I think that there are some key pints which need to be mentioned here. First of all you suggest that you would not expect to be in a survival situation for more than 4 days or so, or at least this is what you imply, but this cannot the same for everybody. you are obviously experienced and know what you are most likely to need, but i don't think anybody is expected to predict what their exact requirements in a survival situation may be, this is why we prepare ourselves with the best equipment we can reasonably carry. now a fixed blade knife is not all that heavy (the mora's are especially light for fixed blades) and is arguably the most important long term tool (and i think this is your point, you prepare for the short term).

secondly, yes a log cabin is slightly over the top for 4 days, but a lean to is not. you need something you can split wood with to be completely comfortable, maybe not in all situations. it's true that folders are becoming more reliable (but only really at the more expensive end of the spectrum), and maybe they can be used fairly efficiently for small work, but an important factor is how comfortable you are using the knife; blisters you don't want. i have not seen or used any folder which is as comfortable to use as my 5" mora steel as ideally i want a smooth oval wooden handle for extended periods of time.

thirdly, and i think this is the idea put across most often, what if your folder does become slightly loose, or worse break off? i would much rather have a full length knife with a tang to fix than half a knife.

just some ideas.
