Sand Binding Coffin

With his ability to control sand, Gaara encases his opponents in a large amount of the special chakra-infused sand kept inside his gourd, immobilizing them. It can be used to suffocate an opponent or in preparation for a deadlier technique, the Sand Waterfall Funeral. This appears to be Gaara's signature technique.

Trivia
the sand coffon is a sand encloser so stron the it has the powere to rip off a body part (just like what happend to Dedicada) tink thats how you spell it ! :)
 * Using a pun common to Gaara and his jutsu, is pronounced the same as the Japanese word for.
