The sword cleaning oil is suitable for any bladed weapon. Our Choji Oil is the traditional Japanese method for sword cleaning and maintenance. It has been used for centuries and is proven. Please be aware that some sword oils from other countries for example China may contain the wrong oil. I have seen Chinese cleaning kits that contain strange looking oil that is not Choji. Our Choji oils are the traditionally used Japanese ones. We import them directly from Japan. Please do not use other oils as they can rot, corrode or even coat the blade in a plastic layer.

Carefully maintaining your sword allows for it to bring you enjoyment for the years to come and even for future generations. The Japanese samurai saw themselves as temporary custodians of their swords, and it was important to pass on the sword in its original condition or better. They believed that when they die, the sword would end up in the hands of other owners who must also pass on this legacy.

Real swords are generally made of a medium to high carbon steel and low-alloy in nature. Unlike stainless steel (which is high alloy in nature) the simpler steels are vulnerable to oxidation, and thus a thin coat of oil would prevent this.

The ancient Japanese have been using choji oil for centuries and it is time proven. By examining Japanese swords today, swords hundreds of years old look as they did the day they were made.

Be careful not to get oil under any cracks or openings at the hilt where it can potentially trap moisture. With Japanese swords, it is advisable to remove the blade from the hilt, to clean and remove all the old oil before applying the new. With European and Chinese swords, sometimes it is not possible to disassemble the sword without unpeening the tang, so proceed with caution.

A few drops will do, and spread it with a lint free clean towel. All you need is an extremely thin layer of oil that serves as a micro-thin protective layer between the steel and the elements.
