intent of the knife is personal survival.
Our knives best as survival knives have a hollow handle molded, bolted, or welded to the blade. blade thickness is important if using the knife for prying things apart.
combat/tactical, wilderness, urban, water/sea,
survival knife needs to have a fixed blade, it also needs to have a full tang. strength, hardness, flexibility and the ability of the blade to take and hold an edge is all effected by the type of metal used.
