Liturgical comb

A liturgical comb is a decorated comb used ceremonially in both Catholic and Orthodox Christianity during the Middle Ages, and in Byzantine Rite to this day.

[1] The exact use of liturgical combs during the Middle Ages remains unclear.

They may have been used in the ceremony accompanying the consecration of a bishop,[2] or before[1] or during the celebration of Mass.

[2][3] Liturgical combs are also known to have been venerated as relics of saints.

So for example were liturgical combs from the 9th and 10th centuries made from a single piece of material (often ivory) and had teeth on both sides, while ordinary, secular combs usually were made in several parts and had teeth on only one side.
