Abstract: A system for treating material of a cutting element may include a method, and the method may include providing a piece of material to form a blank for the cutting element, and applying a cladding material to at least a portion of the blank utilizing a laser to bond a cladding powder to the exterior surface of the blank. The application may include selecting and utilizing a power level of the laser and a rate of movement of the spot of the laser across the exterior surface which is effective to form a stratum of martensite in the substrate of the material below the exterior surface and the cladding material bonded to the exterior surface. The method may further include removing a portion of the cladded blank to form a cutting edge with a portion of the stratum of martensite exposed at the cutting edge.

Abstract: A knife with a serrated cutting edge may include a plate having a leading edge forming a plurality of teeth seats arranged in a stepped configuration, with each of the plurality of teeth seats. The knife may also include a plurality of elongate cutting elements each affixed to one of the teeth seats formed by the leading edge. The cutting elements may form a portion of the serrated cutting edge, and each may have a top surface and a bottom surface. The cutting edge may be on the top surface and the bottom surface may be affixed to one of the teeth seats. The serrated cutting edge has a plurality of primary serrations and a plurality of secondary serrations, with each of the cutting elements forming at least one of the primary serrations and at least one of the secondary serrations.
