Just so you know, when I was eleven, at prep school, I used to have two knives.

One, a "Swiss Army Knife" was a thing of pride - everyone vied to get one with as many different gadgets on as they could. That one I used to carry in my pocket all the time; you just never knew when you would come across a pencil that had not been turned into "pencil cricket" or a desk with a screw that could do with being removed for the delectation of watching the next occupants of it have it collapse on them...:)

The other was one of those "Ray Mears" type things - it folded its four inch blade, kept razor sharp (because there wasn't much else to do with it and one of those sharpening blocks), into its wooden handle. It was meant for whittling my woggle with or whatever it was that we Scouts did, but it occasionally came in handy for cutting up sticky-backed plastic or something like that!

Come to think of it I must have had another one as well - one that had a fixed blade and was worn in its scabbard on my belt whenever I was in uniform. Oh, and if I recall, I bought them all, with my saved up pocket money, myself, and whilst I may well look a decade older than I am now, I did not, I assure you, at eleven!

And the most memorable book I read at school that year?  The Cross and the Switchblade .

I don't remember anyone, ever, getting stabbed, except perhaps by accident when their woggle was whittled too much. We soon grew out of them, when we graduated to the CCF and started playing with guns instead! But I do recall some of the Duke of Edinburgh types remained loyal to their knives. So, blame the Duke of Edinburgh maybe, or Peter Duncan definitely, but the knife itself - what a useful piece of equipment!

Don't they have pencil cricket or woggles that need whittled, any more?

Oh, and I still have a fold-away thing for my pipe that has a blade and a stiletto type poker thing on it - am I going to gaol?
