The Rousing Sword Blay Rouzer (醒剣ブレイラウザー Seiken Burei Rauzā) is Kamen Rider Blade’s primary armament. It's a hi-tech saber which serves as a weapon for combat and storage unit for Rouze Cards, including Proper Blanks. With built-in 'rousing' technology, this enables Blade to "rouse" the sealed Undead's power to utilize personally. After activating Jack Form, the Blay Rouzer gains an enhancement in the form of a blade extension. Its extended length aside, all of the standard features and functions remain intact, although its AP Cache has been largely expanded.
