|Function||Melee combat, transportation|
The Fire Blades were powered by the element of Fire. They could be used as a pair of swords or be combined together to create a Lavaboard.
Tahu used his Fire Blades to defeat several Skull Spiders after he crashed in the Region of Fire. He later used the pair as a surfboard to cross a pool of lava and retrieve his Golden Mask of Fire. After doing so, he used it to rise up to the Protector of Fire, and split the Lava Board apart, forming his Fire Blades. Using these blades, he saved the Protector and defeated many Skull Spiders.
Later, when he and the Toa encountered the Lord of Skull Spiders, Tahu used them to engage in combat with him, only for the Lord of Skull Spiders to knock them away. After the latter's demise, Tahu reclaimed his Fire Blades.
The Fire Blades were released with the Tahu set in early 2015. They consisted of four parts.
