The Unique Sickle of Ishtar-ibbi Rajshuklam is a 3284 years old piece made by Ishtar-ibbi Rajshuklam, a farmer living in Nishapur.
Considering its age and the quality of the work, people consider it of priceless value.
It is engraved with central asian patterns and some symbols pertaining to Judaism.
This piece doesn't exist, but as a legend. It is said that in the year -1244, Eshargamelat Rajshuklam, the owner, made use of it in Akkad to empower the Rajshuklam family. Now it is lost, or broken, we will never know.
