Ok, i need to explain this because it seems to fly over everyone's head..
To throw a Hakified Object(or any matter) detached completely from one's user is very different than to hold an Hakified
Object..
You can not imbue Haki in a knife, and while holding it have the intent to simply throw that same knife expecting for the
imbued Haki to remain in said knife.. That's not how it works generally in One Piece..
The confusion is due to the Special Class of Weapon, Swords called Meito's where those can transmit Haki to Air Slashes and such..
Normal Weapons can not retain Haki to an object that is not connected to the Haki source, or person..
It's time people understand that Famed Blades have Haki related abilties that random Blades do not..
This notion is identical for Devil Fruits that the user can produce and control a substance, they can not throw Hakified matter
that is separate from their body and keep that Hakified matter permanently imbued..
A logia or Paramecia can not control their ability if it is detached from their body, unless they have awakened their
powers.. Likewise for Haki in Devil Fruit abilties outside of the user's touch and reach, a mixed technique of CoA
and CoC is required..
Doflmingo - Bullet Strings
Katakuri - Burning Mochi
BoA - Pistol Kiss
Cracker - Biscuit Soldiers
Ace - Flame Spears
This can be seen with Ace when he solidified his Flames as Fire Spears against Blackbeard.. It's the equivalent of
the Kuja Arrows.. Ace's Fire abilities do not have the properties of Great Grade Blades, he can not just flow CoA in them and
trust they will hold the metal like features that Haki provide..
Ace's Flame Spears needed to be CoA infused with CoC diffusion.. It's not an attack that comes from him mastering his
Devil Fruit powers.. He's creating new technique by combining his Fire Powers with Haki..
And CoA + CoC has been shown in the series to be diffused in tandem before..
Black Colored CoA Lightning Sparks diffused Along side Invisible Circular CoC waves, colored or not..
- The Kuja Arrows and Devil Fruits Projectiles need CoA + CoC techniques to be '' permanently '' Hakified..
- Famous Blades don't need CoC to create '' permanently '' CoA Hakified techniques..
