Just a thought, but your survival knife needs to be your can-do knife for all eventualities.. I'd much rather cut live power cables (remember survival= worse case scenario, including urban) with my S6 than my Badger Attack, as 240V (Britain) bl**dy stings when it zaps you! Micarta Busse Combat knives are tougher and more corrosion resistant, but that good old res-C helps keep electricity, vibration, heat and cold at arms length.. so to me are the winners.
