried in checked baggage on their website. The media, however, is just saying no knives and the people who are putting up signs are probably not even reading the directives that the government is sending out. I recommend that if enyone is traveling, that you download the FAQS on the FAA website and that you pack up your knives well before you get into the airport.
