Check out Belfast International! There is a large perspex box 1m x1m  x1m, into which you can volunteer "prohibited items", prior to being  embarrassed after a search. Amongst the multitude of scissors,  screwdrivers and nail files there is an axe! Well, a large kindling axe  to be truthful but a sharp, heavy, lethal blade on a wooden handle, all  the same! Now I don't know if some farmer had it in his carry-on and  thought, "Oh s**t, better dump this", or some wag deliberately brought  it to the airport just to chuck it in the highly transparent box,  knowing that they can't touch him prior to scanning; or even if the  guards put it there as an example of the range of things they expect us  to leave at home but I desperately wanted to go back in to Belfast and  buy a large machete or some-such and just deposit it. As expected Mrs D  wouldn't let me! "Don't be so stupid! Do you want to get us arrested?" Hmmm!
