Khukuri with nicely carved handle

[Kmaddock]

Hi All
I just purchased the attached as part of a job lot.
Not my area of collecting but we all know how hard it is to stay focused!

It is the sharpest knife I have ever acquired with 13 inch blade and 5 inch handle
Feels perfect in the hand with perfect balance
The blade has some small forging flaws but they do not detract much, it had surface rust but this cleaned up very well.
Nicely done hollow ground blade

It has an internal tang with nothing showing on but of grip

The carving on the handle is very well executed, this leads me to believe it may be something half special.

Would anyone have any idea on age or origin.

Much appreciated as ever.
