Turning the beads
In Greek and Cypriot life the komboloi is used to relax and pass the time, by people trying to smoke less, and as a mark of standing, above all when the beads are silver or amber; some keep one as an amulet against misfortune. A Greek komboloi usually has an odd number of beads, often 17, 19 or 23, with a fixed head bead called the papas, ‘priest’, a shield that keeps the two threads apart, and a tassel. A quiet way to use it is to tip the beads over one at a time, so that each falls and clicks against the shield. The word is traced to komboskini, the Greek prayer rope, but worry beads have no religious purpose.
To verify: These uses and bead counts against a published study: the encyclopedia article we used relies mainly on a Greek collector’s book (Tasos Thomaidis, 2001) and asks for better sources
