I remain entirely unclear on what the purpose of this woods knife is? Especially when an axe is already in the pack.
I'm in the woods all the time and generally carry an Opinel N9. Occasionally, if expecting to build a fire, carry a folding saw. And even rarer, carry a 5" fixed blade for batoning, but honestly, an Opinel N9 or N10 will handle occasional batoning. Style of camping plays a huge role.
This past weekend's ski tour destination (no camping).

Fire was handled in an Emberlit stove, which consumes less wood than an open fire, causes less impact and can generally be managed by burning stuff that can be processed by hand. Didn't even need the Opinel for this. Shelter was handled by a light tarp, which saves time and, again, minimizes impact.

If the real question is, what's a cool knife that's fun to carry... well... that's legitimate and hte answer is, what ever makes you happiest. It's your pack and your outing.
Sometimes I carry this, just for the heck of it. About the same size as the Rat 5

But, I find it a bit big for every cutting task except for battoning. IMO, the ideal blade length for a woods knife is about 4". YMMV territory though.
