Germ - the "ring" you heard coming off of that Iron Mace was actually the sound of Bowhunting Jesus channeling the awesome weapon in your hands, and bestowing upon you the power of the almighty himself.
So it wasn't actually the metal ringing. It was the sound of God.
And when you fired it, somewhere nearby a huge deer just fell over dead. Cause of death: Pure Terror.
