Do not touch the blade
The oil in your finger tips will be applied to the sword's blade. If the oil is not wiped clean the shape of
your fingertips will be displayed on the blade. This can eventually become rust.
Keep the blade dry
Moiture on teh blade is very distructive. The following photos illustrate how surface rust forms on the
blade when exposed to moisture for a period of time.
Do not oil the blade
The metal used on the swords tends to absorb chemicals. Unlike other knives and swords, when oil is applied
to a Samurai sword the blade tends to absorb it. This is not a good thing as it creates a cloudy appearance
on the body of the blade. This coat can be difficult and/or time consuming to clean.
