All knives require, if not careful, then regular maintenance, so that they remain sharp and beautiful, do not get covered with dust and, in the worst case, do not rust. Protecting wax is a kind of material for polishing and knife care. It is used to protect the wooden handle of the art knife from changes that can be caused by heat, severe cold or active daily use. As a result of wax treatment, the wood absorbs it and receives a protective layer, which also renews the appearance of the handle.
