The Doorknob Grasper (ドアノブグラスパー) was an obstacle, firstly introduced as the second obstacle in SASUKE 25.

Directly following the Roulette Cylinder, the Doorknob Grasper consists of four knobs protruding from a wall. The competitor must transfer from the cylinder to the first knob and so on. The knobs turn, making it difficult to transfer to the next knob unless turned to stay in place, wasting grip strength.

Only two competitors (both Americans) have failed this obstacle: Brian Orosco and Paul Kasemir. Then, the obstacle was removed after two tournaments.
