(In Turok 2: Seeds of Evil and Turok 3: Shadow of Oblivion) A disc with sharp, rotating blades surrounding the edge. The user tosses the weapon and the blades start to rotate at a high speed so as to tear through the flesh and bone of a target. The Razor Wind then returns to the user like a boomerang. The Razor Wind is often known to decapitate or severe the limbs of it's targets.
Holy crap! That Razor Wind just cut his arm clean off!
