Tips to Care Damascus knife: Damascus steel as well as 1095 high carbon steel knives are different than some other common steel knives because of its high carbon content they can be rusted if not care properly. If you have seen rust accidentally then use WD40 to remove it. Never store your knife for long time in leather sheath. Leather can absorb water which will rust the knife. Always clean the blade after using and apply oil or wax (please use cooking oil on Chef Knife) before you store it, for its longer life and durability.
