"Paying homage to the craftsmanship and technique of metalsmiths in the Roman Empire, our exclusive museum replica is a rough iron foundry casting like those found in Pompeii. This remarkably heavyweight replica boasts characteristic details, and makes a handsome gift for yourself or anyone who enjoys Roman history or artifacts."
The design of the hilt is obviously very similar (if not identical) to the bronze/brass swords from Florida, California, Italy (Ebay), and Nova Scotia. What's potentially significant is that the description identifies the sword as a "museum replica . . . like those found in Pompeii."
Does this get us closer to determining whence this sword design comes? The statement certainly implies that the design is based on a real Roman artifact, and it gives a geographic origin. Or perhaps these copies are based on one of the brass/bronze swords that may have been produced (perhaps from a Roman or Greek original and perhaps not) sometime in the recent past (i.e., within the last three hundred years or so).
