Which type of rescue tool combines several functions, including cutting and spreading?

The combination tool is specifically designed for vehicle rescue operations and effectively merges multiple functions into a single device. In situations where access is crucial, this tool can cut through metal and other materials while also spreading apart sections of a vehicle to create space for rescue operations. This multi-functionality makes it invaluable in emergency situations, allowing rescuers to perform various tasks quickly and efficiently without needing to switch between multiple tools.

In contrast, the ram is primarily used for pushing or forcing apart materials rather than cutting, while the pneumatic cutter is dedicated solely to cutting and does not include spreading capabilities. The electric saw is also designed for cutting but lacks the capability to spread or manipulate materials as needed in rescue scenarios. This versatility and efficiency in handling multiple aspects of rescue make the combination tool the best choice for the question.
