These are nice heavy duty pruning shears. They are very comfortable to hold. The pruning shears fit in small and medium hands comfortably also. They have anti slip cushioned handle grips and shock absorbing pads. They truly do help in reducing injury and wrist strain. The cutting size diameter on these is 0.8 inches. The blades are made out of high tempered carbon steel titanium. These pruning shears have a wire cutting notch so it cuts small wires without damaging the blades. The shears have micrometric adjustment system that allows you manually adjust the alignment and play of the cutting blade. An added plus on these pruning shears is that they have a sap groove so that sap or other contaminates will not stick to the blades and will keep debris away from the blades.
