There is a full tang knife, a folding knife, and a multitool knife in general. But if I can only carry one, I would carry a full tang knife. I usually carry all three, and I also carry a machete or a kukri, and a saw. The benefit of a full tang knife is the blade and the handle is one piece of metal, and there are varying materials used to make the handle. The last thing I need is a knife failure where the handle and the blade is separated. The knife is practically useless at that point. Always have a solid full tang knife in your kit.
