A redesign of the popular model 610 saw, the blade design was improved for faster, smother cutting and made much longer for cutting even larger branches. The new turbo-cut blade leaves wood as smooth as if it were planed. Unlike conventional saw teeth which are filed and alternately bent opposite directions, the turbo-cut saw blade is taper ground and each tooth is honed to precise knife-edge sharpness. The hard-chrome plating prevents rust. Resins will not cling to the blade and green wood will not clog the teeth. For complete safety and easier cutting, the saw cuts on the pull stroke. The belt-attached sheath provides quick draw of the saw for immediate, one-hand use.
