What is a Chang Dao Sword?

TLDR: The Chang Dao sword is a massive two-handed weapon from Tang and Ming dynasties, used by elite infantry to break enemy formations and counter cavalry attacks.

When I first laid eyes on a changdao sword, I was absolutely mesmerized. There’s something about its long, graceful blade that just commands attention. It’s not just a weapon; it’s a piece of art that tells a story of Chinese martial history. The changdao, which literally means “long sword,” is a fascinating blend of form and function that emerged during the Ming Dynasty.

Brief History of the Changdao Sword

The changdao sword, a formidable two-handed weapon, has a fascinating history that spans several Chinese dynasties. Its origins can be traced back to the Tang dynasty (618-907 AD), where it first appeared as a preferred weapon for elite vanguard infantry units in the Tang army. During this period, the changdao was described as having an impressive overall length of seven feet, with a three-foot-long single-edged blade and a four-foot-long pole grip.

Interestingly, the changdao seems to have fallen out of favor after the Tang dynasty, only to resurface during the Ming dynasty (1368-1644 AD) with a slightly different design and purpose. This resurgence of the changdao particularly intrigues me, as it demonstrates how weapons can evolve and adapt to meet the changing needs of warfare over time.

During the Ming dynasty, the changdao gained prominence as an effective weapon against Japanese wokou pirates who were raiding the Chinese coast. General Qi Jiguang, a notable military leader of the time, played a crucial role in popularizing the changdao. He acquired a Japanese sword manual, studied it, and modified the techniques for his troops. What fascinates me about Qi’s approach is his willingness to learn from potential adversaries and adapt their techniques to create a more effective fighting style.

Physical Characteristics of the Changdao Sword

The physical characteristics of the changdao sword are truly impressive, setting it apart from many other Chinese swords. The changdao, which translates to “long sword,” lives up to its name with its substantial dimensions. Typically, the overall length of a changdao ranges from approximately 162.5 cm (64.02 inches) to as long as 213.36 cm (7 feet). This considerable length is divided between the blade and the handle, with the blade usually measuring around 107.5 cm (42.32 inches) and the handle about 55 cm (21.65 inches).

What fascinates me about the changdao’s dimensions is how they reflect its battlefield role. The long blade, combined with an equally substantial handle, allows for powerful, sweeping cuts that would have been devastating against cavalry or in breaking enemy formations. I can imagine the intimidating sight of elite vanguard infantry wielding these massive swords on the front lines.

The weight of the changdao is equally impressive, typically ranging from 1952 grams (4 lb 4.85 oz) to about 2 kg (4 lb 6.55 oz). This substantial weight contributes to the sword’s cutting power, but also requires considerable strength and skill to wield effectively. The balance of the changdao is crucial to its handling, with the point of balance (POB) usually located about 10.5 to 11 cm (4.13 to 4.3 inches) from the guard.

Key physical characteristics of the changdao include:

• Blade width: 40 mm at the base, tapering to 26 mm near the tip
• Blade thickness: 8.3 mm at the base, reducing to 3.5 mm near the tip
• Slightly curved blade profile, especially towards the tip

One aspect of the changdao’s design that particularly intrigues me is how its dimensions compare to other swords of its era. For instance, it’s significantly longer and heavier than the Japanese katana, which typically measures around 99 cm (39 inches) in total length and weighs between 0.9 to 1.2 kg (1.9 to 2.6 lbs). This comparison highlights the unique role and fighting style associated with the changdao.

Here’s a comparison of the changdao with some other Chinese swords:

Blade Features of the Changdao Sword

The blade features of the changdao sword are truly remarkable, setting it apart from many other Chinese weapons of its time. The changdao’s blade is characterized by its impressive length, typically measuring around 107.5 cm (42.32 inches)7. This substantial blade length contributes significantly to the sword’s overall reach and cutting power.

The shape and profile of the changdao blade are particularly intriguing. It features a single-edged design, with the blade being generally straight for most of its length before curving slightly towards the tip. This subtle curvature enhances the sword’s slashing capabilities while still allowing for effective thrusting attacks. The blade’s width tapers from approximately 40 mm at the base to 26 mm near the tip, creating a sleek and efficient cutting surface.

One aspect of the changdao that fascinates me is its edge design. The single-edged nature of the blade allows for a more specialized cutting surface, concentrating the force of each strike along a single line. This design choice reflects the weapon’s primary use as a slashing and chopping tool, particularly effective against cavalry and for breaking through enemy formations.

The curvature of the changdao blade, while subtle, plays a crucial role in its effectiveness. The gentle curve towards the tip enhances the sword’s cutting power during draw cuts and slashing motions. I find it intriguing how this design element balances the need for both cutting and thrusting capabilities, making the changdao a versatile weapon on the battlefield.

Handle and Grip of the Changdao Sword

The handle and grip of the changdao sword are crucial components that contribute significantly to its functionality and handling. The changdao’s handle is notably long, typically measuring around 55 cm (21.65 inches). This extended grip length allows for a two-handed wielding technique, which is essential for controlling such a large and heavy weapon effectively.

The design of the changdao’s handle is both practical and ergonomic. It usually features a wooden core, which provides a sturdy base for the grip. What fascinates me about the changdao’s handle design is how it balances the need for strength and comfort. The long handle not only counterbalances the weight of the blade but also allows for a variety of grip positions, enhancing the sword’s versatility in combat.

Grip materials and construction for the changdao can vary, but they typically prioritize durability and comfort. Common materials include:

• Wood (such as strong hardwoods)
• Leather wrapping
• Cord wrapping (often in bold colors like red)
• Occasionally, materials like ray skin or sharkskin for added grip

The construction of the grip often involves wrapping the wooden core with leather or cord. This wrapping serves multiple purposes: it provides a secure grip, absorbs sweat, and can be replaced if worn out. In some cases, the grip might feature risers or textured patterns to enhance the wielder’s hold on the weapon.

Functionality of the Changdao Sword

The functionality of the changdao sword is a testament to its versatility and effectiveness on the battlefield. This formidable weapon excelled in various combat applications, making it a favored choice for elite infantry units during the Tang and Ming dynasties.

One of the primary combat applications of the changdao was breaking through enemy formations. Its long blade, typically measuring around 107.5 cm (42.32 inches), allowed vanguard infantry to deliver powerful, sweeping cuts that could effectively shatter enemy lines. This capability made the changdao an invaluable asset for shock tactics, enabling elite regiments to create openings in enemy defenses that other troops could exploit.

The changdao also proved exceptionally effective against cavalry. During the Ming dynasty, General Qi Jiguang found the weapon particularly useful when facing mounted opponents, such as Mongol raiders. The sword’s extended reach allowed foot soldiers to strike at riders or their mounts while maintaining a safer distance from the enemy’s weapons.

What fascinates me about the changdao’s combat applications is its dual role as both an offensive and defensive weapon. The long handle, typically around 55 cm (21.65 inches), provided leverage for powerful strikes while also offering some protection against incoming attacks.

The effectiveness of the changdao against different targets varied based on the opponent’s armor and weaponry. Here’s a table summarizing its effectiveness:

Against unarmored or lightly armored targets, the changdao’s long, sharp blade could deliver devastating cuts. Its design, which often featured a wedge-shaped cross-section, was ideal for biting into and widely separating a target as the blade passed through.

One aspect of the changdao’s functionality that particularly intrigues me is its use in conjunction with firearms. During the Ming dynasty, it served as a standby weapon for musket units.

Final Thoughts

After diving deep into the world of changdao swords, I’m even more captivated than when I started. The way these blades combine elegance with deadly efficiency is truly remarkable. From their impressive length to their specialized combat techniques, changdao swords represent a pinnacle of Chinese sword craftsmanship. While they may not be as well-known as some other historical weapons, I believe they deserve just as much recognition.
