Chakra Enhanced Triple-Bladed Claw

Chakra Enhanced Triple-Bladed Claw (チャクラはトリプル枚羽根の爪を強化, Chakura wa toripuru mai hane no tsume o kyōka) is used by Sora and his father, Kazuma. It is a claw with three blades which can be enhanced with the user's chakra, even the user's chakra nature. It has the same effect as Asuma Sarutobi's trench knives.

The original weapon that Sora wielded was broken in a battle with Kazuma. But due to an act of kindness from Asuma, it was later reforged with the same special material that was used to make his trench knives. During Naruto's confrontation with the four-tailed Sora, he uses a broken piece of the claw to injure himself in an attempt to prevent his own transformation.
