Roronoa Zoro is the combatant of the Straw Hat Pirates and a powerful swordsman. Zoro aims to become the strongest swordsman in the entire One Piece world.
Using his Three-Sword Style, Zoro has toppled quite a bunch of powerful enemies in the series so far and acquired some fine blades as his journey has continued,
some of which are known to hold legendary status in the One Piece world. These swords are so strong and valuable that they even come with special names.
Sandai Kitetsu is one of the Wazamono blade swords, also known as Grade Swords.it was first introduced to the fans during the Logue Town arc of the series
where Zoro picked it up from a barrel after sensing sinister energy coming from it. Sandai Kitetsu belongs to the family of the Kitetsu swords and thus, is a Cursed Sword.
This sword is extremely difficult to control due to its thirst for blood, however, what's even more dangerous is that it brings a terrible death upon whoever wields it.
Yubashiri is another blade that Roronoa Zoro got his hands on during the Logue Town arc of the series. After displaying his courage and testing his luck against the curse of Sandai Kitetsu,
Yubashiri was a fine blade, however, Zoro lost it during the Enies Lobby arc of One Piece when he faced Shu, a man with the powers of the Rust Rust Fruit.
Wado Ichimonji is the first named sword that Roronoa Zoro carried in One Piece. It was forged by Shimotsuki Kozaburou, a person from Wano Country.
This sword once belonged to Koushiro, the dojo master of Zoro from Shimotsuki village, and was meant to be inherited by Kuina, his daughter.
This sword belongs to the group of 21 O Wazamono grade swords which are only exceeded by the 12 Saijo O Wazamono grade swords.
Another one of the 21 O Wazamono grade swords, Shusui was once the blade of the "Sword God" Shimotsuki Ryuma.
Using this very blade, Ryuma was able to slice off a dragon's head in Wano Country, and that's known to be just one of the many great things that he's accomplished over the years.
Enma is an incredibly powerful sword that also belongs to the class of 21 O Wazamono grade swords.
It was first wielded by Kozuki Oden, the Daimyo of Wano Country's Kuri region, alongside another blade of the same class, known as Ame no Habakiri.
Enma has a purple hilt and scabbard, which is rather similar to Nidai Kitetsu in some ways. In terms of power, it is one of the finest blades to have ever been created, but also one of the hardest to control.
