Hydro Blades

The Hydro Blades were Nokama's Toa Tools as a Toa Metru. She used them to channel her Water Element. The tools also helped her to swim through the water more quickly.

When Nokama was mutated into a Toa Hordika, The Hyrdo Blades were transformed into Fin Barbs, but the mutation was reversed. They were lost when Nokama tranformed into a Turaga. The blades can also deflect attacks by spinning them, as seen in BIONICLE 2: Legends of Metru Nui when Nokama deflects Krekka's kanoka blast.
