The Air Katana were the tools of Toa Nuva Lewa, which allowed him to glide through the air. He received them after emerging from the Energized Protodermis in the lair of the Bahrag. On Voya Nui, Reidak snapped one of Lewa's Air Katana in two, but it was later replaced by Velika. Lewa has replaced his Katana with an Air Saber and a Midak Skyblaster when he received Adaptive Armor.
The two Air Katanas were included with the Toa Nuva Lewa set. On his Canister, it shows that Lewa can hold both Air Katana in one hand, like Tahu or Kopaka. However, he was never seen doing this. The Air Katana could be placed behind Lewa to make glider wings. Set-wise, the Air Katanas were seen in many other sets as tools of different names and abilities.
