The article describes the designs of disc knives for cutting various materials, discusses the known designs and methods of production of disc knives, their advantages and disadvantages. Solid knives made of tool steel are expensive to manufacture and do not allow efficient use of the material. It is advisable to manufacture disk knives of bimetallic design. A method of manufacturing a disc knife is proposed, including the assembly of a package of blanks with subsequent batch surfacing. The surfacing provides a working layer of tool steel. Heat treatment and grinding of work pieces on a cylindrical surface is carried out in a package. The package is divided into individual products using laser cutting. The paper provides a review of several published works devoted to the study of the structure and properties of tool steels after laser exposure. The developed method is protected by a patent of the Russian Federation.
