I don't follow the logic. Where did I say, anywhere, about magical materials? If we take a hunk of iron, and do magic to make the iron impervious to damage, cutting on a different plane of existence won't help.

Actually The Dragonslayer could cut that too. You see, the antimagic nature of the sword would slice through the enchantment when it hits while simultaneously cutting the iron itself. It's a two-fold attack.
