gavel

A gavel is a small ceremonial mallet/hammer commonly made of hardwood, typically fashioned with a handle. It can be used to call for attention or to punctuate rulings and proclamations and is a symbol of the authority and right to act officially in the capacity of a presiding officer. It is often struck against a sound block, a striking surface typically also made of hardwood, to enhance its sounding qualities. It is primarily used in live auctions.

According to tradition, Vice President of the United States John Adams used a gavel as a call to order in the first U.S. Senate in New York in 1789. Since then, it has remained customary to tap the gavel against a lectern or desk to indicate the opening and closing of proceedings and, in the United States, to indicate that a judge's decision is final. Usage differs between cultures, but it is also generally used to keep the meeting itself calm and orderly.
