KNUCKLES DUSTER® TWO
A comfort grip for the Valve Index® VR controller — sculpted by an automotive surface designer.

KNUCKLES DUSTER® TWO bridges the gap between the virtual world and the Valve Index® controller. Developed with the same A-class surface methodology used for European automotive interiors, the grip wraps the controller in a soft-touch silicone shell — refined geometry, sculpted relief, no rough edges.
Key Features
- Enhanced grip button function — better tactile response under finger pressure
- Thumb rest — natural resting position when not interacting
- Bottom strap guide — keeps the controller strap clean and aligned
- Material: hard-wearing soft-touch silicone, graphite gray
- Fit: medium & large hands
- Pair: Left + Right grip, presented in an elegant package
Calibration Note
For finger-tracking to work with the grip installed, the Valve Index® controller needs to re-calibrate dynamically. Power off the controller first, then install the grip. Power on while holding with the middle, ring, and pinky fingers — let the index finger and thumb hover freely. Drum-fingers a few times until tracking re-locks. If needed, restart the controller and repeat.
