The Corona 12-foot compound-action tree pruner is a versatile tool that gives you the combined benefits of a saw and bypass pruner for fast, easy pruning; the telescoping fiberglass pole adjusts to precisely the right length for small, medium or larger trees. Pass-thru shearing action drives a blade sharpened on both sides directly through the center of the hook, giving you more even cutting power and resisting the binding common with side-mounted blades. The fully heat-treated, coated cutlery steel blade easily prunes branches up to 1 inch in diameter, while the 15-inch conventional saw blade can be used to remove larger limbs. The pruning head is made of die cast zinc alloy for added durability, and the pruner features a compound-action pulley system that increases your leverage and triples your cutting power. The strong, lightweight fiberglass pole telescopes to 12 feet with an infinitely adjustable twist-lock extender and non-pinching twistlock adjustment. The unique internal stop prevents the inner pole from separating from the outer pole.
