"but what if you are dropped in afghanistan or some country that has a revolution going on?"
I'd use the SAK or Leatherman to make a primitive weapon (like crossbow or bow and arrow) if materials are available, and use it with stealth/stalking technques to get up close, use it, and capture a weapon from a local.
And/Or make camouflage to conceal myself, then use the stalking techniques to sneak up and take an AK-47, LAW, or SAM from one of them! Of course, I'd also steal a good radio to communicate with possible rescuers if I can get my hands on one.
Let's see...what else? I'd try to find a guy about my size, and take his clothes too, so I fit in with the population better. Then I'd find out which side is winning, and temporarily proclaim my loyalty to that side while devising an solid E&E strategy, and a back-up strategy or two or three when the first idea doesn't work. I'd learn the local language for "whatever you say, sir!" LOL!
If it's Afghanistan, I don't care about having a shaving sharp blade, since I'd be using intense concentration to grow a beard as fast as possible.

("Grow dammit! GROW! Think, BEARD!") Then when I approach my rescuers, I'd take off the local clothes (I would have left my own clothes on underneath, concealed, so I wouldn't be naked -- they'd shoot me right away: I know I probaly would if I saw a naked guy running towards me in some far off wild place). Maybe then I'd scrape the beard off to look American again so I don't get shot. I'd hold up my SAK or Leatherman, closed, since they'd know only a silly fellow American would be travelling around Afghanistan with nothing but a small multi-blade knife.
Or I'd use it to make anything else I can think of to get myself on an equal playing field.
Whomever is reading this and saying "good ideas!" please know I'm being largely tongue-in-SAK on this answer....
