The presence of Shah Abbas, Assad-Allah, etc. cartouches does not imply Safavid origin. this has been written and discussed so many times before
So many of those cartouches were added later. The blade of presentation saif above is not Safavid. The one with two gold inlaid cartouches is more likely. but could be anywhere of 18-19 C i.e. early-late Qajar period.
