A more thorough explanation:

Definition: A burglary tool is an object or tool that is designed to help someone commit a burglary. In some places, it is illegal to possess a burglary tool if the person intends to use it to commit a burglary.

• A crowbar
• A lock pick set
• A screwdriver

These examples are all tools that could be used to break into a building or home. If someone is caught with these tools and they are intending to use them to commit a burglary, they could be charged with a crime.
