Gold Dust

, is the name of the weapon used by the Fourth Kazekage. Due to its composition, these small particles of gold can be manipulated in a similar manner to that of the sand utilised by the One-Tailed Shukaku's jinchūriki, when used in combination with the Kazekage's Magnet Release. However, unlike his son, dark rings only appear around his eyes while the technique is in use.

In sufficient quantities, this gold dust can be fashioned into a diverse range of formations of both varying complexities and dimensions, with the most simplistic of these often employed to attack or block an enemy. When used offensively, the Kazekage tends to form dense surges that can range from narrow streams to colossal waves in size, intending to injure an opponent by violently crashing the compact and fast moving gold into them. However, when used defensively, he instead creates thick walls of the substance that are durable enough to block even Gaara's Sand Hail. More complex structures can facilitate similarly elaborate tasks, such as observing an area from afar.

In the past, this weapon was instrumental to the protection of Sunagakure during the Fourth Kazekage's tenure, by allowing him to effectively subdue the Shukaku each time the creature went berserk. This was accomplished through the integration of his gold dust with the sand that remained under the beast's control, which due to being appreciably heavier than this particular material, would vastly increase the sand's weight when combined. Consequently, this made it more difficult for the creature to manipulate and thus slowed the sand down considerably, if not nullifying its movement entirely.

Trivia

 * Gold isn't a magnetic metal like iron, nickel or cobalt. However, it is diamagnetic.
 * Gold is approximately 2.5 times denser than iron; and about 7.3 times denser than silica which is the main component of sand.
 * When Sunagakure was suffering dire economic strains, this gold dust was used as a valuable trade commodity of the village.
