It is of pronounced diamond section, long with a rounded tip, some visible signs of a hardened or inserted edge. At the forte is a deeply engraved character which is likely to be a name or reference to a quality of the sword or owner. The hilt of the sword is mounted with brass, the guard is finely detailed with a grinning monster or taotie face, the grip carved from a solid piece of bulbous ribbed horn. The scabbard is original, mounted with thick brass, the hardwood lacquered. Good condition thoughout circa 1800, possibly 18th century.
