Mark with Japanese Mark: 文雄 "Fumio" | #458155

文雄 "Fumio". This mark is from a menuki, which are small decorative pieces placed under the binding of a sword. They serve several purposes, such as improving grip or providing good luck. This menuki was made by Fumio, who worked as a sword engraver (soukenkinkou) in Dewa Province (present-day Yamagata Prefecture). Soukenkinkou is the Japanese name for metalworkers who design accessories for bladed weapons.
