Silky Saw Blade 420-6.5 for Stick Saw. The 420 mm long curved blade of the Hayate features Silky's unique Mirai-Me teeth. These laser-cut teeth, spaced 1.7 mm apart, ensure that good wood is removed, allowing you to easily and quickly cut through the thickest branches. The saw blade is chrome-plated, flexible, and only the razor-sharp teeth are impulse-hardened. With the optional lower blade (Art. No. 1541142), you can cut into the bark, preventing it from tearing along the trunk when the branch falls. The upper blade prevents the saw from slipping out of the cut. With this upper blade, you can easily cut branches from the trunk or remove small (dead) branches from the tree.
