What is the mallet thing that a judge bangs while he says Order in the Court?

The mallet used by a judge is called a gavel. It serves as a tool to call attention, maintain order, and signify the beginning or end of court proceedings. When a judge says "Order in the Court," they use the gavel to emphasize the importance of maintaining decorum in the courtroom. Its sound serves as a cue for everyone present to focus and respect the proceedings.
