The Browne 57505 is a 15 oz., stainless steel cocktail shaker, otherwise known as a Boston shaker. Plenty of cocktails require the drink to be shaken, and that's where cocktail shakers come in. They're an essential part of any bartender's gear.

As this cocktail shaker is only 15 oz., it's pretty small. Something of this size would be great for martinis, which only average around 4 oz. This cocktail shaker can also be paired with a larger shaker and be used as a cheater.
