This is the Kill Bill O Ren Ishii Handmade Katana Sword. The sword blade is contructed of carbon steel as well as aesthetic hamon. The sword comes full tang and VERY sharp. The scabbard and handle is constructed of wood and dark stained. The wood housing helped keep the blades from corroding while being stored before being properly fitted. When the sword is sheathed the handle and scabbard appear to be one piece. The handle has been desgined to contour the tang of the sword and the shape of your hand. There are two pins that lock the tang of the sword.
