ABSTRACT:
A hand-held tool has cutter blades actuated by a power wedge on a piston rod in an hydraulic cylinder. The hydraulic cylinder is powered by a compressed air supply through stationary apparatus containing an air-hydraulic pressure intensifier apart from the tool and connected therewith through a hydraulic line. The power wedge has inclined ramps at relatively steep angles of inclination to start closing of the blades quickly, and ramps at less steep angles to increase the force applied to the blades in cutting. An adjusting wedge stops the advance of the power wedge so that the blades do not strike each other. The tool may have an elongated rear extension with a pistol grip handle.
