The Chinese war sword is commonly referred to as the "Dao" (pronounced as "dow"). The Dao is a general term used to describe various types of Chinese sabers or swords that were used in warfare throughout Chinese history.

The Dao typically features a curved, single-edged blade with a relatively broad and heavy design. It is designed for slashing and cutting, making it effective in close-quarters combat. The Dao often has a guard and a hilt that can vary in design, allowing for different handling styles and techniques.

The Dao played a significant role in Chinese military history, with various dynasties and armies utilizing it as a primary weapon on the battlefield. Its versatility, cutting power, and relatively straightforward construction made it a popular and practical choice for infantry and cavalry alike.

In addition to the general term "Dao," there are also specific types of Chinese war swords, such as the "Wodao" (wide-blade saber) or the "Yanmaodao" (goose-quill saber), each with their own unique characteristics and regional variations.
