Windblade

The Windblade is a sword made from a strange silvery material stronger than steel. There are strange markings on the blade that shift and change under the viewer's gaze. It's pommel is wrapped in the hide of some unknown beast. The changing nature of the blade conforms itself to it's wielders temperament. Some opponents of the wielder are not even capable of seeing the blade when it is in the wielders hands. The appearance of the blade depends on the honor of the wielder. It can range from a large tanto to a no-dachi. (Crane p. 119)
