The katana, an emblem of the samurai warrior and an integral part of Japanese history, represents the pinnacle of swordsmithing artistry. At the heart of this artistry lies the hamon, a visually striking pattern that forms along the blade's edge during the sword-making process. The hamon is not only an aesthetic feature but also an indicator of the blade's quality, revealing the mastery of the swordsmith and the spirit of the samurai.
