The Abyss Saber (アビスサベル Abisu Seibā) is Kamen Rider Abyss's personal sword weapons, summoned by him when using the Sword Vent card in his Advent Deck. Depending on his preference, he can summon either one or both of the swords for combat use or use one sword in tandem with the Abyssmash gauntlet.
The swords are jagged curved blades with uneven sharp edges made to resemble the teeth of a great white shark.
- In Episodes 6 and 7, Abyss used only one of the pair of Abyss Sabers. However, the Detail of Heroes photobooks and the S.H. Figuarts toy revealed that Abyss can summon a second sword.
