@Lego lord: Actually, Toph can only metalbend because she can see by feeling. If she wasn't blind, and therefore relied on sight a lot more, she couldn't sense the impurities in the metal. In the episode where Toph first metalbends, it first shows her putting her hands against the cage, where the wave of her senses rolls out and the impurities that can be bent are represented by sparkles.
