After retrieving the Birthstone from Gatto's Keep, Jim brings it to Vendel, who teaches him how to cleave the stone in order to unlock its power. After doing so, Jim places it inside his amulet, and instantly comes into possession of two glaives.
The glaives look like two small daggers found in his outer thigh area. Like his armor, they share the distinct blue and silver color pattern, with a short curved blade. They interlock in the middle.
The glaives turn red and black when Jim unlocks his Eclipse Armor.
They can be joined to form a small double-scythe-like weapon. Like boomerangs, these daggers will return to the Trollhunter after he throws it.
While fighting Angor Rot in "Where Is My Mind?", Jim also realizes that Angor is unable to use the glaives like when he pinches his sword from him, and that he can pull the dislodged glaives in the wall back to him. He also learns that he can connect the glaives in mid-air.
|Appearances in the Trilogy|
- The weapons being called glaives is a misnomer; glaives are actually a European pole arm weapon, not handheld knives. A similar occurrence happened in the Blade movies where the titular character wielded similar weapons that were likewise called glaives.
- However, glaives are a type of modern foldable shuriken-like pocket knives, which are also throwing weapons.
