Here, you will learn some simple tricks on how to maintain your blades and prevent rust.
Leather sheath or wooden scabbard absorbs moisture from the environment or from sheathing of a blade, leaving the blade susceptible to rusting.
Avoid touching blade with bare hands, as it will leave oils and salths that will eat their way into the blade and eventually leave pits. Immediately wipe off if blade is touched.
Keep a light coat of oil or renaissance wax on your blade when not in use. A heavier and more viscous coat may be necessary for long-term storage.
