Help with yatagans' inscriptions

[Zifir]

Hi,
The first one is:

Amel-i Şerif Sahib Osman Ağazade Abdülcemil

Work of Şerif, Owner Abdülcemil, son of Osman Agha

The first line of the second script was difficult to give meaning for me although there is no difficulty in reading it.

Kendi nutk-ı pakdır nutk eyleyen Perverdegar


(My somehow nonsensical translation is: He himself is a well spoken word since it is Allah who make him speak. Some Sufi references here that I am not familiar)

that's best I can
