The fang blades were a pair of bladed weapons that served as Matau's Toa tools when he was a Toa Hordika.1, 2, 3, 4, 5, 6 Although Matau lacked elemental powers as a Toa Hordika, he could use his fang blades to charge his elemental air Rhotuka spinner, which could significantly increase the strength of its effects.1, 2, 3, 4, 6 In order to do this, Matau needed to hold up his fang blades, launch a Rhotuka spinner from his back, and mentally will it to hover in place in between his fang blades while they charged the spinner, before releasing it again. It took only a couple of seconds to charge a spinner up significantly.7 Matau could not charge anything else with his fang blades other than his own Rhotuka spinners.8, 9 The fang blades could also slice through even the strongest Visorak webs1, 2, 3, 4, 6, as well as cables1, 6.
Matau's aero slicers mutated into the fang blades when he was mutated into a Toa Hordika. When Keetongu cured Matau, the fang blades turned back into the aero slicers.CN
