There is no other iron on the planet. So meteorite iron is the only iron, from which skilled smiths can make steel, which obviously beats the crap out of the bronze weapons otherwise available. In a world where steel doesn't otherwise exist, its strength, hardness and resilience would seem pretty magical.
