A great gift for guys! This is the elegant brass version of the Boxing Bell that worked for Muhammad Ali in many a prize fight, it worked for the NY Stock Exchange for decades to start and end their days, and it currently works in mines around the globe. Not only will it work for you, but it will look oh so good while doing it! The gong itself and the mechanical lever action are made of brass. The base is steel with black powder coating.
