When looking for a survival knife recommendation, most of the replies you get will be this "badass" 2 lb hunk of steel that can chop down a sequoia tree in two whacks and is practically indestructible. In reality, the best survival knife is the one you have with you. Having an edged tool on you at all times is one of the best things you can do. This gives you options and capabilities that allowed the human race to flourish from the caveman to the great pioneers. You can defend yourself (last ditch option), make tools, and even occupy downtime by whittling which keeps you busy. Your everyday carry knife could possibly be the knife you are going to have when your stranded up the creek without a paddle so to speak. It doesn't matter if it's the blade on your Leatherman Wave, Victorinox Classic, or even Spyderco Military! If it's not on you, then it naturally can't save your life.
