It is possible that both blade and hilt are kadjar. The star symbol actually appears in Azerbaijan, both Persian and independent; here one can see a quadara with Qajar coins, making persian attribution easy. Again one might speculate that the blade is from somewhere else, but I believe it is a local Iranian (Azerbaijani ?) production:
