Favorite Zelda Item

With the "new" trailer for the Zelda game for the Wii U I was thinking about older zelda games and the item that are in them and might be brought back. My question is what is your favorite item/s from any zelda game and why? I like the magnetic gloves from oracle of seasons/ages, and because of the puzzles it brought. Imagining a 3d puzzle utilizing the magnetic gloves would be really interesting to bring back. Any thoughts?
