Hi Marius,
This link will be of help I think. Also if you use the Forum Search facility you will find other references to these daggers/knives/short swords.....what ever you wish to call them. The one you have is a nice example though I suspect not too old and as Lofty has suggested, is of Yemeni origin rather than Hejazi.
