Generally these days there is an obsession with knives that are far too small for most serious outdoor tasks. The assumption a whole slew of other tools will be there kind of makes the whole "survival knife" concept moot. Yes, if you bring your car with your whole living room in it, I predict you will make it... Thank God most "surviving" is done from a computer.
I've found some small tasks are sometimes better done by big, broad, thin edged fixed blades (10" long X 2" wide), because you can chop a crisper and neater cut using the large blade's momentum, whereas with a small blade you are pushing, pushing some more and then the material abruptly lets go, with less control for precise small tasks, such as delimbing neatly very small diameter branches.
For long term heavy use, you want a blade heavy point of balance at least 1/2" ahead of the guard, which means that, even with a decent non-full tang handle (full profile tangs make everything worse), the knife should have at least a 10" blade (11" will often give a full one inch balance point, doubling the balance bias for just more one inch).
The edge should be the thinnest edge possible (about 0.020" at the shoulders, which few makers offer on big knives, usually only Randall offers this from the box) with the widest blade possible, aiming for 2". Even with 1/4" stock, a 10" Full Flat Grind knife will be under pound (16-18 ounces for a 10", 20-22 ounces for an 11" blade), or about the same as the ridiculously heavy BK-2 that has half the blade length, so half the edge holding to begin with... This "object" is basically like carrying a one pound handle.
A blade width of 1.5" is way too narrow, and the stock should be at least 1/4" thick to dampen vibrations. 3/16" blades that are 10" plus will vibrate on wood, and this is made even worse with a full tang: The bigger Randalls have stick tangs and are closer to 1/4" stock (0.22" on a Model 12) for a reason.
The extremely wide blade with an extremely thin edge at the end combines so that even if the geometry is severely damaged by heavy use, just by virtue of the width, edge thinness and weight bias, it will still have the momentum to drive and cut into wood, whatever its condition. The edge strength and edge holding will be greatly helped by an appropriate micro-bevel: Good stainless should hold 15-17 dps with a 20 dps micro while chopping.
Yes a 2" broad 11" blade with a thin V edge will "stick" in wood (10" far less so), but only on the first few hits of a cut (in rain the sticking does get worse, but a simple tap directly opposite the edge will free the knife). Don't convex the edge to prevent sticking: Convex edges are less efficient at everything, that's why they don't stick into wood as much...
Small blades get dull faster, because there is less edge to wear down to begin with. But you'll never hear that in the current nonsense "mine is smaller than yours" atmosphere...
And please forget what you heard about not using stainless, unless all you can bring is a stone rather than a diamond hone. Just stay away from "powder" stainless steel: I have a stainless knife from the 1940s that does better in edge-holding than all the more common current powder steels. I have also seen cheap Taiwanese 420 do the same. Powder steels do hold their edge in rough use, but they lose their apex straightness very quickly: This doesn't matter for slicing (you can slice forever with a micro-folded apex), but for rough chopping it does, because a bent apex just gets more and more misaligned the more you chop.
