I don't own what I would consider a survival knife, I have a set of three knives I use for chopping, cutting and food prep.
To me a survival knife should be able to help to defend me from an attack, to chisel through breeze block, to chop, cut and slice through anything I throw at it and to be almost impossible to destroy.
In short, to me, one set of skills (bushcraft) is not an evolution of another set (survival) but is more the difference between a combat sport and a martial art. One is to just get the job done without limits in any environment, the other is to perform in a specific arena. Of course there is overlap but that's a whole other thread.
I do keep toying with getting a BK2 and having a play with something I would consider a good survival knife starting point. My knives could be pushed into a survival situation and would probably be ok but while well made, they use natural materials and the steel is unforgiving of damage.
There are two kinds of people in the world: those who can extrapolate from incomplete data
