Deciding on the right shaker tin is a personal matter, and you are sure to become comfortable with any type you choose. If your concern is spill-free ease of use, a three piece shaker may be your solution. For experienced bartenders who might be looking for rapid application, a 2-piece system of capping a small shaker or mixing glass is common, as is simply using a single tin for mixing and a wire strainer while pouring. 2-piece shakers can come as a set, and so often having a matching look is a large consideration. If you want a bit of flair and ease of grip, you may want to see a vinyl-coated shaker. Choosing metal or plastic is a factor when budgets and showmanship of both professionals and beginners are important factors.
