The Wolf Garten RS4000 Anvil Secateurs are ideal for tough, woody and general pruning. Anvil blades help to rude the strain on the wrist when cutting any older, thicker stems. The blade will close against a soft metal on the lower jaw, avoiding unnecessary stress on the hand. Whilst the cut may not be as clean as bypass secateurs, this is not as important when cutting old growth. These robust pruners are suitable for regular use and ideal for a larger sized hand. The ergonomically designed handles have an integrated thumb rest for safety. They have an internal spring mechanism and a central locking mechanism. The non-stick blade can cut through stems up to 25mm thick and the upper blade is fully replaceable.
