I have a SAK soldier, and a few other smaller SAKs (whose names escape me at the moment) and have been pretty happy with all of them. They also make a smaller version of the soldier which I think it called the Cadet. Although the metal handled knives tend to be slimmer and look beefier, you may also consider one of the plastic handled SAKs as they come with tweezers. I've found the tweezers to be pretty good at removing slivers, which can make your survival situation a little more comfortable. IMO any SAK you can squeeze into your kit would be a good choice.
