Nutcracker dolls, also known as Christmas nutcrackers, are decorative nutcracker figurines most commonly made to resemble a toy soldier. In German tradition, the dolls are symbols of good luck, frightening away malevolent spirits. While nearly all nutcrackers from before the first half of the 20th century are functional, a significant proportion of modern nutcrackers are primarily decorative, and not able to crack nuts. Nutcrackers are also a part of German folklore, serving as protectors of a house.
