Abstract: A coating doctor blade having a chamfered face is produced by the steps of forming into a roll a hardened and tempered metal band blank, edge-grinding the blank in the roll, winding off the blank, planing a chamfer surface on one side surface of the blank by moving the blank, in a single pass in the longitudinal direction of the blank, over a single hard metal bit thereby providing a chamfered surface free from scratches and grooves detrimental to the evenness of a coating spread by the resulting doctor blade, and dividing the so-chamfered blank into doctor blades of suitable lengths.
