What is Zoro's weakest sword? Out of the swords he currently owns, the Sandai Kitetsu is the weakest blade in his arsenal.
The Wado Ichimonji is a sword of great personal importance to Roronoa Zoro. It was forged by Shimotsuki Kozaburo and was once a prized heirloom of his family. It is also one of the 21 Great Grade swords. After the death of its previous owner, Kuina, Zoro asked for it from her father, who then gave the sword to him.
Enma. Enma is also one of the 21 Great Grade swords (and one of the strongest) presently in Zoro's possession in One Piece. Prior to him, it was possessed by the legendary Kozuki Oden, who even used the Enma to slay Kaido. It is the only sword along with Ame no Habakiri, which has managed to leave a scar on Kaido.
As one of the 50 Skillful Grade Swords, Yubashiri was a rare and reliable weapon that served Zoro's unique fighting style well. It was destroyed during Zoro's fight with Shu on Enies Lobby, and was later left alongside the Rumbar Pirates' gravesite on Thriller Bark.
Zoro has been wielding a sword since time immemorial, and he has owned a fair share of them. The strongest of these swords are the Wado Ichimonji, Shusui, and Enma. Wado Ichimonji is Zoro's most treasured weapon as it was been given to him by his master after his childhood friend and greatest rival's untimely death.
Being of the lowest grade of the three swords, Sandai Kitetsu is the weakest of all the Kitetsu swords. Its name also indicates it was the last of the three to be made. The panel of Zoro keeping Sandai Kitetsu in the manga is extremely similar to that of Zoro keeping Enma.
6 One Of The Gorosei, Wielder Of The Shodai Kitetsu
It is also believed that they bring a terrible death to their owners in most cases, making them very dangerous. Although not confirmed yet, it is very easy to tell that the Shodai Kitetsu is wielded by none other than the bald Gorosei of the World Government.
Either a) by the same logic Shusui is technically a grade weaker than Enma, Zoro would still have a weaker blade in Enma than Mihawk's Yoru and WB's Murakumogiri, both blackened Saijo O Wazamono swords, which should be stronger than blackening an O Wazamono sword like Enma.
Nami's Conqueror's Haki
Once awakened to it, Haki can be manifested as the Color of Observation and the Color of Armament. The Color of Observation grants a certain sixth sense to the user and allows them to sense things like incoming danger, power levels, intent, and emotions, among many other things.
Later, in the fight against King, Zoro used Conqueror's Haki to tame Enma completely. Eventually, Zoro managed to coat all his swords in what appears to be the advanced form of Conqueror's Haki, making him one of the strongest swordsmen in the story now.
In its initial depictions, in the A-ra-shi: Reborn video, its tsuka is black, and its hamon is golden. As seen in the opening "DREAMIN' ON", Enma's anime color scheme is a violet tsuka, as well as a violet sheath.
Wado Ichimonji
The legendary Wado Ichimonji has been part of Zoro's sword collection since day one. It belongs to the 21 Great Grade Meito (21 Great Grade Swords). This sword was previously supposed to be passed down to Zoro's childhood friend Kuina, a girl who defeated him several times at the dojo.
Crafted by none other than the legendary swordsmith Shimotsuki Kozaburou, Enma is one of the 21 O Wazamono grade swords to exist in the world of One Piece. Kozaburou forged his sword when in Wano and to the day of his death, he remembered this blade as his greatest creation.
Dressrosa Arc
After he saw it, Kin'emon became determined to challenge Zoro so the sword could be returned to Wano Country. While at a restaurant in Acacia, Shusui was stolen by a dwarf named Wicca. Zoro caught the dwarf and reclaimed his sword.
Dracule Mihawk is Zoro's biggest rival, being the man who holds the title of the World's Strongest Swordsman. Mihawk is extremely skilled with the blade and his swordplay is described as very aesthetic.
Yubashiri is one of the Ryo Wazamono grade swords, which makes it one of the best blades that Zoro has ever handled.
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.
On his journey to become the greatest swordsman (topped only by his mentor, Dracule Mihawk), Zoro has mastered multiple sword/blade-styles; from the three-sword (Santoryu), to both two-sword (Nitoryu) and one-sword (Ittoryu).
Enma is the strongest blade that Zoro owns at the moment. It's one of the 21 Great Grade swords, with the potential to become as strong as one of the twelve Legendary Grade swords. Zoro accepts the challenge and takes Enma, hoping to turn it into a black blade.
Monkey D. Luffy has mastered all three types of haki, including Kenbunshoku Haki (Observation Haki), Busoshoku Haki (Armament Haki), and Haoshoku Haki (Conqueror's Haki). He can even use several subforms of the hakis, which makes him one of the most powerful haki users in the One Piece world.
5 Armament Haki Subtype 4: Internal Destruction
The rarest subtype of Armament Haki, known as Internal Destruction, has only been demonstrated by two characters — Monkey D. Luffy and his mentor, Silvers Rayleigh.
Locations: Loguetown. God Valley. Skypiea (Upper Yard)
In the manga, it showed he lost it by throwing the little blade of Mihawk, like he did for the cursed sword, but he wasn't ready for even the tiny little knife and he loses his eye.
