A couple pics of an example I own. Modest, but a better blade than I've seen on many.

Work of Houshan. A workshop that still produces shibriyas.

Thanks for translating Lotfy.
I do not know the specific case of Abdulrazaaq, but this type of niello work is well known from Iraq and it has been used on Kurdish and Marsh Arab types of daggers. Funny, because the real origin of this type of niello work is Tbilisi Georgia and kindjals made with similar decoration and mounting in late 19th century. Other shibriyas with niello are different and in less "foreign" style, like the one in Mariusgmioc pic (middle, I also have a similar one)
Lotfy and Artzi, you have both shown examples of shibriya of good+ quality, but these consist less than 5% of the production and are not in a representative style, like those of Houshan, which are the most dominant and typical type.

As requested, image of the blade and as mentioned, images of niello shibriyas with one similar to Artzi's.
