this is the weapon lay ont for Shadow who is Silva's twin.
the sword is called a Gig sword due to it being so big, it has crystals in it that stops the use of specal powers when the blade hit someone, his throwing knifes are the same but they can travol in one shadow and come out a diffrent shadow.
Shadow has the power of shadow teleportation just like the knifes he throws, he is a evil bastard and loves to hurt things abd dislikes humans.
