Ancient swords that are manufactured in Japan like the katanas and the tachi are usually made of high carbon steel that is duller, grayer and has what appear to be imperfections in the steel.

 

Pattern wielding is the ancient process of forging these swords. Craftsmen repeatedly fold several layers of steel to create a homogenous blade. If a sword undergoes this process, then the Japanese sword sharpening procedure can restore it.

 

Ancient swords that are manufactured in Japan To protect an ancient sword, you have to constantly battle against moisture, rust and acid, so time and effort must be spent for its preservation.

 

Samurais in pre-industrial Japan make sure that these weapons are gleaming and in shipshape form since their lives depended on it.

 

These katanas or the like which were carefully maintained are thankfully still in its original disposition until today Japanese sword sharpening isn’t just grinding and wiping of dust, that only goes for the stainless steel replicas which would break if used the similarly to the carbon steel originals.

 

Choji oil, Uichiko powder and tissue paper (not just the kind you buy from a drugstore, mind you) are only some of the materials used in Japanese sword sharpening and should be chosen carefully.

 

The entire procedure covers the preparation, inspection of the probable damages like rust and acid, cleaning, oiling and storage of the sword. Japanese sword sharpening is more like a ritual rather than a daily chore.
