The invention pertains to a process for manufacturing a blade of a cutting tool, in particular, a knife. In order to create a process with which influence is to be exerted in a targeted manner on the technological material properties of the blade and material chipping to be avoided, as well as permitting economical manufacturing, a process is proposed with the invention that is characterized in that the blade base material is laser-treated in a first process step along a curve contour determined by the later edge of the blade and, in a second process step, the edge of the blade is formed, in particular, cut to shape, along the curve contour determined by the later blade form inside the laser-treated area, or the blade base material is machined in a first process step by punching or trimming to form the later edge, subsequently the laser treatment is performed in a second process step on the narrow side forming the later edge and finally, in a third process step, the blade is formed, in particular, ground, inside the laser-treated area.
