Lotfy, thank you very much for sharing, I had never even considered the possibility of wootz dharia blades. As rare as such blades would be, there are probably some in collections that simply have not been polished and etched. Back in 2009 Rick Stroud published a presentation for the Timonium seminar of some wootz blades on swords where you do not really expect wootz, including a longer Omani saif on slide #4:

In your opinion, is this another example of Yemeni wootz?
