I recently picked up a BK-2 Ka-bar. Was in the market for a knife like this and caught a good deal. I will use it as a farm knife, so it will get abused a lot. But, also thought it would make a good camping knife...my girls are getting into camping. And in the back of my mind was a survival knife.
I also picked up a BK-11 Ka-bar, otherwise known as the Becker-Necker. This is a smaller, lighter but still tough neck knife. I really like this knife. It is very handy.
I think the pair will make a good survival set. The BK-11 will do most of your smaller work, food prep, ect. And the BK-2 can do your heavy work, batoning, chopping, hammering, processing game, ect.http://www.kabar.com/knives/detail/1http://www.kabar.com/knives/detail/5
Neither of these are fighting knifes, but I think they serve good as utility knifes. I think the knife you have shown is a good all around knife. My thought on the subject of SHTF knife if I could only pick one would be a knife like you mentioned. But my true thoughts, are a good pair of knives would be needed. Although, the BK-2 can do finer task..I am not real good at doing them with it or other big knives. The BK-11 easily does the finer task.
Another interesting knife, I have on order for food prep while camping and would be an interesting SHTF addition. Other knifes would be needed, as well.http://www.blade-tech.com/ULU-Orange-pr-1096.html
