The Devilish Blade (デビリッシュブレード) is the sword that Kogu uses in Dragon Ball Z: Bojack Unbound.
It has a triangular guard, a blue hilt, and a thin blade similar to a rapier.
Kogu uses this sword during his battle with Future Trunks, who scolds Kogu for having the sword on him as the Intergalactic World Tournament specifically forbids the use of weapons. The Devilish Blade is blocked by Future Trunks when he turns Super Saiyan. The sword then breaks, and Future Trunks proceeds to kill Kogu with a fist through the chest.
