Well, I know the OP said "apart from SD", but I think that is the only reason to carry a mega-folder other than biking/hiking/backpacking were it might fit inside the pack or the pocket, but have twice the reach of a fixed blade in the same total length when carried.
I mean, some folks here carry a large Vaquero (6in. blade) to trim off branches and plants that get on the way on biking trails and routes, and I use my Gunsite or Rajah II to chop off little branches that I can't reach with my hands and pruning shears, but get on the way when trying to maneuver large loppers and retractable scissors/pruners.
The Ti-lite I messed up fits inside very tight places, digs into the ground easily, and saws vines and roots like a champ
I find it more efficient, and less tiring.
So, while I carry these for SD only:
I carry and use these when working in the woods, and they have their place there:
And I use my Pocket Bushman (4.5 in.) when it's the "temporada de calçots", something like "Tarraconese-onion season", when we collect, cut, peel and eat hundreds of these "calçots", a type of onion from Spain, in massive parties and meetings. The PB holds up to the task of diggind roots, and sometimes batoning dry branches and twigs.
PS: This here are "calçots", as we call them in Catalonia. Delicious
