The Engine Blade (エンジンブレード Enjin Burēdo) is Kamen Rider Accel's personal sword weapon. It first appears in episode 19. Through the use of the Engine Memory, Accel can use the Engine Blade's different elemental abilities by pulling the trigger. It also allows Accel to perform two unique Rider Slash Maximum Drive finishers with the Engine Blade through the Engine Memory. Ryu can wield this weapon outside of Accel's transformation, though it is extremely heavy.
