A small-to-medium-sized (by khukuri standards) full-tang Himalayan Imports khukuri for the wilderness -- chopper, slicer, draw knife, pry bar.. effective and stout.
A quality medium-sized blade (by mere mortal standards) for mixed post-urban/wilderness. Of my small collection, the Son of Dogfather is in that slot -- very nice handle, and the meaty slab of SR-77 is just right.
If the range of wilderness-only options were slightly expanded, I'd take a large but very light folding-frame bucksaw with spare blades and a 5" INFI all-arounder.
