The Corona RazorTOOTH pruning saw features a 13-inch curved blade designed for cleaner and faster cutting of medium to large branches, sawing through green or dry wood with ease. The curved design puts more teeth into the branch for faster cutting, giving you a 10-inch blade cut on the pull stroke. The blade is made of a tempered steel alloy to reduce friction and resist rust; the whetstone-ground, impulse-hardened razor teeth are sharpened on 3 sides to plane through wood twice as fast as conventional teeth. The pistol-grip handle with cushion covering is built for comfort and control. Focused Impulse hardening process on blade teeth maintains tooth sharpness after multiple cuts without adding brittleness to overall blade. Hard chrome layer is added to the blade which reduces friction during the cut for less effort and provides a rust preventative layer for longer life.
