Named weapons have a long tradition in wuxia stories. In Crouching Tiger, Hidden Dragon, the famed Green Destiny is one such sword.
Green Destiny is a jian sword. Unlike the dao sword, the jian sword has a double-edged blade and a straight grip. Jian swords are traditionally known as “the gentleman of weapons.” Though two-handed jian swords exist, they were designed for martial arts rather than as combat weapons; one-handed jian swords were the norm.
Throughout the course of the movie, we learn that this exquisitely crafted sword is 400 years old. Its custodian tells the audience that it is “seven-tenths of an inch thick” and was crafted with techniques that had been lost to time.
