Sizing Notes

This sharpener accommodates most standard residential and commercial lawn mower blades. Before purchasing, confirm your blade dimensions fall within the supported range: up to 30" long, up to 0.28" thick, and between 2.76" and 5.51" wide. If you are unsure, check your mower's manual or measure the blade directly.

The angle scale is clearly marked and easy to read, letting you dial in the exact sharpening angle your blade requires. The ball-bearing guide arm glides smoothly across the blade surface, ensuring a consistent bevel from tip to tip.

Four included adapter pins ensure a secure fit with most angle grinders, while the four holder bars clamp the blade firmly in place during operation, reducing vibration and improving sharpening accuracy.

Whether you are sharpening a standard residential mower blade or a wider commercial cutting blade, this tool handles the job with minimal setup. Attach it to your angle grinder, set your angle, and sharpen in minutes.
