The lower disc* is ground for a quality of cutting comparable to pruning scissors
A circular disc with ground edge on one of the modules facing a toothed disc of the other modules provides a clean cut with splitting of the stems.
The cutting effect of the disc prevents the pinching of wood, a common phenomenon in shearing cuts.
A particular configuration of this equipment ensures the respect of the trellis (stakes and wires).
