Just considering hour's (meaning "human") story. Knifes, as weapons or tools, started with and extremely sharp esxtremely brittley nature (silices here in europe, obsidian mey be in south america) and then "uprgaded" to a most softer and duller, material: cooper, bronze, then iron.
But for some millenniums, when blades where real "vital" items, the preferred choise was thoughness over any other features. Anywhay I still see persons whorkers in agricoltural as in houses industry, hunters, shepards and mountain men, gaving theyr's preference to a simple, economical, but reliable steel over any superalloy.
stupid I know
