Description: http://en.wikipedia.org/wiki/Kyoketsu-shoge (<--These are typical Kyoketsu-shoge)
Apart from that image the blade glows a luminescent blue hue, and the chain a similar crimson hue. The chain (made of otherworldly silk, which has a similar strength as spider silk) measures at 24 ft (Which is unusually long), and the blade at 1 ft. The weapon has no magical properties and the glowing hues only occur if there is any external source of light (Natural or otherwise), as they redirect it.
