|Finn's original gold sword|
|Introduced in||"Slumber Party Panic"|
These are the swords that Finn had mainly used throughout the series.
Finn's golden sword of battle
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."
Root swordIn "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 of Cuteness," and in "Jake vs. Me-Mow." He keeps it in a makeshift pocket on his backpack.

These are the swords Finn has kept at the Tree Fort.
Steel swordAs of the episode "Still," Finn has a new steel sword similar to his original gold sword. The pommel has a purple gemstone with a tiny pink gemstone slit in the center. The hilt has good-condition leather grips on it. The sword itself is in very good condition.
Pink jewel sword
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.
KatanasFinn 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 dead
Finn wields the sword of the dead to defeat Marceline's father in "It Came from the Nightosphere." 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.

Dagger of chilled glass
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 posses magical powers.
- The sword in the Adventure Time logo has never been used, other than in the promo video. However, a version of it was imagined by Finn while dreaming in "King Worm."
- The yellow twisted dagger Finn used looks similar to Me-Mow's dagger.
- Fionna (the gender swapped version of Finn) has a Crystal sword.
- The Tree Fort has several swords strewn around it, though Finn and Jake never use these.
- In the game Adventure Time: Hey Ice King! Why’d you steal our garbage?! Collectors Edition there is a stylus resembling Finn's golden sword.
