I've actually used all of those in the course of a weekend! Not a typical weekend but except for the redundant survival/folding knives, that's a pretty comprehensive set of tools to set up a camp. I'm not 'hard' enough to chop firewood with a machete anymore, even a ninja-to style one!
I agree that all could be used (and I already own them all), but if you were just buggin out for a week or so, they are not all necessary. I am thinking more like a disaster bag where you might have to evacuate your home, but will be returning as soon as its safe. For a SHTF bag, then all those listed get bumped up on the priority list.
