The composition of carbon steel katanas makes it very susceptible to rusting. In fact, sometime it is the simplest factor that you can use to determine that your sword is genuine carbon steel. The proper care and maintenance of swor= ds is critical if they are to retain their condition.

CAR= E:

Critical! Do not subject or leave your sword in high temperature areas or in direct sunlight. The wood on your saya can absorb moisture from the environment or from sheathing of a blade immediately after cutting. The trapped moisture m= ay be released when the saya is subjected to high temperature and end up on yo= ur blade. Leaving a sheathed blade in sunlight or elevated temperature can qui= ckly stain and rust the steel.

Keep a= light coat of oil on your blade when not in use. A heavier and more viscus coat m= ay be necessary for long term storage.

When handling the sword, try not to touch the blade surfaces with your bare hand= s or other wet or moist materials (especially if its acidic). If done, please cl= ean and re-oil your blades immediately.

When s= toring the blade in its scabbard, spraying some water displacement solutions (WD 4= 0) into the scabbard to remove any moisture on the inner surfaces of the scabb= ard. Then store the blade in a cool, dry place out of direct sunlight.

Reg= ular Maintanence:

A sword cleaning kit is absolutely necessary for the maintenance of your katana. If= you do not own one, make sure you get one as soon as possible.

Our sword maintenance kit includes the following which is necessary in the proper care of your katana:

Brass Awl and hammer to dismantle the sword
Rice paper for cleaning oil from the blade, polishing and spreading oil on the blade
Extra large uchiko (powder ball), the pad contains non-abrasive powder that absorbs extra cleaning oil
Bottle of choji oil, to prevent rust= ing
Plastic container to store oiled clo= th

Bef= ore you begin - Caution: The blade of your katana is extremely sharp and may cause serious injury. M= ake sure that the blade edge is never in a position where it could injure yours= elf or others.

Mai= ntaining your Katana:

The sc= abbard of your katana is finished in many coats of black lacquer. To preserve the sheen, the scabbard needs only to be wiped occasionally with a very soft cl= oth. Handle the scabbard only by holding the wrapped section; otherwise fine scratches caused by handling the lacquered sections will dull the finish.

Bla= de Maintenance:

First, use a sheet of rice paper to remove oil from previous maintenance, holding the edge away from you and working v= ery carefully to avoid injury. (Note: if you wish to save the rice paper, a soft cotton cloth may be substituted).

Then tap the powder ball lightly against = the blade every two inches or so along its length, dusting the blade very light= ly with powder. (Note: when using the ball for the first time. You may need to= tap the ball against the blade a few times to "start" the powder flow through the fabric of the ball.) Then use a clean piece of rice paper or co= tton cloth to carefully rub over the powder to polish the blade. Repeat until bo= th sides of the blade have been polished and the powder is removed. Do not inh= ale the powder.

(If oil and powder is not enough to remove debries adhered to the blade, you can use a paper towel wetted with either water or solvents to clean the blade surface. thoroughly dry, and repeat the maintanence process from the beginning).

Apply = a few drops of oil along the length of each side of the blade and use a piece of = rice paper or cotton cloth to spread the oil evenly over the blade. Be sure not = to touch the blade again before resheathing.

Sta= in Removal/Polishing:

1. = Stain Removal - Should your sword be stained or show beginning signs of rusting, there ar= e a few things you can do to restore the condition of your blade to its origina= l.

If the stains are light, try using a pencil eraser to see if the stains can be removed. This only works for very very light stainings.

For he= avier stains, you will need to use wet sandpaper between 600 and 900 grit (depend= ing on the particular blade) to take off the staining. Sand it wet and parallel= to the blade until the stains have disappeared, then dry thoroughly and re-oil immediately.

Should= the blade become so corroded that 600-900 grit sandpaper does not work, your bl= ade probably have developed some pitting. Most minor pittings only effect the b= lade cosmetically, should the pitting be extensive, you may want to consider retiring the blade and find a replacement. (Our sword are priced so that it= is often better to simply replace the blade rather than to try to restore it).=

2. Polishing - If you want to give your blade a higher level of polish, there are several things that you can do and several that you should not do.

DO NOT USE A MECHNICAL BUFFING WHEEL - Though this = may seem like a quick and simple solution, the cutting edge and niku of the bla= de can be adversely effected by machine buffing. At minimum, you will take away some material on the cutting edge and dull the blade.... It may not be noticable initially, but it will reduce the cutting ability of your sword. = (You will start to notice when your rate of successful cuts diminish.

We rec= ommend a hybrid polish if you absolutely must repolish your sword. This is done by using progressively finer and finer sandpaper (starting from about 900 grit= to 1500 grit), wet sanded parallel to the blade on the MUNE of the sword ONLY. Then finally finishing off with light hand buffing using a compound such as Metal-Glo.
