FIELD: process engineering.
SUBSTANCE: this invention can be used for making of knives for cutting machines. Said knife has main part (10) of first material (12) and cutting part (20) of second material (22) with at least one blade (24). Second material (22) has higher hardness as compared with said first material (12). Cutting part (20) is connected with said main part (10) along the butt (26). Proposed method comprises the steps that follow. Base (30) is made from third material (32) of high heat conductivity. Main part (10) is laid on base (30) so that datum surface of the main part (10) and base top surface are arranged, in fact, in parallel while butt (26) adjoins the base (30) top surface. Cutting part (20) is made by building second material (22) on first material (12) along said butt (26). Base (30) doubles as a mechanical support for second material (22) being built on. Cutting part (20) is finished to make at least one blade.
EFFECT: higher durability, longer life.
