These Professional Anvil Aluminium Secateurs are ideal for tough. woody and general pruning. helping to reduce strain on the wrist when cutting older. thicker stems. The blade closes against a softer metal on the lower jaw which avoids unnecessary stress on the hand. This does not produce such a clean cut as bypass secateurs. but this is not so important on older growth.These robust pruners have ergonomically designed handles which have smooth plastic inserts and a thumb rest for safety. They have an integrated spring mechanism. easy to use locking mechanism and a non-stick coated blade which has been designed to prevent over-extension of the hand. These pruners can cut through stems up to 25mm thick and the anvil block is fully replaceable. A wrist strap is included for ease of ease and storage.Technical Specification:Blades: Anvil Cutting diameter: 25 mm Exchangeable blade: Replaceable Anvil Block Hand strap: YesWarranty: 10 Years
