My small first aid kit I carry has a pari of bandage scissors that have a 1inch blade and total length of 4 inches, it pass fine. I also have a knockoff P-51 with a spoon on it that is in the first aid kit as well they may look but I get on the plane with all my stuff. Thouhg my wife was depresssed because they took here suntan lotion, guess I didn't pay attention to her packing.
Cheers
