The air saber was a bladed weapon formed by Lewa Nuva's adaptive weapon while he was in Karda Nui.1, 2, 3, 4 Like the rest of Lewa's adaptive armor, his adaptive weapon changed shape to suit his environment, and it took this shape in response to his presence in the sky of Karda Nui.CN Lewa used the air saber to channel his elemental power of air, which was particularly powerful when battling in the sky.1 The air saber was strong and razor-sharp,1, 5, and like the rest of Lewa's adaptive armor, it was made of protosteel.6, 7, 8 This adaptive weapon was a separate object from the rest of Lewa's adaptive armor.9 It presumably took on a different form sometime after Lewa left Karda Nui.
