A young family at an ajoining table seemed fascinated that somebody would carry a knife for THAT and asked what the knife was, its tiny size seemed to impress them! This all goes to show that knives used correctly in public helps offset all the hysteria in the media, as they are shown as valuable tools. I've always hated biting chunks out of fruit, I want to slice them and prepare them, the kids at the table seemed a lot more interested in the fruit when it was prepared into portions anyway.
I'm not real sure of the psychology behind it, but I noticed that both our own kids, and others seemed to be much more inclined to eat an apple, pear, or any other fruit or veggies if it was "prepared". It became a traditon for the kids to bring dad thier apple to be sliced up with the pocket knife of the day, a process they seemed facinated by. Our daughter in particular loved for me to slice her apple into quarters, and then share it with her by having a part of it.
These days our grandkids insist on using their pocket knives to slice up apples, bell peppers, pears and such. I have to admit it seems a bit more genteel to neatly portion up what you eat rather than just bite chunks out.
