Grow Tech LA-180LR21 7' Heavy Duty Razor Edge Pruner The blade and unit have been designed to provide the best cutting leverage and durability. This is our recommendation for the hardest long reach pruning jobs. Available in 3 fixed lengths. Drop forged blades provide better cutting leverage and stay sharp longer while hard chrome plating on the blades resists rust and sap. Bigger leaning blade with thicker arm provides extra strength and durability. The pipe has a blind nut in order to firmly secure the new stop screw. A new stronger inner rod at the drum extends the life of the pruner.
