Zoro challenging the Kitetsu curse against his luck. Sandai kitetsu is most regarded for its great sharpness, making it far easier for slicing things, as highlighted when Zoro decided to test his luck against its curse, with its previous owner, Ipponmatsu declared it could cut off his arm.
It was only destroyed due to rusting power of Shu's Sabi Sabi no Mi. When used by Zoro, Yubashiri was one of the three swords for his Three Sword Style style and it was typically used along with Sandai Kitetsu in his Two Sword Style techniques. When the sword was destroyed, Zoro replaced it with Shusui.
Zoro has used 6 different main swords and 4 temporary swords throughout the One Piece anime. Does Zoro have 3 or 4 swords? Zoro usually carries three swords with him to perform the three-sword style anytime. So currently, he has the Wado Ichimonji, Kitetsu III, and Enma with him.
Along with Wado Ichimonji and Sandai Kitetsu, Shusui once again completes Zoro's three swords. However, it's traded for Zoro's next sword.
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.
Demon Asura Zoro
Another popular One Piece fan theory is that Zoro's left eye was closed to help maintain control over his Asura powers. The crux of this theory is that Zoro is “possessed” by the Asura demon as a result of his use of cursed swords throughout One Piece.
Unfortunately, it's yet unknown if Zoro can use his left eye or not in One Piece. The Straw Hat Swordsman received the injury during the timeskip, and has yet to discuss the issue with his crewmates and captain.
Enma is the strongest sword possessed by Zoro of the Straw Hat Pirates right now.
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. It's become both a piece of prized equipment and a reminder of their promise to become the strongest swordsman.
Wado Ichimonji has been Zoro's most iconic weapon since day one. Another one of the 21 Great Grade Meito swords, the sword has become synonymous with the Straw Hat swordsman, coming in handy throughout his many difficult battles. Like his tow unnamed katanas, Wado Ichimonji was crafted by Shimotsuki Kozaburo.
Actually not just 1, he can eat 3 devil fruits. Yes.
The Wado Ichimonji is a sword of great personal importance to Roronoa Zoro, and it was once Kuina and her family's sword. It is also one of the 21 O Wazamono grade swords.
When a blade is imbued with COA, it becomes black. However, a black blade is one that is permanently imbued with Haki, and remains black even when the owner isn't there or Haki isn't being channelled into it.
In the anime, Luffy managed to use it to cleanly cut through multiple swords with great ease despite his lack of skills. Like all of the swords crafted by members of the Kitetsu school, this one is said to be cursed and will bring a horrible death to all of its owners.
Because it's a national treasure stolen from Wano and the circumstances surrounding Zoro's fight with Ryuma are strange. Wano Country owned the sword after Ryuma's death.
It was formerly wielded by Kozuki Oden and was passed on to Kozuki Hiyori, his daughter, after his death. This sword was then given to Roronoa Zoro in exchange for Shusui. While the sword is certainly not a Supreme Grade sword yet, it also hasn't blackened.
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.
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.
Just as Luffy powered up by creating Gear Second and Gear Third to take down Lucci, and Sanji tapped into the hellish flames of Diable Jambe, Zoro tapped into the power of the demon spirit Asura.
Zoro set out on his journey to becoming the greatest swordsman in the world by defeating Dracule Mihawk, the man who currently sits on the stone. Over the years, he has come a long way and become one of the strongest pirates on the seas. Zoro has attained terrific strength, but he does not rely on a Devil Fruit at all.

Luffy Gave Himself the Stitch Scar Under His Left Eye
In order to prove his courage to the pirates, Luffy took a knife and stabbed himself below the left eye. The act resulted in a scar that certainly made him look tough as a pirate. While there was some humor in this, it proved too brutal for the anime.
Zoro was the first person who accepted Luffy's invitation and joined the latter on his journey to become the Pirate King. Zoro is a very powerful fighter and he possesses all three types of Haki. Zoro was able to use Conqueror's Haki unknowingly against Kaido.
