This strange sword is a form of straight dancing variety said to have been bathed in blood.(probably the owners) Typically it is razor sharp and exactly matches the dancing cousin famous as a heraldic, waving and shimmering march past sword for heralding VIPs and the ruler. It is used for all the Funun performances and in combination with the Terrs shield. It came into existence in the early reign of Saiid the Great....around 1830. My view is that it is a dangerous item where a simple slip could cause great loss of blood owing to its vicious blade.
