My second favorite Survival Knife would have to be a Kukri, made famous by the Gurkha's. It is long and curved full tang made from leaf spring steel (shock absorber metal often used in Mercedes-Benz). They are usually about 12-14 inches long looks like a boomerang almost.
They have the durability to chop through cement re-bar and then some. They have a pretty flat handle at the bottom for pounding stuff, and grooves in the handle.
Often comes with two smaller knives for eating which are included in this photo.
I think you should carry more than one knife, such as a Kruki and Becker campionion. You don't need expensive knives just durable ones. If you include a Kabar and a filet knife in your pack you should pretty much about cover all tasks.
I like the Tracker but don't feel it has the heavy cutting power of a Kruki. The Kabar is just because of my military background, and it was versatile. I carried all three everywhere in the world.
