>>124625If you are already putting a backpack together, forget the "survival kit" knife. You want a knife that is actually full tang and not simply a hollow piece of plastic with the blade barely attached on one side.
My halfway recommendation would be to go here (used his services before and he does great work):
http://www.godspeedtactical.com/for-sale.htmand buy an ESEE-3 from this guy with the sheath, and ask for a firesteel holder attached. That way you still have fire-making capabilities with just your knife in case for whatever reason you lose your backpack. Just be sure to strip the spine on these since they are coated.
