Dave, when you say "Durable, Fixed Blade For camping/hiking" I'm guessing you mean chopping and whacking, not skinning and food prep?
I'll give you my two great bang for the buck beat 'em ups - Cold Steel Light Khukri (mine's the o-o-o-o-l-d one - 1st gen LTC,maybe?), and Spec Ops Survival Bowie. There are better choppers, I'm not sure there are better choppers for the money (as long as you want a knife, not a machete.) Now both of them had some quality control issues - basically, with Cold Steel and Spec Ops, there's just no guarantee you will get a knife with good heat treat out of the box. But they've both got decent warrantees and customer service. So test them immediately, and send 'em back if they're soft.
I've only had the bowie for a year (damn, just checked - EXACTLY a year yesterday! :thumbup: ) but I've had the khuk something like ten, and I have beaten the living crap out of it with never a problem.
