Gavel

A gavel is a small ceremonial mallet 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. 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.
