The is the transformation device of Kamen Rider Sasword, modeled after a mid-length katana with a straight blade. By placing the Sasword Zecter onto the back of the blade's length, Tsurugi Kamishiro can transform into Kamen Rider Sasword. The Sasword Yaiver also acts as his personal weapon, enabling him to perform the Rider Slash attack, during which the blade secretes a potent poison. It was later destroyed by Soji Tendo's Rider Kick. 
When not in use, the Sasword Yaiver can be mounted onto Sasword's left leg.
