Well this is not going to be "valuable" in the sense of retiring early off of it...paying off one's mortgage kind of deal. BUT...we are all, sort of collectively coming to understand (in the course of this fascinating thread) that you
probably have something quite interesting, probably old, probably real, and probably worth something to a collector.
We've also learned that there is a Kukri tradition in Afghanistan, apparently transplanted there by Gurkha regiments over the years and the Afghans, no strangers to the use of arms, recognized the value of the pattern...and started making them.
In addition we've learned that one thing that distinguishes the Afghan kukri is that nut on the pommel/bell. I am not seeing the karda and chakma included in these very simple sheaths either. They all seem to have that very graceful leaf shape and seem to be what we'd call "full flat grind" in modern knife terminology. Modern and/or Tourist kukris have much thicker blades at the spine and have a wide bevel.
JD, we all appreciate your service to our country in what has been a troubled land for centuries. Glad you're back. We also appreciate bringing this really neat old knife forward for all of us to be excited about. Some of us have lives, some us don't (like me

) so stuff like this is gold.
