the.com/worry beads

means A string of beads fingered in a slow rolling rhythm, not for prayer but purely to pass time or soothe restlessness.

from English borrows the idea from Greek 'komboloi,' strings of beads descended from prayer-bead traditions found across the Eastern Mediterranean and Middle East (like the Muslim misbaha), but stripped of religious counting purpose and kept purely for the pleasure of the click and the occupied hands — the word 'worry' got attached in the West simply to describe what the fidgeting seemed to be for.
