After you’ve gone over the entire blade with the file, use the steel wool to remove any burrs or debris from the sharpened edge. When you’re finished, wipe down the blades with a clean cloth.

Step Four: Reattach the Guard

Now that you’ve finished sharpening the blades on your Black and Decker hedge trimmer, it’s time to reattach the guard. First, make sure that the trimmer is turned off and the blades are not moving.
