I agree "if any effort was made to correctly drop-forge a blade, then they would not restrict it to a single item - they would produce a minimum of 500 - 1000 units". But where are these other units when veteran collectors across the globe have never seen (a real) one? Supplemented with the exemplary information Dave has provided it is obvious to me that this is someone's metallurgy and authentication project designed to fool collectors. IMHO
