Tools should be used for their intended purpose - chopping wood with a tiny little knife is not a good idea. And why would you. I have camped for a long time and have never, ever, ever , not once, ever HAD to chop wood. I have chopped wood with a hatchet, but I did not have to.
Exactly which survival situation are we considering that would necessitate the use of a fixed blade over a folding knife?
Knives are cool- and the one you have shown in your post is a real beauty - but chopping wood with a knife is about as useless as shaving your butt hair with one in my opinion.
