The weapons in the World of Avatar are distinctly unique, varying in quality, size, and usage depending on the cultures of each of the four nations. Metal is the principal material used in most of the weapons' constructions.
The Fire Nation is the most advanced in manufacturing weapons. This is due to their initiation of and subsequent experience in the Hundred Year War. The Earth Kingdom is the second most proficient due to the necessity of creating weapons to defend itself against the technologically superior Fire Nation, especially after the crumbling of the Southern Water Tribe. Each tribe is capable of crafting its own weapons, which are often made of sharpened metal or animal parts such as skins and teeth.
The wake of metalbending had an impact upon the weaponry used in combat. Since metalbenders could simply deform or otherwise disarm weapons of the earlier time period, people had to revert to other fighting forms without the usage of metal-based weapons. The metalbenders' advantage against those types of weapons was annulled with the creation of a new wave of unbendable, electrical ones.
Wind sword - While wearing a suit of armor, Aang mentioned that it was possible for him to make a wind sword, where all he needed was a handle and he could airbend a blade. Theoretically, this could be done with any element.
Axe - An average-sized axe with a blue-and-white blade and a medium-length white handle.
Battle club - A weapon used in the Southern Water Tribe. The base is carved from a polar bear femur and has a design in blue paint on each side of the blade. There is a heavy ball on the end and a notch for hooking opponent's weapons. A leather strap is attached for a more secure grip. This was another weapon used by Sokka. The club is a blunt instrument which Sokka used to strike people or animals. Sokka obtained this weapon while in the Southern Water Tribe. Using his club, Sokka defended his village during a Fire Nation raid. The Rough Rhinos found this club when they went through the belongings that Team Avatar had left behind after being attacked. Sokka managed to retrieve it, as he used it several times later. Sokka eventually lost it again to the sandbenders, after they stole Appa and all the baggage that had been in his saddle. His bone club served as a replacement.
Boomerang - A small, L-shaped weapon made of metal. It is a thrown projectile that travels in a curved path and returns to its point of origin when thrown correctly. It is the most important and treasured weapon among Sokka's weapons, as he considers it to be an essential part of his identity.
Jaw blade - Primarily a hunting tool, made by sharpening the jawbone and teeth of a large arctic wolf. One side is rigid and is used as a saw, while the other is a blade side that is used for hunting and scraping skins clean. Sokka uses this to shave the sides and back of his head. While Sokka was assisting Jet, it was shown to be able to amplify vibrations in the environment, allowing him to accurately detect intruders. The handle is wrapped in leather for a more secure grip. It is normally carried in a small pouch.
Machete - A long, cleaver-like cutting weapon. Sokka used this to clear away vines while in the Foggy Swamp.
Pike - A two-handed pole weapon or a long thrusting spear.
Spear - A weapon used in the Southern and Northern Water Tribe by warriors in battle and for hunting animals for food. The handle is made of wood and the spearhead of bone.
Tangle mine - Weapons made with a bamboo frame and covered with dried animal skin filled with skunk fish and seaweed. These mines float in the water and detonate upon contact with another object. They were invented by Hakoda, who called the weapon the "Stink 'n Sink".
Water Tribe knife - A long knife with four molars on the bottom of the blade and a leather-wrapped handle.
Bow - A weapon that uses tension to propel arrows. It is used by Longshot.
Butterfly sword - This is a short dao, or single-edged blade, also known as Wu Dip Dao or Hu Die Dao. The top of the hilt is turned up so that the fighter can flip the sword around their thumb.
Conical military hat - A round, conical hat used by the military and the Dai Li. It can easily deflect or protect the user from firebending blasts.
Crossbow - A weapon consisting of a bow mounted on a stock that shoots projectiles. It is used by the pirates.
Dual dao swords - It is a category of single-edge swords primarily used for slashing and chopping (sabers), often called a broadsword. It was mainly used by Zuko, who employed four pairs: his own, from his personal collection, used first during the Rescue in Pohuai Stronghold, and lost when his ship was blasted by pirates; a pair he stole from an Earth Kingdom swordsman who mistreated him and his uncle; a pair he momentarily "borrowed" from a Ba Sing Se guard when attacked by Jet; and a pair seen when he confronted his father, Ozai, during the Day of Black Sun.
Hook swords - Three weapons in one: a long pole with a hook at the end, a curved blade above the fist, and a spearhead beneath the handle. An experienced user can hook the ends together to double the reach of the weapons. Hook swords were Jet's primary weapon.
Ice torpedo - These are warheads full of blasting jelly with a lit fuse inside, invented by the mechanist to be used against the Fire Nation. Waterbenders are able to propel them because of the surrounding ice.
Kama - Traditional farming implements similar to a sickle used for reaping crops and also employed as a weapon.
Katana - A type of Japanese sword. It is a curved, slender, single-edged blade, with a circular guard (although it is shown with a rectangular guard during the Kyoshi Warriors' fight with Azula, much like a ninjatō's square guard and straight blade), and a long grip to accommodate two hands. It is used by the Kyoshi Warriors and is one of the most effective means of cutting through organic material.
Khukri - A curved Nepalese knife used as both a tool and a weapon. Smellerbee is the only one known to wield this weapon.
Large earth coins - These people-sized round coins are used as weapons primarily by earthbending soldiers, but some civilian earthbenders have also used these coins in combat.
Lochaber axe - A weapon consisting of a pole with an axehead mounted at its end. The axe itself is similar to tools used with crops, such as the scythe, which is designed for reaping. The point on the back of the blade is styled after the hook found on the original Scottish Lochaber Axes, in which the hook can be used for catching, hooking, and dragging clothing, skin, or weapons, not unlike the hook sword.
Meteor hammer - A weapon that consists of two weights connected by a rope or chain. Due to its flexible construction, the meteor hammer could be easily concealed as a defensive or surprise weapon.
Common military armor - A beige and green colored armor consisting of bracers, body armor, shin guards and a green colored belt-hung ge xie (protective clothing).
Naginata - A pole weapon consisting of a wooden shaft with a curved blade on the end. It has a thick, slightly curved katana-like blade connected to a long wooden pole.
Net launcher - A gun-like contraption used by the bison rustlers to capture baby sky bison, and later to trap Tenzin's students when they attempted to free the young animals.
Ninjato - A Japanese sword. It has a square grip, and a straight blade, with a small edge on its tip. The bartender of the cantina in the Misty Palms Oasis used dual ninjatos to cut fruit and ice in order to make drinks for any who stopped by.
Nunchaku - A weapon that consists of two sticks connected at their ends with a short chain or rope. They take some skill to use, since the inexperienced often wind up hitting themselves with it.
Peanut sauce bombs - Explosive weapons invented by the mechanist that are not yet fully functional.
Pearl-handled dagger - Taken by Iroh from a defeated general in the Siege of Ba Sing Se and passed on to Zuko. It has an inscription on one side saying "Made in Earth Kingdom." The inscription on the other side reads "Never give up without a fight."

Pu Dao - A type of Chinese anti-cavalry pole weapon. It consists of a broad curved blade mounted atop a long wooden pole.
Qian kun ri yue dao - A non-paired variety of the hook sword used by the pirates. The blade ends are semicircular; one resembles the sun while the other resembles the moon.
Rock gloves - These gloves are the favored weapons of the Dai Li. Agents wear the rock gloves on their hands and can use them in battle by earthbending.
Shanzi - Shanzi, or fans, are often made of iron and used in martial arts. They are used for defense and can be thrown. These shanzi are the primary weaponry of the Kyoshi Warriors and are usually used first when fighting.
Shield - A protective device, meant to intercept attacks.
Smoke pellets - A combustive weapon. Exploding on impact, they create large smokescreens to confuse and distract enemies or victims, providing the opportunity to either attack or escape.
Twin war hammer - Similar to a sledgehammer in construction and appearance, it is used to augment the potency of earthbending attacks. A rogue Earth Kingdom soldier, Gow, used this weapon to great effect in combination with his earthbending.

Catapult - Any of a number of non-handheld crew-served mechanical devices used to throw heavy projectiles a great distance without the aid of explosives. Multiple trebuchet-style catapults can be found on each Fire Navy ship, especially those that guard the nation's borders. These ornate catapults have a large dragon head statue at the top of each arm.
Chain - A weapon made of a heavy object attached to a chain with a handle, used by Ogodei. It can be used to damage buildings or tie up enemies.

Guan Dao - The Kwan/Guan Dao is a type of Chinese pole weapon. It is large and heavy and used by Kahchi of the Rough Rhinos.
Hammer - A medium-sized sledgehammer that can be used as a tool or a weapon. The hammer can also be connected to an iron chain, making it a powerful medium-distance weapon.
Jian sword - A type of straight sword wielded by Piandao and Sokka. In the hands of a master it can be far more versatile and dangerous than it appears. It is usually made of high-quality steel, but Sokka's sword was forged from a meteorite. This unique sword can cut over a foot of solid metal or rock.
Jii - A halberd-spear with a crescent moon-shaped blade on one or both sides. It is useful against both ground infantry and cavalry.
Kanabo - A long club weapon. Large and heavy, they have either metal studs or spikes running in vertical rows along the length of the weapon and have enough power to easily smash bones, even if the target uses a shield.
Military armor - Red and black armor accompanied by helmets, varying according to the wearer's status or bending ability. It may include a protective skull-shaped mask for benders.
