A reliable replacement for Honda’s 21‑inch (53 cm) upper cutter blade, this set includes the blade and a handy sharpener attachment—perfect for keeping your mower performing at its best.
Why it works
The blade is forged from solid steel and finished with a durable powder‑coat that resists rust and weathering. Its dual‑curved design lifts grass blades into the airflow, delivering a clean, even cut even on tall or damp turf. The shape also helps eject clippings efficiently, making bagging or mulching smoother.
