Air Katana

The Air Katana were the tools of Toa Nuva Lewa, which channeled his Air elemental energy. They could also double as "wings", allowing Lewa to glide on air currents. He received them after emerging from the Energized Protodermis in the lair of the Bahrag. On Voya Nui, the Piraka Reidak snapped one of Lewa's Air Katana in two, but it was later replaced by Velika.
