But to bring a sword

A sword is a special tool that people used a long time ago to protect themselves from other people who wanted to hurt them. It's like a really big, fancy knife that is made of strong metal so it can be used for a long time.

People used to bring swords with them whenever they went outside to make sure they were safe from any bad guys who might try to hurt them. However, nowadays, we don't really need to use swords anymore, because we have other ways to stay safe, like calling the police or using self-defense techniques.

So, in summary, bringing a sword was important a long time ago when people needed to protect themselves, but now we have different ways to stay safe.
