A gavel is a small ceremonial mallet commonly made of hardwood, typically fashioned with a handle and often struck against a sound block to enhance its sounding qualities. It is a symbol of the authority and right to act officially in the capacity of a chair or presiding officer^[1]. It is used to call for attention or to punctuate rulings and proclamations. It is customarily struck to indicate the opening (call to order) and closing (adjournment) of proceedings, giving rise to the phrase gavel-to-gavel to describe the entirety of a meeting or session. Gavels are also used by auctioneers.

By metonymy, the gavel represents the entire judiciary system, especially of judgeship; to bring down the gavel means to enforce or compel with the power of a court. It also represents the authority of presiding officers; thus the expression passing the gavel signifies an orderly succession from one chair to another.
