All metal parts of your sword, including the wire wrapped handles should always be covered with a light coating of oil to prevent rust. You may also want to wipe it with a silicone coated gun/reel cloth. Many people prefer the gun/reel cloth because there are fewer tendencies for dust to accumulate and trap oxygen to cause pitted areas in the blade. Wooden handles should be treated with a light coating of lemon oil or tung oil to help prevent cracking. Leather scabbards, sheaths and covered handles should be treated with a good leather paste wax. The scabbard can also be treated with neatsfoot or mink oil for waterproofing, although this is not recommended for gripping surfaces. Do not store your sword in its scabbard for long periods of time since the leather traps moisture, which can produce rust spots on the blade.
