Choosing the right shaker is familiarity and opinion, and you may become comfortable with any type you choose. If your concern is simply ease of operation, a three piece shaker may be best. For experienced mixers who are looking for speed, a two piece system of capping a smaller tin or mixing glass is often used, as is simply using a single tin for stirring and a wire strainer to separate the ice. 2-piece shakers are also offered as a set, and for many look is a large consideration. If you want a little personality and ease of grip, you may want to see a vinyl-coated shaker. Picking metal or plastic is another consideration when budgets and showmanship of both professionals and beginners are important factors.
