Magic Hammer

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

A Link to the Past
In The Legend of Zelda: 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 Hardhat Beetles. 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 The Legend of Zelda: 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.
