A nutcracker is a simple tool designed to crack open hard shells of nuts, such as walnuts and hazelnuts. Typically made of metal or wood, it features two levers that create pressure on the nut when squeezed together. This allows the user to access the edible kernel inside without damaging it. Nutcrackers come in various designs, from traditional hand-held models to more elaborate mechanical versions. Some are shaped like animals or characters, adding a decorative touch to their functionality. The tool is often used during holiday seasons, especially in connection with festive treats and celebrations involving Christmas and New Year's.
