Anyone here own or have any experience with Jambiyas? I have always been interested in middle eastern blades and I am interested in any info I can find on them....
I live in Dubai, United Arab Emirates, which has borders with Oman (the most famous worldwide for Jambiyas) and Iam a collector of all types of Jambiyas

I would be glad to give you any information you would like.
Brief history
the Jambiya (or Janbiya) form of dagger originated in the Arabian Peninsula, likely in Oman and Yemen. These forms spread geographically in parallel with the Islamic expansion and trade routes that arab muslims followed.
“some forms of this back-curving dagger exists wherever Muslim people have settled.” , George C. Stone.
Archaeological studies in the region have traced the Janbiya’s origins as early as 6000 years back, where men of early civilizations that once dominated the region are shown with Janbiyas wrapped around their waists in ancient manuscripts & drawings, among which is the Kingdom of Sheba that was once ruled by the widely celebrated queen of Sheba (pronounced as the kingdom of “Sabaa” in Arabic) which modern evidence tends towards it’s existence in Yemen in southern Arabia.
Early Janbiya’s hilts were made mainly out of a Rhino’s horn & this tradition continued till today, where the most prestigious & high priced Janbiyas are made out of the same material.
Types
Janbiyas are divided into Two major categories, which in turn branch into several sub-categories, as follows (in brief) :
1) Azizi - Saifani, Zaraaf, Asa’adi, Basali.
Azizi types are the most prestigious & expensive ones, which are usually only owned & worn by the rich & highly-ranked men in society. It is the hilt which distinguishes the Azizi types, which is carved from the Rhinoceros horn, featuring a very magnificent look & colour, with the Saifani being the most prestigious of all Janbiyas, and of course the most expensive one, with prices
I have a diverse collection of Jambiyas, such as the one below.
