Mist curled in the air around him. He burned steel, second of the basic Allomantic metals. Translucent blue lines sprang into existence around him, visible only to his eyes. Each one led from the center of his chest out to a nearby source of metal.

Burning iron or steel would point blue lines at all kinds of metal, assuming they were close enough and large enough to be noticeable.
