Knives were always allowed on planes. At the very least, they could be gate-checked and placed in a lock box, to be returned at the end of the flight.

I sincerely hope these new rules go into effect. It's about time for at least some of our freedoms to be returned to us. I resent having to give up my survival items when flying. They are there to ensure I have at least some gear in the event of a crash.
