I've been an admirer (and owner) of Victorinox Swiss Army knives since I got my first one at the age of ten from a really cool uncle. The original multi-tool was the envy of all my buddies.

Nowadays, the comb is pretty much superfluous to my needs, but I have appreciated the wine corkscrew many times. Now THERE'S an essential landout assistance device. Mostly in Europe, but it adds a bit of culture to the desert southwest of America, where innovative uses of seat belts, door latches, pliers, knife blades and even teeth are utilized to open beer bottles.
