The BK 9 would make a good camp knife, its a knife that can do knifey things and can chop with a decent exposed hilt for smashing and bashing things. And the handle people say is good. I'd suggest getting Kabar Becker Micarta handles, they may look "pricey" to some but really improve the grip and working with it i find. Regular handles also do well.
The BK 2 Companion is what it sounds like. A nice heavy duty 5" blade for about any thing that needs to be done. It is a highly recommended companion to the BK9, the Sweet 16, I don't have one, looks like a good general purpose smaller middling sized blade. (I have two BK2s they are pretty dang handy).
