Giving a sudden powerful pull may not only impair the opening of the saya but also might result in an uncontrollable jerk leading to injury. Holding the blade still, pull it entirely out of the saya very slowly making certain the cutting edge never faces down or sideways. When you are examining a blade, you may support it with a piece of cloth or rice paper. Under no circumstances is the blade ever to be touched with bare hands or fingers. The acidic natural oils can cause rusting of the blade.
Some people advocate the wearing of white gloves when handling a blade.
This is a good practice. The tip of the sharp edge facing up must first rest gently on the opening of the saya . Again, holding the blade still, slide the blade along the channel into the saya . As before, the cutting edge must not face down or sideways. Return to top of page.
