What Ranger Psych said, and... You're going to need something that will be suitable for batoning, chopping, shaving, and general cutting. Look into anything Harsey, Reeve, Freeman, Les George, or Spartan make as general use field knives... you will pay for the quality, but the rejoinder to that is, what's your life worth in a survival situation? I'd trust anything made by the guys I mentioned. I own one Bussee, it's a beast, and the only reason it's not an EDC or top of the list knife has to do with some ethical issues from Bussee that date back to the selection of the Yarborough and just after. Look at the Bussee line if you need a comparatively inexpensive, non CPM steel but rugged knife...
You're going to really need to go out and handle knives to see which ones fit yor needs and your hand... a knife has to be comfortable and functional.
