HELP, FINGERPRINT ON BLADE!!!

[jutettsu8]

I noticed a fingerprint on the blade (on the backside), but i don't have any oils or equipment right now...

How can i prevent it from rusting??? This probably happened when i tried unseating the blade.

HELP...

Clean with alcohol, 99% no water and oil with a premium mineral oil. Unless you are in the middle of a desert there must be oil even at a corner store. John

the whole blade or just that part?

And there is nor rust yet.

It wouldn't hurt to clean and oil the entire thing except the nakago.

It would also help to know what part of the world you live....

If you live near a Walmart: get a can of denatured alcohol from the home area, some nice gun oil from sporting goods, and a microfiber cloth from eye dept.

Wipe the whole blade (other than nakago) with alcohol and microfiber cloth, then a light coat of oil. Good to go.

I found Olive Oil( extra vergine), would that work?

And i live in Europe

Hi Jonas, Certain organic oils can promote rusting, they actually have moisture in them. I suppose it could help temporarily ( a day or two) until you find some proper oil. Maybe, even some Dexron, auto transmission fluid, in a pinch. There must be a source of proper oil somewhere near you. John

and how long does it take until it starts to rust, Would it last a while until my choiji oil arrives ( which i trust more than other oils for this)

I would use good old 3 in 1 oil if there was nothing else until the proper oil arrives. Who knows, your area is dry? sea side? Wipe and reoil daily to allay worries, maybe. John

[jutettsu8]

My area is not so dry, but could the blade refrain from rusting when i don't oil it until the proper oils arrive, and just leave it for now?

I'm very worried about this so excuse me for asking so much.

Just use a lens cloth from your local optician.

Rust/the oxidation of iron is dependent on the composition of the sword, temperature and the humidity level. Room temperature and low humidty means slower rusting then keeping your sword in a Brazilian rain forest namely high temp with high humidity. High temps alone (100 F or so)will not rust metal if the humidity level is low. Hence old US airplanes sitting in the desert for decades without much rusting. Remember also that the composition of the air can make a difference. If you live by the ocean or in downtown Peking China( high pollution) you'd have more problems then in rural or suburban America. In any event, Nihonto will rust no matter what you do. All you can do is control the amount and the time required for such rusting

[jutettsu8]

The easiest thing right now and what i had in house (since it's evening) was to wipe it with a lens cloth.

(and i seriously don't trust any other oils for this matter)

Well your 'Choji" oil will be fine grade mineral oil with some clove oil mixed in. Read the posts on uchiko and oiling .

Not to get too paranoid or making the care overly complicated = read up - don't over oil either - enjoy.

Denatured alcohol , good oil , microfiber cloth - adjust to the humidity in your storage area and home.

the closest thing to choji oil at walmart would be butcher block oil, right? that should be food safe more or less pure mineral oil. perhaps with vitamid d.

 

also, is the microfiber marketed for cleaning your car the same as that marketed for glasses?

I would avoid the extra virgin olive oil. Might be a little acidic. Dont rub on that fingerprint too hard. It is better than having a buff mark. See if you can find a good, non-acidic metal polish. I use Noxon 7. It seems to be amonia based.
