I've tried out a lot of SAKs, Leathermans, traditional folders, tactical folders, Moras, puukkos, tactical fixed blades etc. I'm happy with a clipped Spyderco and a SAK Farmer in my backpack as a backup.
Spyderco Military in BG42 is what I've been carrying. Don't ever find myself wanting a fixed blade in the woods. I just use my knives for whittling, food prep, hacking away at thorn bushes etc. I carry a machete or hatchet if I expect to do any serious trail clearing or chopping. I like the lightweight and prefer having my knife clipped to my front pocket than on my belt.
