A Persian Peshkabz for comment and help with translation

[GePi]

Hi,
I have another recently acquired piece to show, this time a Persian Peshkabz.

The blade is nice wootz with a not quite consistent ladder pattern. On the forte of the blade it shows a typical chiseled douple cartouche, but chiseled on the spine is a very interesting repeating pattern with scant remains of gold laid onto the background which must have looked spectacular with all the gold in place. The spine also has a small chiseled name at the forte which I believe says 'amal-e ali' and something after that which I cannot make out.

On the front strap chiseled is a simple vine pattern, also with a bit of remaining gold in the background.

Finally the backstrap has a lengthy high quality chiseled calligraphic inscription which wraps around to the pommel end, which I would love to have translated of course.

Thanks for looking!
