The Dadao (大刀), meaning “big sword,” is a broad-bladed Chinese weapon known for its simplicity and power. Originally rooted in agricultural tools, it evolved into a formidable weapon favoured by militias, railway guards, and nationalist forces during the early 20th century. Though never a formal military standard, its practical design and emotional symbolism left a lasting mark on Chinese martial heritage.

History and Evolution
- Late Qing Origins: Inspired by peasant tools such as cleavers and agricultural choppers.
- Warlord Era (1916–1928): Gained traction among militias and irregular troops due to ease of production.
- Sino-Japanese War (1937–1945): Nationalist forces used the Dadao in propaganda and skirmishes, especially in urban close-quarter fighting.
- Post-War Decline: Obsolescence set in as firearms became dominant. The Dadao survived as a ceremonial and symbolic item.
Its use was often improvised, with regional workshops producing locally adapted variants.

Legacy
The Dadao became a cultural icon during the nationalist resistance. It featured in propaganda posters, folk songs, and martial arts lore. Its image is still evoked in literature and film to symbolise raw patriotism and the struggle of common people. The “Big Sword Units” became legendary, though their battlefield impact was often exaggerated.
Today, the Dadao is preserved more for its symbolic and cultural resonance than its battlefield utility.

The Seven Swords Takeaway
The Dadao is a product of necessity, forged in a time of political fragmentation and warfare. Its blunt force, accessible construction, and iconic shape made it the sword of the people rather than the elite. Though eclipsed by firearms and more refined blades, the Dadao’s legacy endures in Chinese martial tradition and historical memory.
