Sandai Kitetsu

The Saidai Kitetsu is a Wazamono Grade Swords, a "Sharp Sword". Like all of its predeceasing Kitetsu swords, this one is said to be cursed.

Roronoa Zoro found the sword in a barrel of cheap katanas in a shop at Loguetown. When the owner first saw it he wasn't going to allow Zoro to buy it, telling him of the curse. Zoro liked the concept and decided to test his luck against the curse. He threw it into the air and held out his arm willing to let it cut him. Zoro's luck won and the blade circled neatly around his arm. The shop owner gave Zoro both Sandai Kitetsu and Yubashiri for his skill and luck.

Abilities
The Saidai Kitetsu is has a sharp edge, making it easier to use for cutting. However, Zoro has commented that the sword appears to have a mind of its own, making it a "problem child".

Like all of the swords crafted by Kitetsu, this one is said to be cursed, and will bring a horrible death to all of its owners.

This sword, when given to Zoro, is used as one of his three swords for his Three Swords Style.
