Twist the shaft and the two nuts slide apart, one left and one right, guided by grooves cut into the same piece. The dual-direction movement feels like a small magic trick every time you do it.
Hold it between your fingers and let your hands find the rhythm. The motion is smooth and repetitive in a way that makes you lose track of time, then you notice you have been spinning it for minutes.
Keep it nearby. Watching the nuts travel in opposite directions along the grooves has a quiet hypnotic pull.
