Jian is often called the "sovereign of blades". Jian was most commonly used during the Eastern Zhou Dynasty (770 BC-256 BC). According to historical records, many famous jian of great quality were made during this time at the requests of the emperors and dukes.
Ji is a weapon with a steel or bronze tip mounted on the end of a long shaft, next to which is attached a curved blade. Because of the attachment of the curved blade, the weapon can be used to both stab and slash.
The Hook Sword or Shuang Gou also known as tiger-head is an exotic Chinese weapon traditionally associated with Northern styles of Chinese martial arts, but now often practiced by Southern styles as well.
