Thanks for your comment Ibrahiim. So we definately have an Omani Khanjar.
I believe that Yemeni makers have had access to blade making machinery, and that blades of this sort were occasionly found on their work. So the possibility exists that this blade originated there.
As to putting new bits unnecessarily on older pieces, I think you by now must know my feeling about this. Great idea if thats what you deal in, but again it's creating something which is NOT original.
