Longquan Sword: The 2,600-Year Legacy of China's Legendary Blade
For over two millennia, the name Longquan (龙泉) has been synonymous with the pinnacle of Chinese swordsmithing.
Located in Zhejiang Province, this small city has produced some of the most revered blades in Chinese history — swords whose legends have been passed down through dynasties, wars, and empires.
At DRACBLADE, we honor this tradition by offering precision-crafted decorative Longquan swords that capture the artistry and spirit of these ancient masterpieces. In this article, we explore the origins, evolution, and intricate forging craftsmanship that make Longquan swords legendary.
1. Origins: The Birth of Longquan Swordmaking
Legend of Master Ou Yezi
The story of Longquan swords begins in the Spring and Autumn Period (770–476 BCE), during the Eastern Zhou Dynasty. According to ancient texts, the legendary swordsmith Ou Yezi (欧冶子) — often called the "Father of Chinese Swordsmithing" — was commissioned by the King of Chu to forge a set of exceptional blades.
Ou Yezi traveled across China in search of the finest iron ore and the purest water for quenching. He eventually settled at the foot of Qinxi Mountain (秦溪山) near present-day Longquan, where he discovered two distinct veins of ore — one yielding iron with unparalleled hardness, the other providing superior toughness.
The Discovery of "Dragon Spring" Water
Legend holds that when Ou Yezi prepared to quench his first blade, the sky darkened and seven stars appeared in daylight. A dragon descended from the heavens, coiling around the anvil as the blade was plunged into the spring water. The resulting sword was so sharp it could cut through iron like mud.
This is how Longquan — literally "Dragon Spring" — got its name. The seven stars are said to represent the Big Dipper, and the flowing pattern on the blade resembles a dragon's scales, which remains the signature aesthetic of Longquan swords to this day.
The Seven Legendary Swords of Ou Yezi
Ou Yezi is credited with forging seven legendary swords for the King of Chu:
| Sword Name | Chinese | Notable Attribute |
|---|---|---|
| Longyuan | 龙渊 | The original "Dragon Abyss" — later renamed Longquan to avoid an emperor's taboo |
| Tai'e | 泰阿 | A sword of majesty, said to glow with an aura of imperial authority |
| Gongbu | 工布 | Known for its unique wavy grain pattern |
| Zhanlu | 湛卢 | A sword so pure it could distinguish good from evil |
| Juque | 巨阙 | Massive in size, said to be unbreakable |
| Yuchang | 鱼肠 | A short, flexible sword hidden inside a fish |
| Chunjun | 纯钧 | A sword of flawless beauty, prized as a treasure of the kingdom |
These seven swords established the foundation of Chinese metallurgy and set the standard for all Longquan blades that followed.
2. Historical Evolution Through Dynasties
Han Dynasty (206 BCE – 220 CE): The Iron Age of Chinese Swords
During the Han Dynasty, Longquan's smithing techniques underwent a revolutionary transformation. Iron replaced bronze as the primary material, and new methods emerged:
- ✔ Hundred-Refined Steel (Bailian Gang) — Blades were heated, folded, and hammered hundreds of times to remove impurities and create layers
- ✔ Pattern Welding — Different grades of steel were forge-welded together to create visible grain patterns
- ✔ Differential Quenching — The blade edge was hardened while the spine remained flexible — a technique the Japanese later adapted for katana-making
The Han Dynasty also produced some of China's finest cavalry swords, with longer blades designed for mounted combat. Longquan smiths perfected the huan shou dao (ring-pommel sword), which became standard military issue.
Tang Dynasty (618 – 907 CE): The Golden Age
The Tang Dynasty is considered the golden age of Chinese swordsmanship. Longquan blades from this period were prized across Asia, traded along the Silk Road as far as Persia and Byzantium.
The Tang hengdao (横刀) — a straight, single-edged blade — was the inspiration for the Japanese katana. Japanese monks and envoys visiting China brought Longquan blades back to Japan, where they influenced the development of Japanese swordsmithing traditions.
Tang-era Longquan innovations included multi-layer forge welding (up to 50 layers), fuller grooves to reduce weight without sacrificing strength, and elaborate fittings with gold and silver inlay influenced by Silk Road cultures.
Song Dynasty (960 – 1279 CE): Refinement and Artistry
The Song Dynasty saw Longquan swordmaking reach new heights of refinement. With a more scholarly culture, swords became not just weapons but also objects of art and spiritual significance.
Song smiths developed the "cloud pattern" (yunwen) steel, where the folded layers formed intricate patterns resembling flowing clouds or water ripples. Daoist philosophy deeply influenced Song-era swordmaking — a properly forged Longquan sword was believed to protect its owner from evil spirits, bring harmony, and embody the balance of Yin and Yang.
Ming Dynasty (1368 – 1644 CE): Mass Production and Standardization
The Ming Dynasty brought military standardization. The yaodao (腰刀) became the standard sidearm for Ming soldiers — a curved, single-edged blade optimized for slashing from horseback. Longquan became a state-designated arms manufacturing center with standardized blade dimensions, centralized quality inspection, and batch heat treatment in specialized furnaces.
Qing Dynasty (1644 – 1912 CE): Decline and Preservation
By the Qing Dynasty, firearms began replacing edged weapons on the battlefield. Qing-era Longquan swords became increasingly decorative, featuring elaborate scabbards with lacquer and mother-of-pearl inlay, gold and silver wire wrapping on hilts, and carved hardwood handles with ray skin wrapping.
Modern Era (1912 – Present): Revival and Global Recognition
After decades of war and cultural upheaval, Longquan swordmaking experienced a major revival in the 1980s. The Chinese government recognized Longquan swordsmithing as a National Intangible Cultural Heritage. Today, Longquan is home to hundreds of sword workshops, producing everything from functional martial arts blades to museum-quality art pieces.
3. The Art of Longquan Forging
Material Selection
Authentic Longquan swordmaking begins with raw material selection. Traditional smiths use a combination of high-carbon steel (0.8–1.2% carbon) for the hard cutting edge, and low-carbon steel or wrought iron for the soft, tough spine that absorbs shock.
Folding and Forging
The heart of Longquan swordmaking is the folding process (折叠锻打):
- Heating — A billet of alternating high-carbon and low-carbon steel is heated to approximately 1,000°C in a coke or coal forge
- Hammering — The smith strikes the billet, elongating it and bonding the layers
- Folding — The billet is cut, folded, and re-welded, repeated anywhere from 7 to 30 times
- Results — After 15 folds, the blade contains over 32,000 layers. After 30 folds, over 1 billion layers
Each fold serves three purposes: homogenization (evenly distributes carbon content), purification (forces impurities to the surface), and pattern creation (creates the signature grain pattern).
Pattern Welding and Grain Structure
The visible grain pattern on a Longquan sword is a map of the blade's internal structure. Different folding techniques create distinct patterns:
| Pattern Name | Chinese | Technique |
|---|---|---|
| Flowing Cloud | 流云纹 | Random folding with slight offset |
| Pine Bark | 松皮纹 | Tight, irregular folds resembling pine bark |
| Water Ripple | 水波纹 | Wavy pattern created by twisting the billet |
| Twisted Wire | 扭绞纹 | Two different steel types twisted together |
| Feather Pattern | 羽毛纹 | Symmetrical patterns resembling feathers |
Differential Heat Treatment
One of Longquan's most advanced techniques is differential heat treatment (局部淬火). A layer of clay-sand mixture is applied to the blade spine (thicker) and edge (thinner). When quenched, the edge cools faster and becomes hard (martensitic, ~60 HRC), while the spine remains tough (pearlitic, ~40 HRC). This creates a blade that can take a razor-sharp edge while being flexible enough to survive hard impacts.
Polishing and Etching
The final steps — rough polish, medium polish, fine polish, and acid etching — reveal the blade's soul. Dilute acid is applied to reveal the grain pattern: hard steel resists acid, soft steel etches darker, creating visible contrast. A high-quality Longquan polish can take a skilled craftsman several days to complete.

5. Caring for Your Longquan Sword
- Oil regularly — Apply a light coat of mineral oil or specialized sword oil to prevent rust
- Control humidity — Store in a dry environment (40–60% relative humidity)
- Handle with care — Oils from your skin can cause corrosion; wipe the blade after handling
- Proper display — Use a horizontal stand or vertical rack with a soft lining
- Avoid moisture — Never store a sword in a leather scabbard long-term
