Ballistic knife

Okay kiddo, a ballistic knife is a type of knife that can shoot out its blade like a tiny missile! It's kind of like a toy rocket that you can control with your hand.

But why would someone need a knife that can shoot out like that?

Well, people who use ballistic knives usually use them for hunting or self-defense. Sometimes they need to throw their knife really far to hit a target or to protect themselves from a dangerous animal or person.

It's not a toy, though, because it can be really dangerous if people don't know how to use it. That's why it's illegal in many places because it's too risky for people to have something like that. So, it's important to always listen to grown-ups and not play with knives or dangerous weapons.
