Naah. They will change their minds here.
The flight attendant's union is on the case.
While admitting it will not risk safety for the flight crew/aircraft, they think they will be in danger from this.
Actually, I think the reason that they are changing their minds is that most foreign countries allow pocket knives with short blades already, and a bunch have been confiscated by TSA when they arrive here and change planes.
Heck, the Dutch won't allow hunting broadhead arrowheads or fixed blade knives in CHECKED baggage even on a connecting flight....
