Speculations Break Week: Black Blades

#23
Black blades, one of the last mysteries of One Piece.

We are this far in One Piece and we still don't know how black blades are created. Oda has has only given us a few hints. We have learned about ACoA haki, ACoO, and ACoC, DF awakening, and how DF were created (somewhat). Yet, we still know very little about black blades.

That says a lot about black blades. How difficult they are to create and how strong one becomes by forging a black blade.

I think black blades are the true Pinnacle of swordsmanship or at least part of it. We are told the Pinnacle of swordsmanship is the power to cut what the swordsman wishes to cut. But if black blades are supposed to be unbreakable how can they be cut? An unmovable object and unstoppable force can't both exist in the same universe. One has to give and I believe a black blade can stop the power to cut anything. At least for now.

I believe Zoro will obtain the power to cut or break a black blade against Mihawk. A feat never before achieved. More on that at another time.

I can see a black blade being the equivalent to DF awakening for swordsman in a sense. I believe a swordsman will grow in multiple ways from forging a black blade. I've talked about that another thread here's my post:

It's not just about possessing a black blade. The greatest benefit will come from creating (forging) one.

First, there are known benefits to having a black blade regardless how it is obtained.
- greater defensive power. Black blades are unbreakable so possessing one means the user will never have to worry about their sword breaking so their defensive power will increase.
- greater offensive power. Black blades increases AP because of the stronger blade. When Zoro first used shisui his attacks from shisui were stronger than his other swords attacks.
- better haki preservation. Possessing a black blade is like always coating your sword with a strong blackened CoA haki without needing to actually do that. When haki is needed to create stronger offensive or defensive techniques the user won't need to use as much. Of course, black blades don't actually contain haki so haki will still be needed to counter DF power.

Possible benefits to possessing a black blade.
- I believe black blades are heavy. Creating a black blade increases the weapons weight. Zoro stated Shisui was heavy compared to his other two swords. A heavy blade means the attack will have more weight. That increase in weight will increase the attack power. The user will grow physically stronger from needing to train to control the heavier sword.
- I believe black blades don't possess cursed/dangerous power. Creating a black blade will remove the curse/dangerous power the sword posseses. I don't have anything to support that but I do find it interesting the only difficulty Zoro had using shisui had to do with possessing a black blade, nothing about shisui.

Let's look at the possible benefits one can obtain from creating (forging) a black blade.

At this time nobody knows how black blades are created but the manga has given us some insight so we have some information to work with.

- largest/strongest CoA haki amount and the best CoA haki control in the manga or near it. There is enough information to confirm blackened haki is needed to create a black blade. But just possessing that isn't enough to create one. Since Zoro has mastered enma he has started to create a green aura around his swords when he's using KoH techniques. We have never seen that before from any character. I believe that is Zoro adding an incredible large amount of controlled blackened haki to his swords and that is the first step to creating a black blade.

- incredible powerful CoC haki and control. We know just to fully master a sword the user must bend the sword to their will. If you create a black blade you aren't just bending it to your will you are changing the sword. That can only be possible if you can completely dominate the sword.

- I'm sure I'm missing one or two more things needed to create black blade.

Of course, a black blade creator will receive a huge increase in CoC strength. Having the skills/power to create a black blade and creating one will make the user stronger. As they grow stronger so will their CoC strength. Similar to what happened to Luffy when he obtained awakening.

At this time I think to forge a black blade the user must have the best/strongest/top tier CoA and CoC haki.

CoA haki gives black blades their color and hardness. Mihawk hinted during Dressrosa any sword can become a black blade. He said if Zoro's swords would have been black blades they wouldn't have broke against him. That tells us black blades are so strong not even Mihawk can break or cut them.


CoC haki is needed to permanently change the blade. If a swordsman must bend a sword to their will to master it and CoC is not needed to master the weapon. Than more must be needed to permanently change a blade since that is beyond mastering the blade. I can only see that being achieved with the some of the strongest CoC haki in One Piece.


I think Zoro has started the process to forging a black blade. The fox told use black blade are forged in battle.


I find it interesting that the manga used the term "forge". Forging is the process of heating and hammering the metal. Zoro can put his swords in a state were they appear to be heated by using overwhelming amounts of CoA haki. Plus he can add CoC to it and fight with it in battle.


It's no coincidence that Zoro created KoH that gives them all three, CoA, CoC and battle experience.

I know, some might be thinking if overwhelming amounts of CoA haki and CoC haki are the two main components needed to forge black blades why don't we see more top tier swordsman ot weapon users with black blades. Part of that reason is because it's too risky. Not only do I believe Zoro will need to increase his CoA haki out even further. Pound for pound, ACoC is a greater buff than CoA barrier when it comes to increasing offensive power. Using up all of your CoA can possibly kill you. Why use such large amounts of CoA haki when ACoC haki can be used to achieve the same thing, increase in offensive power, without the risk. Not everyone has CoC so running out of it shouldn't kill you.

I still feel there's some things missing to create a black blade. I'm not sure if the highest/vest CoO is
also needed.
