I was given my first Swiss Army Knife as a present when I was a teenager. At that time (and possibly even now, many, many years later) it was the most useful thing I have ever been given. I still have that first knife, but have bought two more since, each with a different collection of tools. I would think that barely a day has gone by since receiving that first knife that I haven't made use of one or the other knives in some way. They've been used for all sorts of things, from pulling out splinters, holding needles in a flame to sterilise them, cutting broken nails, cutting cake (there was cleaning between the nails and cake !), opening bottles, opening plugs to changes fuses, cutting cables, doing PC support replacing cards inside computers, small cutting jobs in the garden etc. You name it, a Swiss Army Knife can usually do it. The only situation I have been in where a Swiss Army Knife is not really my chosen tool is when really in the middle of nowhere, when doing tasks that require force as well as cutting. For that, a fold out blade is not really the thing to be using, better in that case to use a proper bushcraft knife. But for all those everyday jobs in everyday situations, a Swiss Army Knife is usually perfect. The Victorinox 1377300 Army Knife Handyman Red is the one I have that gets most use.
