I have the kampr and the becker bk9 bowie. The kampr Ive been carrying for a few years now. It is my companion when hiking, or camping. I have had no problems out of it whatsoever.
Although stainless is less shock resistant, this has not been a problem. The convex edge can be easily be stropped on carboard and is wonderful for chopping.
I also, use to own the magnum, was never too fond of it.
The kampr is a great "all-around" knife as you can chop, slice, or whittle (make fuzz sticks) with it. Its not heavy, but heavy enough to do some great light, to medium chopping. You can both cut vegatables with it, or make a small shelter.
The aus-8 while stainless, will discolor some of you do not take care of it, but unlike the becker's blade it is much more adapted to the outdoors. And worrying about it rusting is not a big factor (the beckers edge will tend to collect rust more in damp weather, of course its carbon so this would have to be expected).
The bk9 bowie I like, but it is much too heavy for hiking, or backpacking.
The difference in weight between the two is very noticeable.
