We just returned from a week's camping in the desert, so I'm a little slow in adding to this thread.
Anyway a SAK rescued us & made me a hero.
Early in our marriage, my wife & I took a impromptu camping trip at a small, remote fishing resort.  My new wife packed little food, planning instead to buy our food at a local store.  Naturally the lake's store had available only the rudiments: macaroni, cheese, Spam, canned asparagus, & a bottle of wine.  Much to my astonishment, she showed her culinary genius & prepared a delectable casarole.  But she had forgotten to pack a corkscrew.  Fortunately, I had my first SAK, a Spartan with its corkscrew.  I debonairly (or at least I felt that way) extracted the cork,  and we feasted.   <img src="images/graemlins/cool.gif" alt="" />
I'll never forget that save.  Thereafter, I've always remember to pack a SAK with a corkscrew, now usually a Swiss Champ or a Rucksack since I ordinarily carry a Fieldmaster which has a phillips screwdriver instead of a corkscrew; I'm not sure that a Huntsman with its corkscrew wouldn't be wiser.
I admit it.  I am a SAK chauvinist!

SAKs forever!   <img src="images/graemlins/grin.gif" alt="" />
