The ratchet action of this pruner multiplies the the pressure applied as the toggle advances the blade progressively through the branch. Only light pressure is required. The curved anvil helps to trap branches. Constructed from fibreglass for lightness and a cushioned handle for comfort. The sqeeze/release technique of ratchet cutting reduces pressure required by up to one third and is extremely beneficial for anybody with a weak grip or suffering from RSI, arthritis and related conditions. Great also for prolonged use.
