One Piece Wiki

The Cat Claws[2] are Kuro's primary weapons. They are first seen being used against Merry,[1] and later properly introduced against the Nyaban Brothers.[3]


The Cat Claws are a pair of black furred gloves sporting a full-length katana blade at the end of each finger. They are reminiscent of claws, resulting in their name. When not in use, they are typically kept inside a duffel bag.


Due to the length and sharpness of the blades, one swing can inflict multiple aggravating wounds and cut through walls and rocks.[1][4] However, they may not be exceptionally durable, as Luffy managed to snap the right claw.[5] Kuro pushes his glasses up with his palm in order not to scratch his face with his claws, a behavior that he retains even after assuming a civilian identity.[3]

Kuro primarily uses these giant claws in conjunction with his superhuman speed to strike his opponents with such swiftness that they will not know what struck them until it is too late; he can reportedly kill 50 highly skilled assassins before they notice his presence.[3]

Though Kuro's raw speed is roughly the same as that of CP9's Soru technique[6] and long claws make him a deadly fighter, his weakness lies in his inability to see clearly while running, causing him to strike anything his claws randomly connect with, whether it be an enemy, the surroundings, or his subordinates.[4]



  • Shakushi (杓死 Shakushi?, literally meaning "Scoop Death"): Kuro's ultimate technique. A fearsome attack that utilizes Kuro's Nuki Ashi to the fullest, moving at a speed of 100 meters in 4–5 seconds,[6] allowing him to sweep a large area and kill anything his claws connect with, including his own crew. He initiates this move by swaying back and forth sideways in a fluid manner; this is necessary in order to enter the "trance" needed to perform the move. The degree to which he inflicts his attacks is so random that they range from mediocre scratches to fatal evisceration of both friend and foe alike. He moves so fast that even he does not know what he's attacking, and only stops when he becomes tired (or when someone can catch and physically stop him, as Luffy did). In the anime, this move has the side-effect of generating purple clouds of smoke that rise from the ground as Kuro moves at his topmost speed.[4] It is said that he killed many of his own crewmates in the past with this technique. In Unlimited Cruise, Kuro uses this attack to focus on his opponent with multiple strikes, rather than wreaking widespread carnage. In the 4Kids dub, this attack is called the Cat Out of the Bag Attack, and in the FUNimation dub and Viz manga, it is simply called "Out of the Bag Attack", referring to the phrase "Cat's out of the bag".
  • The name of this attack comes from the Japanese phrase "neko mo shakushi mo" (猫もしゃくしも literally meaning "even cats and rice ladles"?), which means "absolutely everything", reflected in the attack attack's indiscriminate nature. It's also a pun of the Japanese word Sakushi, which means schemer, referencing Kuro's personality.

Anime and Manga Differences

Kuro contemplating on killing Kaya in the anime

In the manga, when Kuro unsheathed the claws to strike down Merry, only the tips of the blades were shown. The anime shows the claws on his right hand entirely. Furthermore, in the anime, he contemplated on using the blood-soaked claws to kill a sleeping Kaya before deciding against it.[1]


  • These weapons are possibly based on the real life weapons, the tekagi-shuko and neko-te.
  • The Nyaban Brothers fight with similar gloves to that of their captain, albeit much shorter and with simply long nails as opposed to katana blades.
