This bypass style pruner features fully hardened, precision-ground high carbon Sk-5 steel blades that stay sharp even after heavy usage. The Teflon coating and sap groove design reduce friction, prevent the blade from gumming up with sap and debris, and help resist rust and corrosion. The pruner features an easy-open control switch for ease and comfort of use. An integrated sap groove captures sticky fluids, and the non-slip grips reduce stress on hands and wrists, making pruning tasks more comfortable. This bypass pruner is perfect for cutting stems and branches up to 3/4" in diameter.
