Hey guys! After the recent One Piece Chapters we discovered that black blades are not made but after time, they eventually become black. It has been theorised that it was the infusion of Armament Haki into the blade after many uses eventually the sword will become a black blade. However, there is another interesting theory about black blade. According to “u / yung_clout_warrior”, blades become black through the use of Conqueror’s Haki. In today’s post, we will be talking about this theory.

In One Piece World, Conqueror’s Haki is displayed differently in different instances. For example when taming an animal only a “look” is required, or at fisherman island. But in the intense instances of Conqueror’s Haki we see “black lighting” emanate from the user, for example Big Mom, Luffy vs. Doflamingo, Luffy vs. Katakuri and Luffy vs. Don Chinjao.

We know that the “black lighting” isn’t just the clash of Armament Haki or Conqueror’s Haki since the “black lighting” is emitted by Big Mom screaming which neither a clash of Armament Haki or Conqueror’s Haki takes place. Interestingly, when we see Kaido attack Luffy we see this same “black lighting” incorporated into Kaido’s club, followed by an unconscious Luffy. Therefore, it can be concluded that Kaido used Conqueror’s Haki against Luffy.

What makes this instance of Conqueror’s Haki so different compared to the other examples is by how controlled it was. In the examples above, we see the surrounding areas become damaged and weak willed people are knock out yet this do not happen when Kaido used it. Furthermore, Rayleigh explained that Conqueror’s Haki has to be controlled otherwise it will harm to those around you. So, it can be concluded that Kaido can control his Conqueror’s Haki so well that he is able to infuse it within his weapon. Also, if it is possible to use Conqueror’s Haki within a club it should be possible to infuse Conqueror’s Haki within a sword.

Relating this back to the theory, if Conqueror’s Haki is exerting your will over others and if it is possible to use Conqueror’s Haki onto a sword, then a swordsman with Conqueror’s Haki can exert their will onto their sword. A swordsman with Conqueror’s Haki doing this repeatedly with their sword, the swordsman able to cut more things that they will. A blade becomes permanently black due to the swordsman’s successive use of Conqueror’s Haki onto the sword. We have seen that a swordsman exerting their will over their sword is essential to becoming a skilled swordsman.

Conqueror’s Haki enables a user to exert their will over others. Furthermore, Conqueror’s Haki is a rare and powerful quality which is possessed by some of the most significant characters in the One Piece World. The combination of Conqueror’s Haki and swordsmanship hasn’t been explicitly stated within One Piece yet, but the rarity of a black blade and the significance of the wielders may suggest that it isn’t a mere coincidence.
