Abstract
A yard tool blade is provided with a distal edge to dig a work material, with a surface to support the work material and an adaptor at a proximal end for receipt of a handle. The distal edge is sharpened to an angle within a tolerance of forty to fifty degrees for a reduced thickness to cut the work material. A method for manufacturing the yard tool blade forms a yard tool blade blank. A cutting edge is machined on a distal edge of the yard tool blade blank. The yard tool blade blank is formed into a shaped yard tool blade. The shaped yard tool blade is heat treated after the cutting edge is machined on the distal edge.
