Well, I can say because I happen to have just seen the episode the other day that the line is "Even your famous mother could never bend a metal that pure." (might have one or two words off)

So I don't think bending platinum is impossible so much as it is more difficult than other metals, as it is more refined, just like other metals are harder to bend than regular earth. Bending rocks is easy enough, and as materials get more and more processed, the further from proper earth, and the harder to bend it becomes.

That being said, what are RWBY weapons made of, and can Toph bend them?
