Professional straight-edge lopper suitable for pruning any plant. The lever-assisted movement with “S” tie-rod, allows cutting branches up to 45 mm in diameter, decreasing the effort and without recoil on the operator. The special construction of these branch cutters provide a better handle opening/cutting capability ratio. The handles are made of extruded anodized aluminum with an oval cross-section, capable of withstanding large stresses. The blade and “S” tie rod (with bushing), made of high-carbon steel, are hot forged. The lightweight aluminum counter-blade is hot forged and is guaranteed for life against breakage. Like all hand pruning tools, it is fully interchangeable.
