Feng Chu Chan from Longquan made this sword in his first month as swordsmith at the "Traditional Japanese Sword Factory Longquan China, limited Co & Son". They use T12 steel made from the river Tarim which is the same steel as Kublai Khan made his swords from. Btw the company has only made 75000 swords like this. Yours is the number 74916. A real treasure and i would say its worth a lot of money. Because of its unpayable worth you should bring it in a museum. So everyone could see it. Thrust your own thoughts. Everyone wants to steel it from your collection.
