Sokka's weapons

Sokka has many weapons including his boomerang, club, sword, spear and machete. He has also been seen using a kukri and Southern Water Tribe Warriors are shown to be trained in usage of pikes, so it is likely that Sokka is as well.

Club


Sokka's club is a blunt instrument Sokka uses to club people with. It appears that Sokka has obtained this weapon while in the Southern Water Tribe. He has had it since before the series started, and was seen with it defending his village during a Fire Nation raid. In "Avatar Day", his club is seen when the Rough Rhinos go through the belongings that the gang left behind. Though its recovery is not shown on screen, it is clear Sokka did retrieve it, as it is seen in several following episodes.

Boomerang


Sokka's boomerang was given to Sokka by his father before he left with the warriors of the Southern Water Tribe. It is one of Sokka's most prized possessions. In the episode "Avatar Day", Sokka loses his boomerang and states that it was like "losing a part of (him)self". He gets it back towards the end of the episode from a Rough Rhino.

Sokka used his boomerang to defeat Combustion Man when no other member of the group could get close enough to him.

Sokka lost his boomerang while trying to save his and Toph's life during the final battle. It is unknown if he ever found it again.

Sword


When training with Piandao, Sokka made his own sword using ore from a meteorite. The material used gave the sword a distinctive black color. The sword is also able to cut through strong metals with little effort.

Sokka's sword is a Jian (Chinese straight sword). It is now part of his standard armament, along with his boomerang and club.

The bottom of the hilt contains the symbol of the Order of the White Lotus.

Sokka lost his sword while saving his and Toph's life during the final battle. It is unknown if he ever found it again as well.

Machete


Sokka does not use his machete as often as his sword or his boomerang, in fact he usually uses it for menial tasks such as shaving and picking his teeth, but he did use it in "The Swamp" for hacking at the foliage, and in "The Desert", where he spots a cactus and slices part of it open to reveal a water-type drink inside.

Spear


Sokka's Spear (or Pike) is hardly used. He is seen using it to "Spear Fish" in "The Boy in the Iceberg". His spear was snapped in half by Zuko in "The Avatar Returns".

Bone Club
Sokka has a club that, like his spear, appears to be made out of a whale jaw. Sokka never actually uses his bone club on screen.
