Maybe I should just sit back and MYOB, but Freq, I gotta ask dude, what kind of answer are you looking for?
You posted two threads in two days asking virtually the same question. You had 74 responses on the other thread, and thus far 27+ responses here.
Reading through both threads the theme is pretty much the same, for a short term, emergency survival situation, what you need is A knife, any knife, fixed or folder; preferably a good knife, but pretty much any knife will be an asset.
It only needs to assist you being able to stay warm and dry for a few days. If you get stranded on a hiking trail, you aren't going to become a hunter gatherer overnight. You are going to survive on whatever food and water you have with you, and by staying as warm and dry as possible.
If you want something better then buy whatever bakes your biscuits. (in your other thread I thought you indicated you had it narrowed down to either a RAT3 or Fallkniven F1??)
Your wits, fortitude, ability, and skill are going to be more important than the brand or style of knife you have if you ever find yourself in trouble.
