I personally am on a Benchmade kick right now. I have a mini-Griptilian sheapsfoot plain edge but I ordered a full size
Limited Edition Griptilian sheapsfoot combo edge that should be here Monday. I love Benchmades. Not to say they're aren't other great production knives - Spyderco, Kershaw are fantastic as well. You want a good steel in a hight end knife, currently CPM S30V is the way to go, I don't have a knife made of that - yet. My two Griptilians are 154CM which a good steel and they have a good grain.
If you want to spend the money, you can get the totally freakin' awesome
Doug Ritter Survival knives. They're basically S30V Griptilians, it was a collaboration between Benchmade and Doug Ritter. I could go on, but I dont' want to cost you too much money. And you want to see your money disappear even faster, get looking at some custom jobs.... Good luck!
EDIT: I forgot to add that in a survival situation you want to stay away from the black coated blades. They look cool and all, but you can't use the blade as a signal mirror like you can with a satin finish blade...
