The grass sword is Finn's replacement for Joshua's broken demon blood sword. He buys it from the Grassy Wizard, who cursed the sword so it will bond itself to its owner, but Finn instead accepts the sword as his own, allowing him to better control it. When not in use, the sword wraps itself around Finn's arm in the form of grass wristband.
Abilities
Throughout "Blade of Grass," Finn is able to use the sword with extreme precision. This is to the point that he can quickly carve his face into various objects. Also, when Finn flicks the sword, it whirls in deadly circles like a helicopter blade.
The grass sword also possesses abilities resulting from its curse. The sword incessantly follows Finn; when Finn tries to cast it away, he soon finds himself holding the sword again.
When Finn accepts that the sword is cursed, he becomes able to control its material state—he can toggle between wearing the sword around his right arm as a bracelet and extending it as a sword.
As of "Rattleballs," once Finn takes control of the grass sword, he has trouble controlling its extreme precision. The blade can also regenerate itself when cut off.
Origin
The grass sword first appears in the episode "Blade of Grass." When Finn struggles to fight off monsters with the broken demon blood sword, Jake tells him to get a new sword. They go shopping in town, where Jake leads Finn into the Grassy Wizard's teepee as he had heard it was "the place to get swords." Finn buys the grass sword for three dollars. As he leaves the teepee, the Grassy Wizard quickly whispers, "Remember, no take-backs."
Curse
Tree Trunks is the first to suspect that the grass sword is cursed. When Finn slices an apple for her, she observes, "Something is terribly wrong with that sword... That apple slicing is too perfect. Demonically perfect. That sword is cursed!"
Later that night, Finn stows the sword in a box before going to sleep. He dreams that he is standing in a grassy field; a sword appears out of the grass, dissolves into grass, and reappears in his hand. But soon, the grass spreads to the rest of Finn's body, and he too dissolves in the wind. He awakens to find that the sword has somehow made its way into his sleeping bag, and is now wrapping itself around Finn's right arm. Finn runs into the forest, tears off the sword, and kicks it into a river. But when he goes to the bathroom the next morning, he finds the sword inside, dripping wet. Jake tries to stop the sword from latching onto Finn by wrapping his apron around its hilt and sheathing it with a baguette.
Finn and Jake try to return the sword the next day, but discover that the Grassy Wizard's teepee has vanished. With the help of Choose Goose, they track down the Grassy Wizard to his shack, where he unsuccessfully attempts to fend them off. Finn demands that he lift the curse, but the Grassy Wizard replies, "Never! You have no power over me, young fool! The grass sword will be part of you for all eternity!"
After considering the sword's effectiveness, Finn realizes, "You know what? I think I'm cool with that." His acceptance of the curse allows him to control the sword's powers.
Trivia
Cultural References
- In design, the grass sword resembles a Japanese tachi. The tachi is a type of early fifteenth-century sword used by nobles, landlords and Samurai. The tachi is also a predecessor of the well-known katana.
- Cursed weaponry that cannot be unequipped is a common video game theme.
- In "The Red Throne," Finn deploys his grass sword while his fireproof suit is still on, making it go right through the suit, though when he undeploys it, it wraps around the suit's arm instead of his own. This is either an ability of the sword or an error in the episode.
Storyline Analysis
- The cursed grass blade, which wraps itself around Finn's right arm, may prefigure the loss of Finn's right arm, which is absent in all of Finn's alternate reality portrayals.
