The best survival knives are the survival knives you trust with your life AND that you are comfortable using. I use this analogy A .22 pistol is much more effective in the hands of someone that knows how to use it, than a 30-06 rifle is in the hands of someone that doesn't know how to load the bullets or is afraid of it.
