Manufacture of knives and their heat treatment
Bukvic, Tomáš ; Doležal, Pavel (referee) ; Němec, Karel (advisor)
This bachelor thesis deals with manual small series production of knives. It presents an overview of used cutlery steels and ushers their characteristics. It deals with the choice of blade geometry and material for a particular knife application. Furthermore, it initiates into the issue of heat treatment of knives, which is absolutely necessary for their functionality. The conclusion includes the documentation of the kitchen knife manufacturing process, which was made for the purpose of this thesis.

Cold weapons
Střechovský, Jan ; Němec, Karel (referee) ; Molliková, Eva (advisor)
The aim of this bachelor thesis is a summary of relevant information concerning cold arms. Concerning the amount of content of this topic, this thesis is focused on general knowledge regarding the types, usage and development of cold arms, with mentioning some interesting and less known facts. It also contains deeper analysis of some chosen cold arms or key parts in their manufacture process.

Material selection and heat treatment of blade knives
Mrňa, Tomáš ; Molliková, Eva (referee) ; Němec, Karel (advisor)
A good quality knife should have good cutting features and the edge should be resistant against blunting which can be achieved by using different materials. Steel is the most commonly used material for manufacturing of blades. There are 4 basic categories of steel used for blades manufacturing: unalloyed noble (class 12), low-alloyed (class 13-15), stainless (class 17) and special tool steel (class 19). The optimal combination of structure and features of the used material is achieved by tempering process. The goal of my work is to focus on the steel blade and to point out differences between materials used in mass production and steel used by cutlers. Including the possibility of using various unusual materials from already manufactured products. I am also trying to describe each kind of quenching and consequences of wrong processing.

Cutlery steels and their composition and properties
Lenghardová, Monika ; Kaňa, Václav (referee) ; Záděra, Antonín (advisor)
This paper is focused on the description of steels suitable for blades production in terms of their chemical composition, structure, properties and thermal processing. The practical part is focused on the assessment of particular selected tool steels manufactured by conventional procedures - AK5, N690 and RWL34 steel manufactured by powder metallurgy. There were carried out the two methods of thermal processing with all three selected steels and the subsequent assessment was performed on the basis of the results of mechanical properties testing - three-point bend and hardness according to Rockwell, including the metallographic assessment of material structure.
