Been there. No expert, mind you, but have seen a few characters that qualify... We just moved south from the NWT last year, and there are plenty of folks up there living the mountain man life. Trapping for money, hunting and fishing for food, living in a remote cabin on a river. Not as prolific as even a few years ago, but still not uncommon. From what I've seen they give little thought to a knife other than what works for the task, which is first and foremost, processing game. Ulu's are common, as are Grohmann's, CS Master Hunters, and the outdoor edge swing blade. Those Kershaw multi blade kits are popular too. The most common knives are Victorinox butcher knives and Old Hickorys, and lots of guys have em all in a canvas roll. Everyone has a Leatherman, everyone has a skidoo, everyone uses canvas McPherson tents and airtight stoves, everyone uses Jonsered chainsaw and hardware store axes. Loyalty to a brand usually extends as far as what the local store carries, so they can get warranty service. The odd few pick up something nicer at Supply Sgt (knives) in Edmonton when they drive down with family on the winter road, but that's about it. Bic lighters, firesteels and Redbird matches. A sleeping bag in the NWT is called the Woods 5-Star.
For clothes, it's fur, canvas and wool all the way. New stuff like goretex gets tested by everyone as they come along, but they don't last like traditional garments, and are not as easily mended. Down and Gore are usually relegated to town visits only. Sorels - town. Mukluks - bush.
Guns are small caliber, usually .223 or .243. Plus everyone has a 30/30 and a 12 ga., as well as a 20 ga or .410 for chickens(ptarmigan).
Obviously, when I say everyone, I'm making a generalization. One or two people use Stihl...
