Lawnmower Blades
The hardest part about sharpening a lawnmower blade is detaching the blade safely from your lawnmower. Once the blade is safely removed and held in a vise, a good file is all you need to add an edge to the blade.
Just remember to make sure that you are sharpening the right side of the blade! When detached, it can sometimes be difficult to tell which way the sharpest edge is facing.
