The process of maintaining the edge of a Japanese sword is a highly specialized skill. It involves a sequence of steps using progressively finer abrasive stones to refine the blade’s profile and achieve a keen cutting surface. The objective is to remove microscopic imperfections and create a consistent, sharp edge along the length of the blade.
Proper edge maintenance preserves the integrity and functionality of the weapon. A well-maintained blade performs optimally, reducing the risk of damage during use and upholding the historical significance of the craftsmanship. This practice reflects respect for the art of swordsmithing and ensures the longevity of the blade.
