ELI5: Explain Like I'm 5

Blade

Okay, imagining you're five years old, a blade is a sharp and flat piece of metal or other strong material that can cut things like paper or even fruits and vegetables. Think about a knife that you might use to spread butter on bread or a sword that a knight might use to fight bad guys. It's important to be very careful when handling blades because they can be dangerous if someone is not trained to use them properly.
