Of the line, the Arctic knife seems to meet most of what I'd be looking for in a knife ... 4.5 inch blade, no serrations, full tang. It doesn't have all the survival goodies in the sheath like the Mountain, but it does still have the fire steel.
The Desert folder with the integrated fire steel seems interesting too.
That said, I just ordered a Fallkniven F1 so I don't see any of these in my immediate future
