Best Survival Knife on the Market

I am going to be going on an extended camping trip in northern Minnesota in the near future. I am probably going to be gone for two or three weeks, I am not really sure. As such, it is really going to be like a true survival situation, and I want to make I am well prepared to address any sort of potential adversity while I am camping. One thing of extreme importance is that I buy the best survival knife that I possibly can.

I want to buy a knife that is going to be extremely functional, such that it will be well suited for a very wide range of different tasks. I will need the blade to be very sharp, and very durable as well. I need to figure out what the best type of material is for a survival knife.
