Why, immerse oneself in minute scrutiny of confiscated objects, of course.
I can understand why people hand-carry most of these eventually confiscated items : all types of scissors, pen knives, cutters, razor blades. These I don't quite get : forks, butter knives, nails, 4-inch gold nails (!).
But .. a vegetable peeler?
Why on earth would you carry a peeler in your hand luggage? To peel a potato mid-flight? Huh?
