People have actually broken (good) axe heads in cold enough weather, and axes (in general) are tougher than knives because they are thicker, and they don't need the same degree of edge retention. I've studied steel a bit (I know the difference between pearlite, bainite, and tempered martensite) and quite frankly I'm amazed that knives can be as tough and sharp as they are. The one thing that I know is that there is always some level of compromise in a blade. A machete is tough, but wont hold an edge worth a darn, my Wustoff chefs knife cuts like a razor and hardly ever needs a "real" sharpening, but I bet I could snap it with little effort. A good survival knife is a jack of all trades, but they do have their limitations.
