unknown naski inscripted malchus blade?

[Norman McCormick]

Hi Cornelis?
Not sure what the references to Malchus, Biblical or historical, and Naski are. The blade looks S.E.Asian, big area I admit, the numbers appear to be a 'magic square' and the lettering Arabic script. Some or all of the aforementioned may be incorrect, I expect the experienced members will give a more definitive answer if indeed there be one.
Regards,
Norman.
