I was taking the 35 cm (about 13.7 in.) to indicate OAL, which would mean that the blade would be about 8–9 in. in length. That's probably bigger than most Jewish circumcision knives but I don't know what Persians used. Also, Jewish circumcision knives mostly have straight edges, whereas old Indonesian knives used for the same purpose tended to have curved edges (though not as curved as this knife).

To me the blade looks too thin and the curvature too severe to have come from the thickest part of a shamshir adjacent to the hilt.
