I just like my sog's and emersons. On my person I carry around (all the time) my sog powerlock, my magnesium/flint fire starter, my lumi nox watch, and either my sog vulcan or my emerson commander (I like to rotate these as to even out the wear on the blades). So, if I were to be thrown in the survival scenerio provided, I think I would be pretty well off. I am an eagle scout and just having all of this extra stuff would be awsome. I'd probably start my own city with all of the crap in my pockets (just kidding). I know several people put fixed blades as the main thing to choose or an axe, but I'd be happy just having my EDC on me (emerson commander or the vulcan). Both of these are fairly thick blades for a folder, and are made of good steel. The emerson I like because I could tighten or loosen the pivot in case it gets loose with just my thumb nail, this going by the lost and never being found scenerio, and my vulcan because it is very thick for a folder, .16" stock and 3.5" blade. I know the length of these is alot less than the 2 to 3 foot machetes and other stuff, but they work for me and I carry these all the time. As stated above by a few people, who actually runs around with an axe or a 2 foot blade? I'm not trying to start anything, just stating the obvious.
Now in the 'never being found' scenerio where I HAVE to stay put, I would use my knife and flint, not including my powerlock 'cause that is not in the scenerio, and start burning the base of the logs to act as my axe, the indians did it so I can too. Plus, I'm sure we've all seen survivorman and bear grylls in man vs. wild, those are actually very useful things to watch on discovery channel. If I have all the time in the world, after getting my initial fire going and finding a good water supply, I would start my shelter for the night. With my freshly burned logs, and all of my energy still intact (the burning of the logs prevented me from losing precious energy and time), I would set up for the night and worry about food the next day. That ends that scenerio, just keep up the same thing until my city is built!!!
Now, If this is the moving around scenerio, I would probably do the man vs. wild thing and either follow a fresh water stream or head in a good direction to find civilization. Most likely in the dropped in the middle of nowhere scenerio, hopefully you've been watching where your plane has been going, or at least know what and where you are flying over. This would help in chosing a direction. If you are a person who knows nothing about finding a bearing, just do what you can to keep busy, stay put, and wait for sun down or sun up to find west and east. Okay, I'll shut up now, hopefully through all of this my commander will hold out (#1 hard use knifes in the world Emerson Commander Inc.).
