What is Katana makura in Japanese Katana terminology?

"刀枕" or "Katana-makura" translates to "Sword Pillow" in English. It is a tool used in the appreciation and maintenance of Japanese swords. When the blade of the sword needs to be temporarily placed down, the sword pillow is used to separate the blade from the surface of the table or desk. This helps to protect the blade from potential damage and also makes it easier to handle during the maintenance process.
