Which tool has two retractable blades?

The tool that features two retractable blades is typically recognized as a utility knife. Utility knives are designed with a blade that can be extended or retracted for safety and convenience, making them versatile for cutting different materials. While a plaster hook is a tool used for handling drywall, it does not generally come with retractable blades but rather has a specific design for lifting and positioning drywall sheets. Multi-tools also have multiple functions and often include various tools, but they do not specifically feature retractable blades as the primary characteristic. Cable cutters are designed primarily for cutting wires or cables and usually have fixed blades that are designed for leverage and strength rather than retractability.
