Nikolai says masters use various tools that have various purposes. Tools should be made from quality materials and honed correctly. Nikolai makes auxiliary tools himself. Tools that he uses are as follows: soldering tools, tweezers, a small metal barrel on which to engrave products, files, hammers etc. Nikolai recalls that when he was a child he received a metalwork set as a present. Today, by contrast, such sets for children are not produced anymore. Nikolai thinks that this set may have influenced his choice of his profession.
