If you want a better look at them then look at this clip (58 seconds in)
Thunderdome clip
Its one of the clips thats always in trailers for MM3, the mohawk henchman blowing the bits of feathers away when Max gives him a haircut with the sawn-off got a huge laugh in the cinema when I saw it back in the day.
As for your question, the blades are like long Kerambits on fine chains/swivels.
Imagine Freddy's claws detached and hung.
Interesting but more form than function.
