Lawn Mower and Lawn Edger Blades  

When the world wearies and society fails to satisfy, there is always the garden.

Minnie Aumonier

On Lawn Mower blades, sharpen the upper side of the blade's leading edge. The areas to be sharpened are highlighted in red.

On Lawn Edger blades, sharpen the side of the blade which is the leading edge. The areas to be sharpened are highlighted in red.

Care must be taken to ensure the blade remains balanced (i.e., ensuring that the removal of metal during the sharpening is equal on both sides). For this reason (and many others), it is highly recommended to perform the sharpening of the blade after removing it from the mower.

General Guidelines
α Notes Recommended
Tormek Jig
30° If using a Tormek to sharpen this blade, the SVM-45 Knife Jig can be used, but I'd recommend using the SVD-110 Tool Rest.

The Lee Valley Rotary Mower Sharpener sharpens blades at 25°.
