Lokomo Sword

The Lokomo Sword is a weapon in Spirit Tracks.

Location
It is said by Anjean that this sword was given to the Lokomo as a gift, as it was once used by the Spirits of Good who used it to defeat many evil creatures during its lifetime. The Lokomo Sword is given to Link by Anjean inside the Spirit Train after the young hero and Princess Zelda retrieve the Bow of Light from the Sand Temple. Although only spirits had wielded the sword before, Anjean trusts the Lokomo Sword to Link, saying that he is the one who is meant to wield it.

Uses
The sword can harm Phantoms without the need of Tears of Light, since it's already infused with sacred energy. Moreover, the Lokomo Sword also possesses the innate ability to harm Phantoms by striking them in the back; however, unlike the Phantom Sword from Phantom Hourglass, it does not kill them. Instead, it stuns the Phantoms long enough for Princess Zelda to possess its body.

In the final battle against Malladus, Link, with the help of Princess Zelda, thrusts the Lokomo Sword into Malladus's forehead, defeating the Demon King once and for all.

Trivia

 * The Lokomo Sword's hilt is specifically shaped like the symbol of the Spirits of Good.
 * The Lokomo Sword resembles the Master Sword in many ways. Also, in the cutscene where Link tests his new sword, he uses the same attacks from many other of the 3D The Legend of Zelda games. There are no sources confirming if the Lokomo Sword is the actual Master Sword, as it possesses many of the qualities of it, like the power to destroy evil creatures.
