What happens here

To sharpen the blade using an angle grinder, secure the lawn mower blade firmly in a vise. Put on safety glasses and ensure a steady grip on the angle grinder. Carefully align the grinding disc with the existing factory angle of the blade. Begin grinding slowly across the cutting edge, maintaining a consistent angle and avoiding digging into the blade. Work evenly along the entire cutting edge until a burr forms on the opposite side. Repeat for the other cutting edge if applicable.

Goal: Restore the cutting edge of the blade using an angle grinder.

What they say

Hide

Main thing that you got to worry about when sharpening lawnmower blades is just maintaining that factory angle. If you have a bunch of nicks and gouges pretty deep, maybe it's time to get some new ones. Important to get your angle set right and then just run slowly across it. You don't want to dig in this way or this way. Another good method that's basically the same as an angle grinder is your bench grinder. Just go ahead and power it on. And same deal here.
