Square Shovels

Sharpening the top edge enables the shovel's back to lie flat on the surface, getting all the material into it (e.g., mulch sitting on a concrete drive, or gravel in the bed of your truck).

Sharpen the inside edge using an angle grinder with a 120 grit flap disc. A metal grinding wheel may be needed for shaping the edge if it is in bad shape.

General Guidelines
If the original angle is different, it is best to match that.
