Previous answer is
　 Nagamitsu
長光

Special Features: Nagamitsu was one of the most renowned swordsmiths in Bizen,
known for training many disciples and fostering notable swordsmiths like Kagemitsu,
Chikakage, and Masanori. Nagamitsu, a son of Mitsutada, belonged to the Osafune
school and was a significant figure in Bizen swordsmithing. He carried the title "Saemon
no Jō" and was traditionally believed to be the second generation, succeeding
Sukezane, but some experts suggest he might have been the first generation according
to the opinions of the Fujishiro family. Initially, Nagamitsu's works exhibited o-choji (large
clove-like) hamon, later transitioning to a quieter, straight temper pattern. Among the
extant famous swords, few possess the exceptional quality seen in Nagamitsu's works. It
is believed that the production of these swords was not solely the work of Nagamitsu
himself but involved collaboration with other skilled swordsmiths who diligently
contributed to their creation. During that time, Nagamitsu was highly popular and well-
known among the daimyo families, resulting in a custom of vying to keep his swords.
