lies!! the advantage of iron is that it can be sharpened by grinding where bronze must be reforged
That's almost definitely not true. I have no idea what moron put that in wikipedia, but it seriously needs a citation.
Especially since bronze is not "forged" like iron is. Bronze tools were cast to shape, then cold-forged/peened to work-harden areas that needed to be harder than the rest (like a cutting edge).
Bronze is reasonably homogenous, and thus would be easily resharpened by grinding, though it was historically peened to sharpen it, then recast when the metal fatigued too much. Probably because bronze was too valuable to grind any off.
Wrought iron has strands of glass slag all through it, which would be exposed by grinding, resulting in an inferior edge. Most iron tools were
also traditionally resharpened by cold forging. Look up how to sharpen a modern reproduction iron scythe. Do you grind it? No! You put it on an anvil and tap the edge with a hammer until it's sharp again.
Good quality bronze is stronger than iron in pretty much every property, will take a finer edge, and will also hold that edge longer. The only disadvantage is that bronze is a little bit less elastic than iron, which is what allowed iron to be used in larger weapons.
High-carbon steel, on the other hand, is far superior to bronze, much moreso than bronze is superior to iron.
I eventually decided that the "iron" in 3D DF must have been a very poor steel, rather than a true wrought iron. Because wrought iron is
not stronger than good bronze.
