1. A method for forming a sharpened cutting tool from an intermediate cutting tool, the intermediate cutting tool having a ground cutting tip that comprises a planar face and a sharpened cutting edge at a distal end of the planar face, the ground cutting tip being relieved on a side and an end that cooperate with the planar face to define the sharpened cutting edge, the method comprising:
masking the intermediate cutting tool such that a first predetermined portion of the planar face is exposed and a second predetermined portion of the planar face is not exposed, the exposed portion of the planar face including the sharpened cutting edge and including at least portions of the end and the side that cooperate to define the cutting edge; and depositing a wear-resistant material onto the exposed portion of the planar face of the intermediate cutting tool to form the sharpened cutting tool.
