Blade-Blade Fruit

The Blade-Blade Fruit (ケンケン実, Ken Ken Mi) is a Paramythia-type Cursed Fruit that turns the user's body into steel and allows the user to turn any part of their body into a steel blade to attack opponents with, making the user a Fullbody Bladed Human (全身刃物人間, Zenshin Hamono Ningen). The word "Ken" (ケン) is deraived from "剣" (ken), a japanese word for blade. It was eaten by Daz Bonez, also known by his Baroque Works alias Mr. 1.

The fruit's powers were first seen being used by Bones to slice a wall he was about to hit, after he was kicked by Mr. 2. The fruit's powers were fully revealed when Bones and Zoro began to battle.

Strengths and WeaknessesEdit


The major strength of the fruit, as demonstrated by Daz Bonez, is that its user can create strong blades from any part of their body. The user's body also has become completely steel in composition, and is immune to normal slashing attacks.

He also seems to have the ability to cut through objects without the need to physically touch them; this is likely a similar principle to air-based slashes used by various swordsmen. This is shown in his Atomic Dash and Tower Crusher attacks, as well as an unnamed attack he used when he first demonstrated his ability by attacking Nami.


While immune to physical attacks while the user's body becomes completely steel, any specialized attack capable of slashing through steel is capable of slashing the user's flesh.

Other than that, the user is also affected by the standard Cursed Fruit weakness.


The fruit's bestowed powers, as used by Bones, have been used primarily for combat. He uses them both for defense and offense. He was shown to have turned his leg and foot into a big blade to attack the opponent, clashing against Zolo's swords. He can also quickly spin these leg blades while doing a hand stand (similar to Sanji's Rolling Dish) to slice nearby opponents, creating a small but sharp and powerful hurricane, as he did so to defeat the Navy on board of the battleship they fought on.
