One of my kukris is very similar to Valjun's in the presence of a large, flared pommel, cross-hatching at both the (brass) bolster and mid-grip (though the grip on my example is made of is horn), similarly slender blade, and most importantly, in the styling of the closed, heart-shaped cho (which is more-or-less an exact match to Valjun's).
But a 20-inch blade?
I thought my own example was large, but it falls far short of that monster!
While it is the youngest of my kukri brood, I like it immensely for the large and long double fullered blade, which is signed in Devanagari and monogrammed in Latin alphabet at the choil. Poorly balanced as a weapon IMO, but distinct among my kukris.
My understanding is these come from Chitlange, in Nepal. A couple of the Nepalese production houses still offer this style kukri (click
here) - and it seems they are produced with an aluminum handle and brass bolster. A quick search for "Chitlange kukri" will turn up other examples. While the cho is not an exact match on these contemporary examples, it is IMHO similar in that it is closed off... I also agree with others and think the example shown here has a little age.
