The traditional Chinese sword is commonly known as a "jian" or "dao," depending on the specific type of sword. These two terms encompass different designs and styles of Chinese swords.

1. Jian: The jian is a double-edged straight sword with a slender, pointed blade. It is often referred to as a "Chinese straight sword." The jian is known for its precision, agility, and versatility. It has a history dating back over 2,500 years and is considered one of the oldest types of swords in China. The jian is commonly associated with martial arts and has been used in both combat and ceremonial contexts.
2. Dao: The dao is a single-edged, curved sword that resembles a saber or a scimitar. It is sometimes referred to as a "Chinese saber." The dao features a slightly curved blade, which is often wider near the tip and tapering towards the hilt. It is renowned for its cutting power and slashing techniques. The dao has a rich history in Chinese martial arts, military applications, and historical conflicts.

Both the jian and dao have different variations and regional styles across China, each with its own unique characteristics and purposes. Chinese swordsmanship encompasses a wide range of techniques and forms, emphasizing both defensive and offensive maneuvers.

It's important to note that Chinese swords come in various designs and types beyond just the jian and dao. Different regions and historical periods in China have given rise to different sword styles and names, such as the "wodao" (long-handled saber) or the "taijijian" (sword used in Tai Chi). The diversity of Chinese swords reflects the rich martial heritage and cultural significance of weaponry in China.
