Those knives are cool to look at and collect but lugging around a 9" long 1/4" thick knife seems excessive.

If you wish to chop firewood bring a small hatchet. Probably weigh less with a small hatchet and a medium fixed blade than one large fixed blade.

I have a: http://www.knivesplus.com/ontario-qn-rat7.html
One of my favorite multi-purpose knives, and even at .187 thick it's pretty heavy/big to lug around. Great for small limbs though, and great grip. Also 1/3 the price iirc to the Busse or Fehrman.

In the woods/hiking I like to carry my BENCHMADE 140 Nimravus Plain Blade in M2 steel. Light weight, razor sharp, and strong. Having a small hatchet, or backpack folding / bow saw for wood work is great addition too. I normally also carry my Benchmade Folder for small tasks.. probably don't need it but it's always clipped to my pocket.
