Light weight professional-grade aluminum telescoping pole saw-the pole saw of choice by professionals. The aluminum alloy extension poles are oval shaped, providing precise control over the direction of the blade (especially important for high cutting) thus reducing bending to the minimum. The base pole has a pole-end shock absorber and comfortable rubberized overgrip. The 13-inch impulse-hardened curved blade utilizes proprietary Silky MIRAI-ME (Smooth Cutting) Technology-The Teeth of the Future! The precision-ground, razor-sharp teeth with four cutting angles provide fast, clean and extremely smooth cutting action. The taper-ground profile reduces drag and directs more usable energy to the cutting edge. It is ideal for pruning branches at higher position without ever climbing a ladder. Black rigid-plastic blade cover is included. To allow effective use of ZUBAT pole saws, two locking systems are incorporated to assure structural rigidity of the extended poles: 1) locking pins/buttons-the primary pole locking mechanism; and 2) friction clamps-the secondary pole locking mechanism. The two systems are designed to work together. This dual locking system allows 100% of the effort at the handle to be effectively transferred to the blade up to 21 feet away. Spring-loaded locking buttons allow multiple length adjustments and safety friction clamps hold the extensions firmly in place.
