The KA-BAR was designed mainly as a fighting and hunting/utility knife, not as a purpose-built "survival" knife (a concept that's relatively new). Also - those KA-BAR style knives that have the sawbacks on the blunt side are basically half-assed saws that are honesly not good for much. The ones that have hollow handles which can store small items like matches, fishing hooks and the like are certainly better than just a plain old knife. Those multi-tools as sold by Gerber and Leatherman, which are like Swiss Army knives except that they have usable pliers, are really much better for all-around "survival" use than a regular knife. As a combat weapon, the KA-BAR is pretty good, certainly better than a Leatherman or packsaw - but really - if I were going into the bush and could only have one bladed tool/weapon, it wouldn't be a KA-BAR - it would be one of those better quality machetes that have a sawback. I'd take a machete over a knife any day in a combat situation.
