Kirach (or something) for comment

[Cthulhu]

I'm calling this a kirach, because of the downward droop of the blade. It was sold as a firangi, but the blade doesn't look at all European to me. It went with no bids twice on ebay before I bought it, which makes me feel a little less confident in its value, but too late now.

I'd love to hear the opinion of the forum; kirach or something else? Decent item or unfortunate cash sink? Also, I'm curious if anyone has any opinions on the helical markings on the back spike. I've never seen that sort of pattern there.

These are the photos from the auction listing, which I assume the seller won't mind me using until the sword arrives.
