They did used to use it in swords and other blades and cutting tools back in the iron age (hence the name), but steel is obviously the superior metal for such things.
Meanwhile, the Mesoamericans used obsidian, which take a very long time to get dull if you're using them to cut things like flesh and muscle, either as a weapon or for food. They're pretty good at cutting through bone too if you feel like sacrificing someone at the top of your pyramid. Obsidian does not, however, sharpen obsidian. Stone knaps obsidian into sharp pieces.
But I suppose "alpha males enjoy the company of alpha males because stone knaps obsidian into sharp pieces" would be less pithy.
They didn’t use pure iron in the Iron Age. Even back then knives and swords were made of steel. In the Iron Age they already knew that adding carbon during the smelting process would increase the hardness of the metal. They just didn’t understand why.
And even meteoritic iron is an alloy of nickel and iron.
