When grinding an axe head, you need to get the angle right. So, before starting the grinder, set the axe head and find the accurate angle. After you’ve found it, keep the axe head a little back from the grinder, and then turn it on. Keep the movement consistent when sweeping it across the grinder. After you finish sharpening one side, flip the axe and repeat the same process with the other side. Ensure to spend the same amount of time on both sides.
