I'd like to be on a plane that is knife-free and Geneva doesn't seem to be the place to fly from in that case. It makes no sense to allow weapons of any sort on board. On the other hand, the people at EWR seized my wife's nail scissors, which was quite a remarkable act of detection. They allowed her to go back to the main check in with the scissors and put the carry-on in checked baggage in order to save the scissors from the trash heap. If you value your knife, just pack it, even in Geneva. Maybe you want to ask if pilots should be issued knives and pepper spray since the US pilots are asking for the right to bear arms.
