I'll second the Chitlangi. 21" Chit is about the ultimate fighting kukuri.

I would agree as much as for the Chitlangi's hitting power vs. a Sirupati of similar size while not being as bulky as a 20" AK.... but I've compared Chitlangi vs Sirupati and the Sirupati wins as far as speed, agility, and quickness of recovery go. The Chitlangi is my favorite khukuri because of its versatility; it's a good "fighter" AND a good "worker".
On the other hand, the guys in Nepal made a special Chitlangi to my specs with a chiruwha handle. The extra steel in the handle did add a lot of weight to it, but all the extra weight changed the balance considerably - just as I theorized - and the result was a big (23.75") and heavy Chitlangi, that handles very well for its size & weight, making it a nearly indestructible tool and a ferocious weapon at the same time.
I'd say a 21" Chitlangi with a chiruwha handle would give one the benefit of a khukuri which hits harder and bites deeper than a Sirupati of similar size while having handling ability more like the Sirupati.
As for my comparisons, I only have two Sirupati's - one by Vim and one by Bura - and the 20.25" Bura made is an extremely quick and well-balanced blade. I have a small collection of Chitlangis to compare them to and the Bura Sirupati is faster than them all... but the Chitlangis win as far as cleaving power goes.
Which again is why I like Chitlangis - they have some of the AngKhola's power combined with some of the Sirupati's agility and speed.
There's always a trade-off. What's perfect? That a matter of personal taste.
In my collection, the 20.25" Sirupati is the one I'd consider a true fighting khukuri, but if civilization collapsed my pick would be Sher's magnificent 21.5" Chitlangi. There's just something special about that one.
