What is a "nutcracker"?

A nutcracker is a hand tool designed specifically for cracking the shells of nuts to access the edible kernel inside. It typically consists of two hinged arms, with one end containing a ridged or serrated surface for gripping the nut, and the other end featuring a lever or handle for applying pressure to crack the shell. Nutcrackers come in various sizes and designs, ranging from simple handheld models to larger, more decorative versions for tabletop use. They may be made from materials such as metal, wood, or plastic, with some featuring decorative embellishments or intricate patterns.
