The paper presents the characterization results of various types of steel component at the end of product life with the unknown chemical composition, mechanical properties and previously implemented thermo–mechanical treatment. This study was done aiming to examine the possibilities for reuse of some end–of–life agricultural and industrial steel products in order to obtain blades for knives in non–industrial conditions with appropriate and acceptable properties. Demanded shapes of the blades were obtained by applying various types of thermo–mechanical treatment. Chemical analysis of the investigated steel components was done using the energy–dispersive spectrometer. The microstructure was analyzed using optical and scanning electron microscopy. Hardness of analyzed steel scrap and obtained blades was measured using Rockwell C scale. The hardness values of the obtained blades (with optional quenching or not) indicate to a good selection of the steel end–of–life products for this purpose.
