I'm interested in any info you guys have about uses for a survival knife, beyond the obvious. I'm talking about real utilitarian stuff: crafting tools, shelter and clothing. I've got a fair amount of training in how to fight with a knife, and a crude understanding of some survival skills, like using the knife to scrape the fibers under tree bark, then using the fiber to affix the blade to a stick, for a spear. But I'm seeking some expert knowledge, maybe some of you guys that have done SERE training, or some of you woodsmen out there, would be able to weigh in on this. So if some of you have a few really clever tricks that you know of, please post in here. I'd also be open to suggestions on good books related to this subject.
