Why do candy canes always have the J shape?

1. Religious Symbolism
One of the primary reasons the J shape became standardized for candy canes is attributed to its religious symbolism. The shape of the candy cane can be interpreted as a representation of the staff of the 'Good Shepherd', a title often given to Jesus Christ, reflecting the shepherds who visited the infant Jesus during the Nativity story. When flipped, the cane also resembles the letter 'J' for Jesus, providing a subtle nod to the religious origins of Christmas. These symbolic connections were thought to reinforce the religious significance of Christmas and teach children about the faith.
2. Practicality and Handling
Beyond symbolism, the J shape of candy canes is also incredibly practical. The curved end serves as a perfect handle for holding the candy without getting sticky fingers, a benefit appreciated by children and parents alike. Additionally, the hooked shape makes it easy to hang candy canes on Christmas trees as festive decorations—an increasingly popular custom through the 18th and 19th centuries which continues to this day.
