What is Kakute?
The kakute was a metal ring with thorns on one side, used by ninjas to surprise and incapacitate their enemies. Usually placed on the middle finger, the kakute allowed the ninja to drive the thorns into the opponent's skin at strategic points, causing intense pain and, in many cases, poisoning, as the ring could be dipped in poison before the battle.
The ring was an efficient resource for the ninja, known for their ability to act stealthily. The kakute allowed them to immobilize or weaken their opponents with discretion, making the battle more favorable for the wearer. In addition, the ring was also useful for climbing surfaces, with its spikes offering greater grip on walls and structures.

Kakute features
The kakute was made of iron and usually had one to three spikes. The more spikes, the more effective the weapon. Usually, female ninjas, known as kunoichi, preferred this weapon for its discreet appearance. As women already wore rings as adornment, the kakute did not arouse suspicion.
The weapon was used with the tips facing the inside of the palm, and the quick, precise blows drove the thorns into the opponent's vulnerable spots. The poison on the tips made the attacks even more deadly, often causing quick and silent death.
Ninjutsu schools, such as Seigo Ryum and Nanban Ippon Ryu, trained their students to use the kakute with great skill, teaching capture and combat techniques with the ring. This weapon was extremely versatile and efficient, allowing the ninja to attack with precision without attracting the attention of other enemies.
Types of Kakute
There were different types of kakute, each with specific characteristics. The most common models included:
- Senriki: A serrated ring that caused deep wounds in vital areas such as wrists and neck.
- Senninriki: With two teeth, this ring was designed to maximize the impact of the strikes.
- Temanriki: A wider ring, suitable for people with larger hands, offering greater stability in combat.
These different models allowed the ninja to choose the weapon best suited to the size of their hands and the type of mission they would be carrying out.

The History of the Ninja
Ninjas, also known as shinobi, appeared around the 14th century in Japan. Their main role was to act as spies and saboteurs, and they were often hired by feudal lords to carry out secret missions. Ninjas excelled in their skills in camouflage, infiltration, and silent combat.
Although there are few detailed records of the activities of these warriors, the image of the ninja has been kept alive over the centuries thanks to their association with mystery and stealth. Many legends surround the ninja, including stories of supernatural powers, such as the ability to turn invisible or walk on water. However, the ninja's true skill lay in their discipline and rigorous training.

Conclusion
The kakute is an example of how the ninja used their intelligence and ingenuity to develop weapons that were lethal and discreet at the same time. Although the ring looked like a simple adornment, it was a powerful tool in the hands of highly trained warriors. Its effectiveness, combined with poison and surprise, made the kakute one of the most intriguing weapons in ninja history.
Ninja culture continues to fascinate people around the world, and the kakute is an important part of this rich heritage. Despite its simplicity, this small weapon played a significant role in the ninja's combat strategies, symbolizing the blend of cunning and skill that defined these legendary warriors.
