Things You'll Need
Instructions
Purchase a cotton cloth, sword oil, rice paper, powder ball or a sword cleaning kit that contains all of these items. Proper katana cleaning requires every single one of these items, so no substitution or skipping.
Hold the kantana carefully by the handle with one hand, with the sharp edge facing away from you. Carefully use the rice paper to wipe away any old oil from previous cleanings. Fold the rice paper over the back end of the katana. This will allow you to clean both sides of the blade while preventing your fingers from being cut.
Take the powder ball and lightly tap every one to two inches on the katana, making sure to coat the blade in powder. Repeat on the other side to guarantee a full finish.
Take the rice paper and rub the powdered katana. Start on one side and then the other, always wiping toward the back of the blade and never toward the sharp front. Repeat this process until all of the powder is removed from the katana.
Apply a small amount of sword oil to both sides of the katana blade. Only a few drops are needed, so don't overdo it. Wipe both sides with the rice paper to assure a bright shine.
Re-sheath the blade carefully. Make sure not to touch the blade after the cleaning; otherwise you will smear the finish.
