Yemeni Wahabi Gile or Qolxad?

[kronckew]

Known there as a Qolxad (?) (wiki link)

metal work looks like tarnished silver or brass, double fullers. seen service & has appropriate dings. listed as 19c.

Vendors description:
Wahabite jambiya, mid-19th century, nomadic Banai Quran tribes,
used also by the Shar and Malik warriors of the desert dunes.
(The weapon is also referred to as a “Dharia” or sometimes a “Malsa”)
The knife is 50 cm (2 ft.), blade is about 36 cm long (14 in.)

Looks like one a step up from bluelander's one HERE

And a step down from the one he mentioned which is HERE

Have not seen the Yemeni attribution before, is this accurate? how can we tell whether it's Yemeni/Somali/Ethiopian?

I see Somalis wear them on their right side, drawing it must be interesting, reminiscent of a khukuri...

Thanks for any comments.
