That's exactly why I've always wanted a kukri, since I was tiny kid. They looked so natural to me.
I had a lousy tourist wall hanger kukri that my folks brought back from Turkey. But i chopped stuff with it anyway. So when i started looking for a new camp knife and hatchet, I thought about how handy that old kukri design was. And my search landed me here also.
The power of a knife is in the cut, and the curve makes the cut as you said. I think you got a good one. Your WW2 - 17.5" at 23 oz, is a very good ratio. Get some epoxy so you can fix the handle crack when you get it. You shouldn't have any further problem out of the horn handle after the epoxy sets.
