The shuangshou dao is a Chinese two-handed sabre with a long grip and a broad, usually slightly curved blade. It appears in late Ming sources and continues as a family of long sabres through the Qing into Republican-era practice weapons that influenced the miao dao. In the field it was a shock weapon used for aggressive cuts, anti-cavalry work, and to break dense infantry lines. Manuals such as Ji Xiao Xin Shu and Wu Bei Zhi outline training sets for long sabres, while surviving examples show high-quality lamination and battlefield weight rather than ceremonial lightness.

History and Evolution
Origins and Ming codification
- Long sabres appear in late Ming drill books alongside long straight changdao.
- Units trained to use extended grips for reach and leverage against armoured opponents and horses.
Qing continuation
- Two-handed sabres persist in limited military roles and court collections.
- Single-handed yanmao dao dominates service, yet workshops continue to mount longer battlefield sabres for specialist troops.
Republican-era reorganisation and the miao dao
- Early 20th-century martial reforms revive the long sabre as a training and militia weapon.
- The miao dao inherits the two-handed format with slimmer, faster blades for drilling while retaining the long-handled dao concept.
Modern practice and revival
- Contemporary Chinese martial arts schools teach long-sabre sets derived from Ming and Republican sources.
- Makers and museums catalogue surviving shuangshou dao with increasing technical scrutiny, clarifying distinctions with changdao and miao dao.
Terminology you will see
- Shuangshou dao: literally “two-hand sabre” with curved blade.
- Changdao: “long sabre” often straighter and more sword-like in texts.
- Miao dao: modern long sabre lineage with slimmer training blades; 20th-century term.
Handling Notes
- The long grip and forward blade mass favour committed cuts, draw-cuts, and diagonal hews.
- Wide stance, sliding hand changes, and hip rotation are integral to historical sets.
- Against cavalry, rank-and-file drilled to strike forelegs or riders after a parry with the long handle acting as a lever.
Advantages and Disadvantages
Advantages
- Reach over single-handed dao and jian.
- Devastating cutting power against textile and light lamellar armour.
- Two-hand leverage improves control in binds and parries.
- Psychological shock value in close ranks.
Disadvantages
- Weight and length reduce endurance for extended marches and cramped terrain.
- Slower recovery than single-handed sidearms.
- Needs formation tactics or space to excel.
- Transport and scabbard wear are non-trivial for very long blades.
Comparison with Similar Weapons
| Weapon | Region and Era | Blade | Typical Weight | Use Case | Key Difference to Shuangshou Dao |
|---|---|---|---|---|---|
| Changdao | China, late Ming | Often straighter, long | 1.5 to 2.5 kg | Line-breaking, anti-cavalry | Straighter blade and terminology in texts; overlap exists but changdao is not necessarily a curved dao |
| Miao dao | China, 20th c. | Slimmer, long, curved | 1.2 to 1.9 kg | Training, militia, duelling | Later, faster lineage; typically livelier balance and modern curricula |
| Ōdachi / Nōdachi | Japan, medieval | Very long, curved | 1.5 to 3.0 kg | Anti-cavalry, temple offerings | Mounted differently with Japanese tang and mounts; cutting mechanics and footwork differ |
| Zweihänder | Europe, 16th c. | Very long, straight | 2.0 to 3.5 kg | Pike-breakers, guard troops | Straight double-edged sword with complex hilt and ricasso; thrust and half-sword options common |
| Ssangsudo | Korea, Joseon | Long, usually straight | 1.5 to 2.5 kg | Court guard, elite troops | Korean manuals emphasise ceremonial and guard roles alongside field use |
Legacy
- The shuangshou dao preserves a Chinese approach to great-sabre design that balances cutting power with controlled curvature.
- Its practice revived interest in Ming military drills, influencing modern Chinese long-sabre methods.
- In popular culture and martial arts, it bridges historical battlefield weapons and the sleek miao dao of the 20th century.

Collectors Guide
What Drives Value
- Period and authenticity: Late Ming two-hand sabres with credible provenance command a premium.
- Blade quality: Visible lamination, crisp taper, original polish remnants, and sound edge geometry.
- Mounts and completeness: Original guard, grip core, wrap, ferrules, and scabbard fittings.
- Dimensions: Desirable long blades with secure, two-hand grips.
- Condition: Minimal corrosion, straight blade, intact peen; honest service wear preferred over heavy restoration.
- Provenance and literature: Pieces cited in reputable publications or ex-important collections increase confidence and price.
Red Flags
- Over-cleaning or mirror polishes hiding welds and flaws.
- Fresh artificial patina on mounts; mismatched or recently made scabbards presented as original.
- Overlong modern blades fitted to older mounts.
- Vague dating that drifts toward “Ming style” without specifics.
Care and Conservation
- Neutral microcrystalline wax on cleaned steel; no abrasive buffing.
- Stable humidity and padded supports to prevent grip splitting.
- Gentle scabbard use to avoid scraping loose horn or brass throats.

Buyer’s Checklist
- Measure everything: overall, blade, and grip lengths; weight and balance point.
- Photograph tang and construction if disassembled by a professional.
- Request metallurgical notes or macro images of lamination where claimed.
- Match patina across blade, guard, grip ferrules, and scabbard mounts.
- Verify literature or exhibition history.
- Budget for conservation and a custom support.
Training and Reproductions
- Reproduction shuangshou dao and miao dao suitable for form work are available from reputable smiths.
- For contact cutting, choose through-hardened or well-tempered blades with conservative weights and secure peens.
- Always pair with appropriate protective training standards.
Frequently Asked Clarifications
Is a shuangshou dao the same as a miao dao?
No. They share the two-handed dao format. Shuangshou dao refers to historical two-hand sabres documented from the late Ming onward. Miao dao is a later term tied to Republican-era curricula with typically slimmer, livelier blades.
How does it differ from a changdao?
Changdao in texts often means a long, sometimes straighter sabre. The categories overlap in period sources. Surviving curved two-hand sabres are commonly described as shuangshou dao in modern cataloguing.
Seven Swords Takeaway
- Two-handed Chinese sabre with late Ming roots and a living legacy through the miao dao.
- Battlefield weights and long grips deliver reach and cutting authority.
- Authentic Ming two-hand sabres are scarce and expensive; Qing and Republican long sabres are more attainable.
- Condition, completeness, and provenance are decisive for value.
