A kanabō is a big stick that Japanese people used in ancient times to fight off enemies. It looks like a big, thick baseball bat with spikes. People would hold it with two hands and swing it really hard to hit their enemies. It was often used by samurais, who were like sword-wielding knights. The spikes on the kanabō were meant to make the stick more deadly, as they could pierce through the armor of their enemies. The kanabō was also sometimes used as a symbol of power and authority by samurais, who would carry it around as a way of showing off their strength and status. It's like having a really big stick that you can use to defend yourself or show others how strong you are.
