A strainer for cocktail shakers is a bar tool used to strain ice and other solid ingredients from mixed drinks, while pouring the liquid portion of the cocktail into a serving glass. It is made of metal, with a flat, perforated disc that fits over the mouth of the shaker. The strainer is held in place by placing a finger over the small, handle-like protrusion on one side of the disc, while pouring the liquid out through the larger opening on the other side. The perforated disc helps to filter out any small bits of ice or fruit that might be left in the mixture, resulting in a smooth and refined cocktail. The strainer also has a spring around the edge of the disc that helps to hold it securely in place over the shaker, preventing any spills or drips.
