Unconventional methods of processing materials for knives
Bražina, Jakub ; Němec, Karel (referee) ; Doležal, Pavel (advisor)
This thesis focuses on the issue of unconvetional cutlery materials, their application for production, and the processing of a hunting knife. The readers are aquainted with cutlery issues in the search section, where the basic characteristics and properities are written. The next part describes the various metallic and non-metallic materials and their possible properities of processing and production. This thesis also deals with the surface protection of these cutlery materials. The second main part describes construction design, material selection, heat treatment, and with surface treatment of the hunting knife.
