Current Weapons of Use

Animals/Insects - Animals are also considered as weapons. Some animals have chemical reactions when fed food pills.

Bombs - Oddly enough, bombs are used in Naruto, but not often. So far there has only been 3 different bombs seen in the series: Smoke, Gas and Light. The smoke bomb is either used as a distraction or an escape tool. The gas bomb is simply a poisonous gas bomb which causes coughing once breathed in. The light bomb is used to blind a person.

Exploding Tags - A commonly used weapon, exploding tags are pieces of paper with the Japanese character "Baku," which means "explode" written on it. These tags can be easily placed on various items and will ignite them and explode after a short amount of time.

Food Pills - You would be surprised to consider this a weapon, but it is. Food pills allow the user to double their chakra and even fight three days non-stop. Also when fed to some animals it creates a chemical reaction. Kabuto, Orochimaru's #1 subordinate has been known to use a blood pill, which regenerates blood lost in battle. The AkimichiClan (Chouji's family) uses a set of 3 pills that greatly increase the user's abilities and can even change their appearance.

Fuuma Shuriken - The fuuma shuriken is also known as the windmill shuriken. It is much larger than the normal shuriken and it is also collapsible. Though the accuracy rate is much lower the effects of being hit by a fuuma shuriken are far more deadly.

Katanas - Katanas are one sided swords used as the default weapon for ANBU members. They are also used by the samurai body guards of Gatou.
[Only Chuunin and up may have Katanas.]

Kunai - The Kunai is a kind of basic dagger that all ninjas use. It is all-purpose and can be used as a throwing knife or to stab at your opponents. It is extremely vital for all Shinobi to have.

Makibishi - Makibishi are small nails used to attack the opponent with.Just like the Senbon Needles, it does not hit the opponent very often. Some ninjasuse this weapon as a distraction for his/her main attack. Makibishis have 4 pointed spikes and are also used to slow down an opponent. Its shape makes it so at least one point is always facing up.

Ointment - Ointments are simply used as a healing cream or used to relieve pain.

Shuriken - The shuriken, otherwise known as ninja stars, is a very deadly and commonly used weapon. There are two types of shuriken: the tiny ones which are more smaller and easier to throw, and the Fuuma Shuriken: a huge shuriken used for fast and easy killing. It is very unwieldy, but if it hits you, you're as good as dead! While the Fuuma shuriken is preferred by the older and more experienced Shinobi, some Genin find it easier to use than the regular sized shuriken.

Umbrella - Umbrellas are used by the Shinobi of the Rain village. These umbrellas are mainly used to conceal thousands of needles which, when the umbrella is thrown into the air spinning, spread out in a rain-like fashion.

Wire - Wires are simple thin metal wiring often tied to the kunai or shuriken and thrown to in groups to fasten an enemy to a tree or rock.

Senbon Needles - Senbon needles, while mainly used for Acupuncture (a form of Chinese healing that includes sticking needles in strategic spots on your body, redirecting ki or your life force so that it balances out) some Shinobi, properly trained, can use them as deadly weapons. One of the reasons it is not all that popular is it requires extreme accuracy and speed, fore these are only deadly if they hit a vital area of the body. Masters of the Senbon Needle combat are in a way, masters of illusion. With the right precision and timing, a Shinobi can throw a Senbon Needle seemingly at a vital target on an ally, but actually missing it by a few inches. This causes the ally to go into a death-like trance in which the Shinobi will appear dead. Even if the opponents were to take precautions to see if they are really dead.

Iron Knuckles - Iron knuckles are pointed knuckle weapons with a blade on the outward facing end. Extremely useful in hand-to-handcombats. This weapon is primarily used by Asuma.

Puppets - I don't have a basic description for this but you know that they're used for long range combat and etc.

Soldier Pills - These pills taken by Kiba allows him to fight for three days and three nights non-stop.

Scrolls - Are used for many things such as summoning or medical purposes.

Staff poles - Blunt weapons which are good for deflecting and defending.

Bells/Flutes/Whistles - A genjutsu weapon which makes illusions of the enemy and puts them under high hysteria or hallucinations by hearing its sound.

Exploding Pouches - A variation on the exploding note, these small pouches can be attached to a target and then explode a few seconds later.
