This nutcracker has 2 practical functions. The tongs can crack open a variety of different nuts, including walnuts, Brazil nuts and almonds. It can also be used as a champagne bottle opener. The grooves on the inside of the gripper hold the nuts securely so they do not fall out or slip away. This is also ideal for opening champagne bottles. Whether for birthdays, winter holidays or a regular day in the kitchen, this practical 2-in-1 nutcracker can always come in handy.
