I couldn;t agree more about the quality of the Bahco line of tools.... but really, I'd prefer a chainsaw... Stihl 18" would fit the bill. ....And, if I was building a shelter, I'd probably want a Milwaukee worm-drive saw with me or at least 2-1/4 horse Skilsaw.
Problem is, they're not practical to carry in my pack. Now, I haven;t tried this, I just know tools well enough to know they won't fit (or if they do, there'll be little room for anything else). Plus, I know the generator I'll need to run them won;t fit!
Seriously though, when I'm camping I carry a folding pruning saw even though we rarely use it. It's there if I need it.
BUT, every time I logon to ETS, I always figure we're talking survival ... with little if any luxury...So, the wire pull saws have their place. If it breaks (which it eventually will), you can still make it work depending on where the break occurs. I like the idea that they're light and small enough to fit anywhere.
