|First Introduced:||Adventure Time!|
These are the swords that Finn had mainly used throughout the series.
The golden sword is Finn's weapon of choice throughout most of seasons one and two. The blade is dented, chipped, and dirty, likely due to a combination of overuse, poor maintenance, and the low-strength material properties of gold. Its hilt is black with some worn leather grip-straps and a red gemstone in the pommel (possibly a ruby). In "Business Time," the Businessmen polish and sharpen the sword, making this episode the only one in which the golden sword appears to be in excellent condition. In "The Real You," the golden sword passes through the Bubble Creator and becomes four-dimensional. When Finn uses the 4-D golden sword to attack the black hole he created, Finn's golden sword is sent into the Candy Forest by the explosion. Finn is without a sword until "Mystery Train."
The golden sword, or one similar, is later seen at the end of "Fionna and Cake," when Finn and Jake are frozen in the Ice King's castle.
This design of this sword is the basis for the 24-inch toy version of Finn's sword, which is labeled as "Finn's Golden Sword of BATTLE."
In "Mystery Train," Finn obtains the root sword (the name is non-canonical), which becomes his primary weapon. He finds the sword on the caboose of the train and uses it to attack The conductor. He next uses it against the Giant in the beginning of "Belly of the Beast." It is seen briefly in "Mortal Recoil," when Finn throws it at Ice King, "Conquest to Cuteness," and in "Jake vs. Me-Mow." He keeps it in a makeshift pocket on his backpack.
The Demon sword first appears in the episode "Dad's Dungeon." In the episode, Finn and Jake go to Joshua's Dungeon to retrieve Jake's family sword. At the end of the dungeon Finn finds it encased in locks and stone. He breaks it loose and uses it to fight the final monster of the dungeon. The sword is made out of Demon Blood, which causes Blood Demon to sporadically appear and plead to Joshua (and later, Jake, thinking he's Joshua) for the return of his blood. Blood Demon is easily banished away using the spell "Kee Oth Rama Pancake." In "Return to the Nightosphere," Finn spins it in front of the blood mist cloud, and hits Marceline with it, thinking she is Hudson Abadeer. In "Daddy's Little Monster," Finn can be seen holding it throughout the video files on Jake's "new video phone." In "Beyond this Earthy Relm," Finn uses it to slash one of the heads from The Dead One. In "Gotcha!" he uses it to save Lumpy Space Princess from the Mirror Finns.
These are the swords Finn has kept at the Tree Fort.
In the episode "Morituri Te Salutamus," Finn picks up a steel sword during his first battle in the Fight King's Arena; it is similar to his original gold sword. The hilt has a leather grip and the pommel has a purple gemstone with a tiny pink gemstone slit in the center. The sword itself is in very good condition. It is later seen again in the episode "Still."
Pink Jewel SwordEdit
In "Slow Love" there is a pink jewel sword, with a hilt that is pointed on both sides and a pink gem on the bottom. The sword is seen slicing Finn's bed in half, but Finn has not been seen using it himself.
Finn has two golden katanas in the episode "Slow Love." They are used by Finn when he teaches Snorlock to do sword tricks.
These are the swords Finn had temporarily used and imagined.
Sword of the DeadEdit
Finn wields the sword of the dead to defeat Marceline's father in "Ut came from the Nightospere." Finn draws the sword from the Grass Lands before his battle and slits open the pods in Hunson Abadeer's gullet, which he is using to imprison the souls of Ooo. Finn drops the sword while reciting the incantation to open a portal to the Nightosphere.
While Finn is under the "control" of Fight King in the episode "Morituri Te Salutamus," he fights with dual swords that look like a single sword that was completely split apart from the tip of the blade to the pommel. When Finn is forced to fight Jake, he only uses one of them.
City of Thieves SaiEdit
Finn steals two sai in the episode, "City of Thieves" but they are taken by two angels at the end.
Dagger of Chilled GlassEdit
When Finn and Jake learn ninja skills in "The Chamber of Frozen Blades" Finn creates the dagger of chilled glass using his ninja skills.
Finn picks up a twisted, yellow dagger outside the windmill when he and Jake approach the "monster" in the episode "The Monster." It resembles a kris, an Indonesian dagger considered to possess magical powers.
In "King Worm," Finn imagined a sword that he planned to use to blast a hole in the wall. However, Finn never got to use it because he thought about a shark trying to bite off his face and unintentionally changed the sword's blade into one.
