Kunai is a Japanese weapon originally meant for agriculture in the Tensho Era of Japan. Two well-known varieties of kunai are the short kunai and the large kunai.

Although the kunai is the main tool in the hands of a martial arts expert, it can be used as a multi-purpose weapon, popular until the introduction of firearms. Kunai is usually associated with ninjas who used it to make holes in walls. By attaching the rope to the ring, the user could easily climb walls or trees, which required great accuracy when throwing. The kunai blade was unsharpened from soft iron and was used for digging, forging and breaking wood, plaster and the like, which could probably destroy a tool that had been sharpened or heat-treated.

The kunai used by farmers were slightly smaller than the developed kunai used by ninjas. The kunai was smaller, and there was a small handle with a hole at the top. The farmers inserted their index finger into the hole and grabbed the small handle with their other fingers. The kunai that the ninja used had a larger handle, which allowed them to hold the kunai more effectively. The hole on the kunai was mainly used to tie a rope or rope so that the ninja could hang it by the belt.

Kusarigama is a traditional Japanese weapon that consists of a Kama - a type of Japanese sickle attached to a metal chain (Manriki) with a weight at the end. It is one of the weapons used by the Ninja.

The length of the chain is from about 2.5 to 3 meters. The chain can be attached both to the handle and to the side of the sickle. The handle of the sickle at Kusarigama is usually longer than that of the ordinary Kama. 

Most techniques for using Kusarigama are found in Budo and Ninjutsu schools. The weapon is held with both hands, with one gripping the sickle and the other the chain. It (the chain) is thrown at the enemy in order to stun or entangle him with his weapon, after which he immediately attacks with a sickle. The greatest subtlety is the Maki technique (accurate throwing of the chain). The art of using Kusarigama is called Kusarigama-Jutsu.

The Naginata is a Japanese melee weapon with a long handle (about 2 m) with an oval cross section and a curved one-sided blade (about 30 cm), with which the ancient japanese samurai fought.

Over time, a lighter version of the weapon (1.2 - 1.5 m), used in training and has shown better characteristics in combat, has established itself. The first records of the use of Naginata date back to the end of the 7th century. There were more than 400 schools in Japan that taught Naginatajutsu fighting techniques. This was the main weapon of the soldiers. The naginatas were also used by women to protect their homes.

The naginata shaft was made of oak, varnished and often had an oval cross-section, which made it easier to determine the direction of the blade during rapid rotations and interceptions. The blade could be separated from the shaft by a round guard of tsuba. The blades, with the exception of those made for noble customers, were generally inferior in quality to the tips of the spearheads. The shapes of the blades also differed: in some they resembled sword blades, in others they widened towards the end. Forged katana blades were sometimes used as naginata tips.

Kanabo is a samurai weapon of feudal Japan, a type of tetsubo in the form of a metal club with a round handle, which has a thickening with a ring at the end, and, often, supplemented by small unsharpened spikes. 

Kanabo, like most weapons of the same type, was constructed from heavy wood or iron, with metal spikes or projections at one end. Its shape was the most varied: it could resemble a baseball bat, tapering from end to handle, or be completely straight from start to finish.

The size of the kanabo ranged from small sticks held with one hand to huge two-handed maces, the size of a person's height (up to 2 meters in length). It was primarily used to break the enemy's armor and cripple the limbs of his war horse. The art of wielding this bulky weapon was called kanabojutsu and consisted of training balance and strength while using the baton.

Chigiriki is a Japanese type of mace used by the ninjas. It consists of about 60 cm wooden handle and 60 - 70 cm metal chain to it, with a ball with a spike at the end of the chain. There are chains that are simply fixed to the top of the rod, and those that are placed in a cavity inside the rod and are called swinging rods. There are uses such as hitting the opponent with a weight or winding to seal the movement. Most techniques for using chigiriki are included in chigiriki-jutsu practices, which is part of the training in araki-ryu koryu - an ancient martial art, founded in early 1570 by Araki Mujinsai Minamoto.
