Renaissance wax is great to keep that high carbon steel knife of yours in great shape. After use, give it a coating of this, and you'll never have to worry about corrosion issues.
"Renaissance wax is a microcrystalline wax polish that is encountered in antique restoration and museum curation. It is not appropriate for all materials, and is most safely used on metal objects. However, it is also used for the polish and conservation of organic materials such as wood, ivory, tortoiseshell, and gemstones. Renaissance Wax is sometimes used by reenactors of historic swordsmanship to protect armor and weapons. Waxes are more protective and longer-lasting than oil, especially for swords and helmets that are frequently touched by human hands It has recently been introduced in the world of guitar building, as a finish that protects and gives colour to the wood."
