Is that what you're talking about?

It's not segmented, but it can give that impression if you're used to seeing the Chain Whip. Apparently, it's considered the most dangerous and advanced weapon of Kalari. It's called Urumi. Dig it:

Apparently, it was used in the filmi Ashoka! I haven't seen this one yet, but will make a point to, soon.

Regarding that film clip, I have no idea, but pretty sweet find!
