The Evolution of Longquan Swords: A 2,600-Year Journey Through China’s Blade-Making Heritage

Introduction: Where Dragons and Steel Meet

Nestled in Zhejiang province’s misty mountains, Longquan (龙泉) – meaning "Dragon Spring" – has been the holy grail of Chinese sword-making since the Spring and Autumn Period (771–476 BC). This region didn’t just produce weapons; it forged the soul of Chinese martial culture, blending Daoist metallurgy with imperial patronage and warrior philosophy.

At LOONG BLADE, we continue this legacy by merging ancient Longquan techniques with modern precision, offering collectors living pieces of history.

Chapter 1: The Bronze Age Beginnings (771–221 BC)

The Ou-Yue Kingdom’s Secret

Longquan’s sword-making tradition began with the Ou-Yue tribes, who pioneered:

• Composite casting: Layering bronze with tin for flexible spines and hard edges
• Inscribed blades: Early swords featured mysterious bird-worm seal scripts (鸟虫篆)

Legendary Example: The Sword of Goujian, buried for 2,000 years yet untarnished, showcases this era’s metallurgical genius.

Chapter 2: The Iron Revolution (Han to Tang Dynasties, 206 BC–907 AD)

Daoist Alchemists Advance Metallurgy

Longquan smiths became masters of wrought iron:

• Bai Lian Steel (百炼钢): Folding iron 100+ times to remove impurities
• Differential hardening: Using local clay to create proto-hamon patterns

Imperial Endorsement:

• Tang Dynasty generals commissioned Longquan dao (single-edged sabers) as standard military issue
• The famous Zhanmadao (horse-chopping sword) measured 6+ feet long

Chapter 3: The Golden Age (Song to Ming Dynasties, 960–1644 AD)

The Three Great Longquan Styles Emerged

Cultural Peak:

• 1,200+ forges operated in Longquan during the Ming Dynasty
• Swordsmiths became national heroes defending against Japanese pirates (倭寇)

Chapter 4: Decline and Revival (Qing Dynasty to Modern Era)

The Dark Ages (1644–1911)

• Qing Dynasty bans on private sword ownership nearly erased the craft
• Surviving smiths disguised swords as agricultural tools

20th Century Renaissance

• 1956: Chinese government revives Longquan as a cultural heritage site
• 2006: Traditional Longquan sword-making listed as National Intangible Cultural Heritage

Modern Masters:

• Chen A’xiang (陈阿昌): Last living holder of the "72-step folding" technique
• Shen Guangpei (沈广隆): 4th-generation smith blending tungsten alloys with ancient methods
