On Lawn Mower blades, sharpen the upper side of the blade's leading edge. The areas to be sharpened are highlighted in red. (Click on the picture to see a larger version.)
On Lawn Edger blades, sharpen the side of the blade which is the leading edge. The areas to be sharpened are highlighted in red. (Click on the picture to see a larger version.)
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.
If the original angle is different, it is best to match that.
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.
