I am a big SAK fan. I usually carry a Victorinox Scientist (large blade, combo tool [screwdriver, cap lifter, and fairly poor excuse for a can opener], in-line phillips head, magnifying glass, corkscrew w/ small screwdriver, toothpick, tweezers, ballpoint pen, and stickpin) -- complements my Micra and Sebenza quite well. I have owned many models and given them away as gifts, lost one or two, etc.
For more of an all-in-one tool, the Explorer is a great choice. All the standard offerings plus an in-line phillips head and scissors. I have one that is going to be a gift for my girlfriend's cousin whose graduation we are attending tonight in Glasgow, KY. I took the scales off of a Yeoman (basically the same as the Scientist, but with scissors) and put it on the Explorer, so it has the ballpoint pen and stickpin. Now there is a SAK!
I don't know why they don't put the ballpoint pen and stickpin and small screwdriver on all the models.
I just got a Wenger Nomad, which is only my second experience with a Wenger SAK. My first was a Wenger Computer Whiz, which was ok, but they put a T-10 driver on it, and Compaqs use a t-15, so it wasn't as useful as I had hoped.
The Nomad is pretty cool. The main blade locks pretty securely (passes spine whack test) though the lock disengage mechanism would be easy to hit accidentally. The phillipshead is not as long as the Vic's, but the knife is not as long either. Both it and the standard screwdriver "lock" -- that is, they lock when there is sufficient pressure on them. I have already removed a screw from an external hard drive casing without putting pressure on it enough to lock it. Still, it is tight. I will post more when I have tested it better. I thought the scissors would be better than on the Vics. Not sure of that. I am sure that neither is as good as those on the Micra, PSTII, or Wave. Lastly, there is a little wrench. Haven't tried it yet as I have yet to find any nuts small enough to try it on (not that it wouldn't be useful, just don't have any lying around).
I will try to post a more detailed review in the Reviews forum when I have played with the knife more.
Have a good Memorial Day weekend everyone!
