After wrapping an opponent with sand with either Sand Binding Coffin or Sand Drizzle, Katashi will cause the sand to implode and crush whatever is within it. According to Gaara, when used to kill a person, the death is so quick that there isn't even time for the victim to feel any pain. The pressure also produces a sizeable fountain of blood. Gaara can control the pressure used in the attack, which allows him to either break bones or completely liquefy an opponent.
