I am suprised at how many seem to be depending on a folding knife as their primary knife for survival.

I have lots of knives, a bunch are folders but I don't consider any of them as a primary survial knife. I consider a folding knife as one that is already broken in the middle, it has a built in critical weakness.

I carry a SAK Farmer as a pocket knife, always but I also have a fixed blade, with a full or nearly full tang with me on all wilderness trips.
