Developed in 15th Century China, The Butterfly Sword was used in pairs. Similar to The Dao Sword, The Butterfly was 11 inches long with 6-inch elongated “D”-Guard type handles. The blades were traditionally single-edged and sharpened. The Butterfly Sword featured a broad /wide center shaft, reinforced for strength. Along their prime use was as a slashing/cutting weapon, The Butterfly could be used as a stabbing and thrusting device. A stylized rolling pinning motion was implemented with use (creating a wide cutting arc). In addition to their cutting abilities, the “D”-Guard grips were also used as a form of Brass Knuckles (for close-in fighting).
