Professional double blade pruner with an interchangeable cutting unit.The steel blade, made with high percentage carbon,  is hot-forged and the grinding face that converges to the center of the pruner increases branch penetration. These shears are ideal for use with fruit trees, providing precise and clear cuts that prevent bark scarring or the creation of new sprouts. The universal grip 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.
