Kusarigama – Chain and Scythe Weapon

In the world of martial arts, weapons have always played a significant role. One of the most unique and deadly weapons is the Kusarigama, a chain and scythe weapon that originated in Japan. In this article, we will delve into the history, components, techniques, and advantages of the Kusarigama.

History of Kusarigama

The Kusarigama is said to have been developed during the feudal period in Japan, around the 15th century. It was a weapon primarily used by the Ninja, who were known for their stealth and cunning tactics. The Kusarigama was a perfect fit for their style of fighting, as it allowed them to keep their distance from their opponents while still being able to deliver lethal strikes.

Some scholars suggest that the Kusarigama evolved from the Jingama, a sickle-like tool used to sever a horse’s ropes in case of a fire. The Jingama also served as a weapon and, as per Nawa, it might have been paired with a Konpi (a chain featuring a weighted end and a wrist loop). This combination was wielded in both hands for horse protection against thieves. Another theory proposes that the Kusarigama originated from the Tobiguchi, an axe variant with a robust haft and a short pick-like blade.

Despite its intimidating appearance, there’s no record of the Kusarigama being employed in large-scale battlefield combat. Its long chain could pose a risk to allies, and it would prove ineffective against armor. The weapon shines when used against a sword-wielding opponent, but less so against longer weapons like spears, Naginatas, or bōs. It might have been carried as a lightweight, compact backup weapon. It is believed the Kusarigama gained popularity during the Edo period, serving as a countermeasure against swordsmen and a training tool, despite being first crafted in the Muromachi period.

From the 12th century up to the Tokugawa shogunate era, several fighters specialized in this weapon. One notable individual was Yamada Shinryukan, who defeated numerous swordsmen but met his end trapped in a bamboo grove by Araki Mataemon, unable to swing his kusarigama. The weapon has also been associated with ninja use and was a favorite pastime for idle warriors. It attracted rural students desiring a unique skill for local festivals and was even used by samurai women.

The arts of Kenjutsu, Jujutsu, and Naginatajutsu all incorporated Kusarigamajutsu, which combines elements of Kamajutsu, Kusarijutsu and Fundojutsu. These respectively refer to the sickle, chain, and weight components of the weapon. Kusari-fundo denotes the combination of the chain and iron weight.

The handle of a Kusarigama typically features Raden, an inlaid lacquer wood containing fragments of mother-of-pearl, often with metal bands or strips reinforcing either end.

Types Of Kusarigama

There are three distinct types of Kusarigama. The first features a sickle-shaped weapon (Kama) with a chain connected to the end of its shaft. The deployment of this type varies based on the ryū (school), where the weapon is held in one hand while the chain and weight are held in the other, to be swung at the opponent. Depending on the visibility of the weapon’s weight motion, it could potentially be deflected or blocked. A single hit with this type of Kusarigama may not halt an attacker, necessitating the wielder to reel in the weight for a subsequent strike.

The second version of Kusarigama has the chain affixed at the base of the blade, resulting in a more powerful weapon. This version facilitates rapid attacks and can still be used effectively even if deflected. It requires only one hand to operate, leaving the other free for additional combat actions.

The third version of Kusarigama boasts a straight blade set at right angles with a handguard on the blade side. The chain is attached to the base of the weapon and is manipulated with both hands, akin to the first type of Kusarigama.

Components of Kusarigama

The Kusarigama consists of two primary components, the Kama and the Kusari (chain). The Kama is a sickle-like blade that is attached to a wooden handle. The blade is usually about 10-15 inches long and has a curved edge. The Kusari, on the other hand, is a chain that is approximately 10 feet in length and is attached to the base of the Kama.

Kusarigama Construction

The Kusarigama is a unique weapon that requires specific construction techniques to be effective. In this section of the article, we will delve into the construction of the Kusarigama and explore the materials used, the design, and the process of constructing this weapon.

Materials Used

The Kama, or the sickle-like blade of the Kusarigama, is typically made of high-carbon steel. This type of steel is preferred for its durability, sharpness, and resistance to corrosion. The Kusari, or the chain component, is made of iron or steel and is typically 10 feet in length. The wooden handle is usually made of hardwood such as oak or maple, which is both strong and durable.


The design of the Kusarigama is unique, and it has evolved over the years to become more effective. The blade of the Kama is typically curved to allow for more effective cuts, and the handle is designed to provide a comfortable grip. The chain component of the weapon is also designed to be flexible, allowing the user to swing it in a variety of directions.

Process of Construction

The construction of the Kusarigama involves several steps. First, the blade of the Kama is forged from high-carbon steel using a hammer and anvil. Once the blade is shaped, it is hardened using heat and then tempered to give it the right balance of hardness and toughness.

Next, the chain component is constructed. The individual links are made by hand using a process called wire drawing. The links are then welded together to form the chain. Then, the wooden handle is carved to the desired shape, and the Kama blade is attached to it using a ferrule, which is a metal band that secures the blade to the handle. The chain component is then attached to the base of the Kama using a swivel, which allows the chain to rotate freely.

Techniques of Kusarigama

The Kusarigama is a versatile weapon that can be used for both offense and defense. One of the most common techniques is to swing the Kama at the opponent while holding the chain with the other hand. This technique allows the user to strike the opponent from a distance while keeping them at bay. Another technique is to throw the Kama at the opponent using the chain, making it an effective ranged weapon.

Usage Techniques

The typical method of attack with this weapon involves swinging its weighted chain overhead in a large arc, followed by whipping it forward to ensnare an opponent’s weapon or immobilize their limbs. This technique allows the Kusarigama wielder to swiftly advance and strike with the sickle end.

Advantages of Kusarigama

The Kusarigama has several advantages over other weapons. First, it is a versatile weapon that can be used in a variety of situations. Second, the chain component of the weapon allows the user to keep their distance from their opponent, making it an effective defensive weapon. Finally, the Kusarigama is a difficult weapon to defend against, as the user can strike from a distance, making it a lethal weapon in the hands of a skilled practitioner.

Final Thoughts

The Kusarigama is a unique and deadly weapon that has a rich history in Japan. It is a versatile weapon that can be used for both offense and defense, and its components allow the user to keep their distance from their opponent while still being able to deliver lethal strikes. In the hands of a skilled practitioner, the Kusarigama can be a deadly weapon that should not be taken lightly.
