Having lived in Nepal many years ago, I can say that a good kukri knife can do great all-around service as a knife and hatchet. For fine work like slicing meat and veggies, you hold the knife still between your feet or knees and move the food against it. That said, a proper kukri is actually a set which in includes an unsharpened, knife-shaped sharpening steel and a small knife (about a 2" blade) for fine work. I think the combination of a small Mora knife and cheap Cold Steel kukri, less that $40 for both, would be a very effective and inexpensive survival set.
