The HAYAUCHI is a 4-RETSUME saw with 6.5 teeth/30mm and blade cutting length 390mm. The upper sickle is used to cut vines; the lower sickle to undercut bark allowing a clean cut without damaging the tree. The aluminum alloy extension pole is race-track shaped, giving precise control to the direction of the saw blade (this is especially important for high cutting) and also giving strength and rigidity to the pole, reducing bending to the minimum. Push buttons allow multiple length adjustments and safety clamps hold the extensions firmly in place. A rubber hand-grip ensures good hold and control. The blade is adjustable to 2 angles for lower or higher cutting. Sheath included. 2 Extension Model Featured - See below for the 3 extension 21' model.
