Shukaku no Hoko is a Ninjutsu technique said to be Gaara's Saikou Zettai Kougeki (Supreme Absolute Attack). Gaara collects extremely solid minerals and mixes them into his sand using pressure from his chakra. This creates a very strong and hard Shukaku-like halberd which he can then throw. The strength of the material allows it to penetrate a very strong defense.
