Magical Sword

In The Legend of Zelda, the Magical Sword is the most powerful of the three swords Link can use. It is more powerful than the Wooden Sword or the White Sword. It is found under a grave in the cemetery. It is assumed that this is the sword wielded in The Adventure of Link as well.

There is a some debate as to whether or not the Magic Sword is in truth the Master Sword. Although in the Twilight Princess, a similar looking sword is wielded by the Hero's Spirit, while Link has the Master Sword.

Soulcalibur II
In the fighting game Soulcalibur II Link made a special guest appearance as a fighter. One of his weapons was the Magical Sword, and although it looks different from the original images of the magical sword (having a purple hilt like the Master Sword and the Triforce on its hilt) it still bears its name. The Magic Sword is capable of piercing defences, but the Magic Shield it is paired with apparently hasn't held up as well, and is slightly weak to impact.
