For what sort of situation?
If it's the end of the world, I guess I'd grab my CRKT M16-13Z folder and Fallkniven A1. If I'm out in the woods, I'd probably take the Woodsknife WK2 and the Scrapper 5.
I generally always have the CRKT on me, and I carry a Becker BK2 in the car, so I guess that's my day-to-day combo. But I only keep the Becker there because it was inexpensive and I wouldn't care as much as I would with other knives if something happened to it, not because it's my default go-to knife.
