Restoration of an old silver Arabic dagger

In this video, I will restore this Moroccan dagger that my grandmother gave me.
Previously, this dagger belonged to my grandfather, but now it belongs to my grandmother, and now she asked me to restore it.
This dagger was made by hand in a traditional way in one of the blacksmith workshops in the city of Fez. It is more than sixty years old.
Fun watch.
Thanks :-)

No mostraste cómo te quedó al final la espada de cuerpo completo; sólo parcialmente y a oscuras (sin luz) En eso te doy un punto negativo: en la edición del video. En lo demás muy buena restauración. Saludos desde México.
