We cover everything you need to know to successfully sharpen lawn mower blades using a file.

Lawn mower blades are only sharp on one side (unlike, say, a knife). So be sure to only sharpen the chiseled side. As Jack says in the video, it’s similar to a chisel that you would use for woodworking.

Using your flat file, begin filing, following the contour of the blade. File into the direction of the cut (see the video for a demonstration of this). You’ll notice that the blade will start to become silver. If there are any detents in the blade (which there usually are for mulching purposes), you can rotate your file.

Continue to file until the blade is sharp.
