Bamboo Disks were the primary weapon of the Matoran during the thousand-year period in which the Matoran of Metru Nui occupied Mata Nui. They were most likely based after the Kanoka disks used on Metru Nui. However, unlike Kanoka, these disks are made from Bamboo Wood, not Protodermis, and they have no special powers. Some disks had pictures of Kanohi masks inscribed onto them, although this was only for ceremonial purposes and had no significance relating to the disks' power or attributes. Generally, the Kanohi on a Matoran's disk was that of the patron Toa of their element, although Hafu used a disk with a Kanohi Hau on it. Disk-throwing championships were a popular alternative to Kolhii matches, and Hafu was believed to be a champion.
Disks were manufactured primarily in Le-Koro, although they were owned by Matoran all over the island. Matoran trained in Disk-Throwing at the Disk Range of Le-Koro, tended by the Le-Matoran Tamaru. Here, disks were used to train in the Kolhii Skill of Accuracy. In Po-Wahi, Takua found some Bamboo Disks that he used to fight Rahi on his quest to save the Turaga and find the six Toa Stones. Disk throwing contests were held, and on the way to one, Hewkii used a disk to ensnare a Nui-Jaga that was blocking the route for him and other Matoran.
Following the invention of the new form of Kolhii, Disk-throwing went slightly out of fashion, although many Matoran continued to carry disks for defense against Rahi and other tasks. Shortly before the commencement of the Kolhii Tournament on Mata Nui, Hahli used a Disk to knock the counterweight loose on a bridge which had been knocked out during a violent storm, restoring access to the rest of Ga-Koro. She also used Disks to train in Accuracy.
In Challenge of the Rahi, Hewkii threw a disk to trigger a trap against an attacking Nui-Jaga.
Six versions of the black plastic disks were released, each printed with an image of one of the Kanohi masks of the Toa Mata and the name of the Toa Mata who chiefly wore that mask. They were available in the six promotional Matoran sets released in 2001 McDonalds Happy Meals. Pulling back and releasing the Matoran set's right arm enabled them to throw the disk.
