After reading what you want to do with the knife, may I suggest a couple of makers you didn't mention? Newt Livesay & Ray Ennis. I have knives by both (& others, including Randall). The knives from these gentlemen are "first among equals" in my collection.

Here's the web page for Newt's "Wicked Knife Company." My favorite is the Air Assault. Check out his Bow Hunt'n Buddy--it may be what you're looking for.

And this is the web page for Ray's Entrek Knives. I'm currently carrying a Javalina in my pack in the truck.

I'd grab either of these before my Randall--though I wouldn't be unhappy with it in the bush, either.

Good luck.
