A cutting tool of the scissor type includes a pruning head with fixed counter-blade and movable blade operated by a first cord sliding on sheaves. The pruning head is connected to a telescopic extension pole with two side shells that enclose a trolley carrying two trolley sheaves and a fixed sleeve that form a tackle housed within the shells. The telescopic pole is comprised of two pipes, one of which slides inside the other, which are provided with grooves, a sliding cap, a pipe-clamp and a handle, which define a path of a second cord that allows the telescopic lengthening of the pole while maintaining the tension of the cord and maintaining the position of the handle.
