The antique sword business is without a doubt booming, but it’s unlikely you’d want your own swords to have the antiquated look ahead of its time. It’s easy to feel overwhelmed by the sword caring advice out there, some of which is just plain wrong, counterproductive or misleading.
You may come across articles which advise you to use WD40 to prevent rust on your newly purchased sword. However, an experienced sword collector would most likely advice against such a choice. It’s easy to understand why a beginner might be confused.
Truth be told, there is no one fit all solution that will help care for your sword. The best method depends on the type of sword, how it’s being used, how it’s being stored and the climate and conditions the sword is subjected to.
There are a few basic tenants of sword care which you can use to find the best solution for your unique circumstances.
One of the few good points about owning a stainless steel is that they are pretty much rust resistant, which means you only need to wipe them down and occasionally reinvigorate the shine with a spot of window cleaner.
If you own a much better quality functional katana or other type of sword that is made from carbon steel then you need to give a bit more consideration to preventing rust. You’ll often find that sword manufacturers will coat newly forged swords with allot of grease, this is to prevent rust while the sword is stored or during transit.
When you receive your new sword one of the first duties which you’ll want to perform is to remove the manufacturer applied grease. This is easy to do with a lint free cloth and a spot of rubbing alcohol.
Quick word of warning, take care when cleaning. A new sword is likely a sharp sword and can easily cause injury for those not paying attention. This is one job where you’ll want to have your full attention on the task at hand, especially if you’re new to handling swords as they can be cumbersome.
You’ve cleaned your sword and you now have a shiny beautiful katana, but the blade is now vulnerable to the elements, so it’s time to apply some oil. But what oil works best?
The truth of the matter is that it doesn’t really matter too much, as long as you always have a thin layer of oil on your blade, the sword will remain protected.
What you decide to use will probably depend on what you can get your hands on. We can definitely recommend the following commonly available oils:
It is possible to get something called sword oil, but in our experience it’s less effective than the options above, costs more and can lead to rust, so there’s no reason to not get one of the cheaper alternatives above. The important thing to remember is to always ensue that the oil hasn’t dried up, so until you know how long an application of oil will last, it’s a good idea to check regularly.
Choji oil is the traditional oil used oriental swords, and it’s essentially just mineral oil with a bit of clove oil added for fragrance. It’s not necessary and you’ll not be missing out if you can’t get your hands on it.
How frequently you’ll need to oil your sword will depend a great deal on your climate. In a temperate zone you might find that a monthly application is more than sufficient, if you’re in a humid environment, you may find yourself reapplying oil weekly.
If you’re looking to store your sword for a long period of time, you’ll know doubt want to consider some of the longer term alternatives.
One very easy and cheap option if to cover your sword in a liberal coating of petroleum jelly (Vaseline), just get the store own brand stuff, it does the same job. Once coated, wrap your sword in oily rags and store it in a dry cool space. You’ll still want to inspect the sword periodically, but this treatment should last at least a year.
If you can get your hands on it, Renaissance Wax is a brilliant option for long term storage.
Renaissance Wax was developed by the British Museum for exactly the purposes of long term storage, so it definitely works.
To use renaissance wax you simply apply a small amount using a cloth. The beauty of the product is that it dries hard, and will protect your sword from rust for years. It’s dead easy to remove as well, a small amount of rubbing alcohol and a few minutes work will take it off. You can buy renaissance wax from amazon here.
It goes without saying that if you use your sword it’s going to end up with scratches, there’s just no avoiding it.
For every day shallow scratches, I cannot recommend Metal Glo enough. It just works, and it’s perfect for polishing and buffing out small scratches. Having tried several other similar products none have come close.
