This was one of the nicest blades I've seen on ebay:

with the nice and authentic
AA Isfahani cartouche. My best comments to the seller. Very good taste, always accurate and professional descriptions and very nice items. Whoever did polish and etching for this blade (as well as scabbard and tip, etc) did an awesome work... and congratulations to the buyer. The blade like this will be valued at a much higher premium in Saudi Arabia:-)
