I grew up close to where you live over in North Van. Maybe I am a bit old fashioned on my axe preference for this one. Every summer, I spent it in the woods with buddies building forts and lean-tos with axes. That was long before the tree-hugger days and it was common to drop a number of 2 - 3 " sized fir trees and consume them in the process of making a shelter, along with fire wood.
(post script - note this area is now developed as residential but back then it was forest).
A 1" tree may be practical for the back part, but for the frame we always used 2-3" posts. If we wanted to build a bed off the ground supported by standing trees, we also used 2-3" posts. (note similar shelter built by Ray Mears).

I was merely saying the knives tested would have kept the average person chopping for quite some time to set up a formidable shelter, "if" that were the scenario. Here's a fairly good example of a poor fellow just giving up on chopping a tree.

For finer work, yes of course a blade of the OP's size works great, that's why I like my ESEE 4. Surprisingly enough, a tremendous amount of finer woodwork can also be achieved with an axe in the right hands.
Anyway, appreciate your points raised. BTW, if you want to do a great trek you should look into the Bowron Lakes canoe circuit up in northern BC by Barkerville. I had the opportunity to do that two summers in a row while living over there. It takes about 7 to 10 days of canoeing and portaging. A good place to have a knife and an axe.
