While you can use any type of cocktail shaker with a Boston shaker being an especially popular option, I highly recommend a cocktail shaker with a rubber seal for drinks that require a dry shake. Cold ice is what helps seal most metal cocktail shakers, so the dry shake can get a little messy, and you don’t want to lose that delicious whiskey. Once I switched to a cocktail shaker with a rubber seal, it made the dry shake so much cleaner and easier.
