Then find the perfect angle of sharpening by placing the grinder over the blade’s edge. Use medium pressure and start sharpening by moving the drilling machine forward and backward. Only a few strokes will do the job for you. You can point both the edges in the same process.
If you use an angle grinder, you need to use a flap disc. Alignment needs to be done manually. After that, move the angle grinder slowly, and all your rough spots will get smoothened. After finishing the process on one side, you need to repeat the same thing on the other side.
A person planning to sharpen the blades of a lawnmower needs to remember a few things while sharpening the blades. Do not overheat the edges of the lawnmower blade. When overheating, dunk it in a bucket full of cold water. Over sharpening the lawnmower blade is also harmful as a razor-sharp blade can cause a lot of harm to the user.

In case of a disbalance, the consequence will be distributed unevenly, and that will cause damage to several parts of the lawnmower along with the blade. You can check whether one side is heavier than the other by hanging a nail on edge. If the blade falls on any one of the sides, it will indicate that the side is more severe than the other one. In case you are facing a situation like this, use a metal file or a grinder to remove excess metal, which will, in turn, reduce the weight of the blade and will make it balanced.
