FIELD: technological processes.

SUBSTANCE: scissors comprise an upper movable blade with a base attached to a slide connected to a piston located in a cylinder, at the end of which the chamber is located. Scissors are equipped with the following parts attached to the chamber: a recharging device with a shutter mechanism, that includes a trigger and firing mechanism and an extractor, two lower fixed stops, rigidly connected to each other and arranged parallel to each other at a distance greater than the width of the base of the upper blade, a guide with lower stops attached to its one part and with a cylinder attached to the other part, and a bridge connecting these parts of the guide. Upper movable blade is designed in the form of a wedge, on the lower generatrix of which protrusions are made, faceted in planes intersecting the generatrix of the wedge face at angles which apex is located in the plane of blade motion to the base of the upper blade. Scissors recharging device can contain a holder with pyro-cartridges stacked in it with the possibility of alternately supplying the pyro-cartridges to the impact zone of the trigger and firing mechanism.
