When the handle is hollow, it means that the blade and the handle are separate, often different, materials, and there is no tang. The blade is typically just welded to the hollow handle tube, creating a weak point where they join–especially with the leverage of a long blade. This weld is where it would break, probably when you need it the most. If it came down to me against the world, I’d certainly hope my knife had as much spine as I did (or much more). For this reason, folding knives and hollow-handle knives would not be on my wishlist for a real survival situation. Instead, give me a beefy, full-tang knife that’s razor sharp and easily re-sharpened in the field. And give me a little pouch to carry all my survival doodads and trinkets. Handles should be for holding, not for storage.
