Professional double blade shears with an interchangeable cutting unit.The steel blade, made with high percentage carbon,  is hot-forged. The traditional grinding face with its flat back is ideal for close and precise cut that prevent bark scarring or the creation of new sprouts. The branch blocking plate speeds up pruning operations. These pruners are ideal for fruit trees. The universal grip of the shears allows both right-handed and left-handed operators to use them. The handles made of light aluminum alloy are hot-forged. This system allows Castellari to provide a lifetime guarantee against breakage. The surface anodizing treatment makes the pruner more resistant over time. The surface is then covered with non-toxic slip resistant material. These pruners are completely interchangeable and adjustable, just like all manual pruning tools.
