idk.
I always thought of BC as doing the smaller more finesse work using a nice kind of small handmade scandi ground knife.
I often think of it as notching, skinning (maybe), whittling, and such.

that is what I think of as "typical" BC.

I don't think of it as emergency or "survival" type of stuff... for me at least.

or as mac once put it "why do I need to be able to whittle a spoon to survive?!" (or something along those lines)

I often think of a survival knife as being about a 7-10" bladed knife that can both chop, , pry, and be sharp enough to whittle, notch, and you should be comfortable enough with it in many different grips to do the finesse work.

but thats JMO and I didin't really cover all your points, but I thought I'd throw my opinions out there, even though I'm no expert on the subject.
