Silky Saws ST-797-39-A Sentei & Hayauchi Pole Saw 390MM 15.35″ Replacement Blade

The Silky Saws ST-797-39-A is an OEM 390 mm (15.35″) replacement blade for Silky’s Professional Series HAYAUCHI pole saws and the Notch Sentei pole saw. Built for fast pruning with control, it uses Silky’s aggressive XL tooth geometry at 5.5 teeth per inch (≈6 per 30 mm) to clear fibers quickly while leaving a smooth finish that limits tear-out. The blade is hard chrome plated to resist rust and shed sap, keeping strokes clean in palms, evergreens, and hardwoods. With a 1.5 mm blade thickness, the kerf stays efficient for overhead cuts, and the bolt pattern is sized for a direct fit to the HAYAUCHI and Sentei heads. Crews can expect confident performance on branches up to the recommended 7.7″ diameter, making this a reliable choice for arborists, landscapers, municipalities, and facility maintenance teams who need consistent pruning speed and predictable control from a long-reach pruning saw.
