Finally got some time to look over this thread.

I've been looking for a good fixed blade, so thanks for all the ideas.

Here in Colorado critter attacks in the wilderness are rare, but we do have a fair amount of mountain lions, bears, moose, elk, coyotes and ill-intentioned humans. Thankfully my main use of knives on the trail hasn't involved defense but more mundane tasks, such as:

--whittling tinder sticks, marshmallow sticks, extra tent pegs
--prepping camp food
--cutting string or rope
--carving hiking sticks

That said, it'd be nice to have a fixed blade, as it'd be easier to clean/maintain, as well as quicker access in the event of an emergency. (Try opening a basic SAK with numb, icy fingers. Ugh.)

A sawing capability would be nice, as well.
