North African dagger for identification

[ariel]

Well, to each his own. I also ordered Steel and Magic, even though it is not my area of interest.
But these days and for quite some time I am mostly collecting good books. There are so many things I learn from them!

One thing I have learned from Eric's book is that nobody, but nobody, in Morocco calls a Koummya "koummya". It is a Khanjar.
And that shorted some neurons deep in the amphibious part of the brain....:-)

What always puzzled me is the peculiar, practically unique, way of sharpening the edges of Koummya. It is double edged, but the convex side is sharpened only on the distal ~ 1/3 , whereas the concave side has 1/2-3/4 of it sharpened.

There are not very frequent examples of Persian khanjars with a very similar construction.
Anybody has an opinion whether it is just parallel development or a borrowed idea, and whether the local Moroccan moniker reflects it?
