The Malla has the weird cho. On my Malla, which is 22 ounces and 18" in length, it has a nice thick spine tapering to a uniform slender edge, probably a 'saber' style edge being not quite convex. The profile is shark like, with a real point, and this will fight. It is not unlike a larger version of the Yangdu Special, but with the Malla cho. This is an old style, with the tooled scabbard, and I'm not sure how it compares to HI's rendition today. I have noted the cho is less deep these days, and that's an improvement, as the cho on mine travels towards the spine and thus weakens the blade some. Still more than enough metal there to be strong, though. Come to think of it, both the Malla and Chitlangi have the two most unusual chos of the HI stable.
I've always loved the heart shape of the Chitlangi khukuri. That's enough to give you Chit Fever if nothing else. ( I had to work that phrase in. I really like Chit Fever)
But many thanks to the forumite who traded me long ago. I love my Malla.
The handle on my Chitlangi is longer, and has a real bell style end cap, that hand filling knob which reassures the user the blade is not about to fly out of one's hands. Actually, the bell end lets me use a style of swinging/chopping that is different from other khuks. You can almost 'throw' the blade yet still have it in your hand. More on that another time.
The Chit is ornamental, of course, and I like it very much. I'm not a ornamental person. Even the Sweeping lines of the Rose are a little out of my world. But the design and execution of the good looking stuff on the Chit is pleasing to me. I'll not kick the Chit out because it's too good looking.
My Chitlangi is 19" long. (not 19.5" as I falsely remembered) The difference in length from the Malla is only an inch, but I think an inch over 18" counts for a lot. For one thing, anything beyond 18" seems to swing against my leg worse. It's just harder to carry around. Gets in the way more. I think 18" is not only a useful number when you think about leverage, but also carryability.
The Malla is a wicked little blade. The Chitlangi more sweeping to my eye. I think the Malla is a little faster, and it may be that is true in a general comparison as well, but I don't know. It would be good for others to weigh in and tell us. That's why we have a forum, after all- we get to learn.
Both could work. I used the Chitlangi to cut down a tree when I first got it, as a test. I think the tree was about 8" in diameter. The Malla seems more of a fighter to me.
