Ah, I see
The kunai is one of the most common ninja tools used by ninja besides the shuriken. As a dagger, it's mainly used to stab and cut objects such as rope. Besides being used up close, it can be thrown as well. More than often, many shinobi attach things onto a kunai such as an explosive tag. In addition, it's power can be amplified by enhancing it with the user's chakra.
As stated above, the shuriken is also the most used ninja tool. Basically, they are sharp, flattened sheets of metal that is cut into a 4 pointed star shape. The main use for shuriken is to be thrown.
The fuma shuriken is a larger version of its counterpart. The fuma shuriken, resembles a windmill when it is not folded and their blades are fairly long. They are mainly used for throwing but it can also be used to slash other ninja in CQC.
Senbons are long, thin needles. They have very little killing power, but make up for it by having it thrown at great accuracy. Senbons can be used in incapacitate or kill an opponent by hitting an artery or nerve. Another use is to tip the needle with poison and hit their opponent in a vital spot.
Flash bombs are ninja tools that create a blinding flash of light and are mainly used as distractions. A creative use with them in battle is to throw one right behind you so that the opponent will be blinded and you have time for a follow up attack.
Smoke bombs are little balls, that when thrown at the ground, create a cloud of purple smoke. This ninja tool s used to make a quick escape. Also, smoke bombs can contain different types of gases r such as poison and sleeping gas.
Scrolls are easily one of the most important Ninja tools to carry. Because of their small sizes, multiple scrolls can be carried into battle in the front pouches of a flak jacket or in a pouch. Apart from its usage as a medium, the scroll can also be used to summon animals, people and other items to their aid. Some techniques can also be stored in them such as Amaterasu.
Explosive tags are pieces of paper inscribed with a special writing. Infused with chakra, they will explode after a set amount of time, or after being ignited by flame. These can be used by setting them around the battlefield, as a trap or attached to a kunai.
A sword is a long, bladed weapon used for combat. Most ninja appear to have a preference towards long and wide blades while some ninja use shorter swords, mainly for throwing. Of note are the samurai of the Land of Iron who are nearly all seen with swords, and the shinobi of the Land of Lightning.
