For me, a B11 is the perfect light weight chopper. It makes quick work out of building a shelter. If I owned a DFLE it would likey be a toss-up from everything I've heard about the legend.

The Skinny ASH1 is my favorite belt carry all around camp knife. There are bigger and thicker, but that is all I need and then some for any situation. A similar Res-C in ThINFI or Thin77, well that would be tough to beat.

The S5LE and RMD are as good as it gets in that size for hiking, and would not fail you in a survival situation. It'd be real hard to improve on those two.

An orange Ritter RKS MK1 is always in my pocket. I could survive with that if needed. Even the regular Grip is fine.

I think alot of survival dream knives will be found in the new 11 and basic series. There looks to be a whole lot of well thought out, performance oriented blades in the works.
