Just my opinion, but the ESEE knife you listed has a 1/4" thick blade, which is a monster - just too thick and too heavy to be a useful camp knife.
My own preference is a 4-5" thinner blade. I use an axe for chopping and a shovel for digging. The knife is used for cutting & slicing.
Some folks really get into carbon blades, but I find a good stainless steel blade to do just fine and much less prone to corrosion (rust).
I tell you, you really REALLY can't do much better than Doug Ritter's Mk3. I have one and really REALLY like it.
You can buy lower costs knives, but the Mk3 is very worthwhile.
I'm still hoping Doug comes out with the orange handle slabs for the Mk3.
