Zenport Pruner Blade QZ407-B Replacement Cutting Blade for Zenport QZ408 and QZ407 Professional Pruner. This classic pruner for Smaller Hands has a comfortable, light, sturdy handle made of forged aluminum. The blade is made of high-quality hardened steel, which allows clean, precise cuts. The sap groove prevents the blade sticking when cutting “sappy” wood. It saves time and makes pruning easier by removing sap and debris after each cut. Pruner is easily adjustable. Hand and wrist protection and optimization of the force exerted are provided by the angled head, the ideal shape of the handles, and the cushion-shock absorber – non-slip coating. Compact cutting power for smaller hands. Revolving handle prevents blisters and reduces hand fatigue.
