The Japanese sword carried on the harsh front suffered from rust. Therefore, a guidebook on how to care for Guntō has been published by a person who calls himself a sword expert. However, there should be no time to maintain the Guntō under the combat action of confronting the enemy. The feeling of the people involved in the home front after the gun, who preached how to care for the Guntō with the feeling of a Japanese sword for appreciation displayed between the floors, was nonsense after all. It was inevitable that a “rust-free Guntō” would be required to reflect this situation. Mr. Naruse’s description also mentions “fashionable stainless steel sword (name: Kanenaga)”, which proves that it was quite popular. The problem was even more serious in the Navy, which was exposed to salt damage at sea.
Army name: Rust-resistant steel sword
There is a commentary on the sharpness comparison between Japanese swords made of carbon steel and stainless steel swords, but it is a joke of an infant who does not even have in mind the environment in which Guntō is used. Originally, for practical swords used in poor environments, rust on the blade is a serious problem before discussing sharpness. It was clear whether a Japanese sword that rusts immediately due to rain or salt damage or a stainless steel sword that does not require rust prevention and maintenance is more practical. Sharpness was a secondary and tertiary issue. The Army suffered from rust on Japanese swords and rust on blood swords in a poor frontline environment. Against this background, stainless steel swords have become widespread. Stainless steel is a stainless steel (Steel), which is an alloy of ordinary carbon steel containing chromium (Cr) and nickel (Ni). Generally, steel containing about 11% or more of chromium is defined as stainless steel. This is because when the amount of chromium is about 11% or more, the rust resistance (corrosion resistance) is dramatically improved. There are four types of stainless steel depending on the composition of chromium and nickel and the metallographic structure.
