Magic Hammer

A Magic Hammer has been present in three Zelda games to date.

A Link to the Past
In A Link to the Past, the Magic Hammer is found in the Palace of Darkness. It serves many purposes as both a tool and a weapon. In both dungeons and the overworld it can remove obstacles from Link's path, allowing him to pass into otherwise inaccessible areas. As a weapon it is useful in dispatching enemies such as Helmasaurs, and is essential in defeating Turtles in the Palace of Darkness. It is capable of shattering the faceplate of the enormous Helmasaur King and is also almost as effective as the sword in dealing with many foes.

Four Swords Adventures
In Four Swords Adventures, a Magic Hammer is one of many familiar items Link has the option of picking up. It can smash stakes, stumps and several other obstacles. By holding the A button, the player can charge the hammer which, upon release, sends out a shock-wave which dazes enemies momentarily. Using the game's upgrade system, the hammer can be made even more powerful, sending out much larger shock-waves.

Phantom Hourglass
In Phantom Hourglass, the Hammer can be found in Mutoh's Temple, where it is very useful in defeating the temple's boss, Eox. This time, the Hammer is a ranged weapon; it can attack any panel in Link's sight. This is because not Link, but his Fairy companion Ciela uses it. Link merely makes hand gestures to tell her where to swing it. It's primary use is in pounding down rusty switches that cannot be triggered normally. If Link pulls it out, but doesn't use it, it will grow larger and more powerful. The Hammer can be used on see-saws to clear great heights. It can kill Stalfos in a single hit by shattering their bones to pieces, similarly to the Ball and Chain from Twilight Princess.
