Which type of hydraulic tool features at least one movable blade for cutting or shearing material?

The cutter is specifically designed to feature at least one movable blade for the purpose of cutting or shearing materials. This type of hydraulic tool is commonly utilized in emergency situations, such as vehicle extrication, where precision cutting is required to access trapped victims or to dismantle wreckage safely. The movable blade is particularly important because it allows for the effective slicing through hard materials, such as metal or reinforced structures, that would be impossible to achieve with tools that do not have this capability.

In contrast, the spreader tool is designed to create space by pushing apart objects rather than cutting them. An extension ram provides linear force to push or pull objects but does not incorporate any cutting mechanism. The combination tool, while versatile and capable of performing both spreading and cutting functions, integrates the features of both a spreader and a cutter but does not specifically define a single blade mechanism as its primary function.
