Sprite model? How did they do this?

Are you sure the razor parts are facing you from every angle? Because it doesn’t make sense to have that effect for this kind of wire. To me it looks like masked material on a spiral plane, and normal map is helping with that “3d” illusion.

I agree it may not make sense, but this effect may still have been implemented to reduce the artifact of aliasing. Sometimes you can even do things like increase the thickness slightly with distance to decrease aliasing etc.
