Nobutoshi was a member of the Kuroda clan, called Seiwemon, and lived in Himeji. The first generation around the Tenna period was signed 'Yamashiro-no-kami Fujiwara Nobutoshi' and the second generation around the Genroku period was signed 'Yamato-no-kami Fujiwara Nobutoshi'.
According to the Kuroda Family History compiled by Kaibara Ekken, a scholar who served the Kuroda family of the Fukuoka domain during the Edo period, the birthplace of the rare military strategist Kuroda Kanbei(Kan-pyo-e) is also said to have been in Himeji.
Although not showy, this Wakizashi is interesting when considering the samurai's preference for swords in the mid-Edo period.
[ Conditions ] There is a prominent area of o-hada around Shinogi-suji (3-5cm above the front machi).The arrangement is such that the mekugi is inserted from the back, and the tip of the mekugi comes to the place where it is hidden at the beginning of the hira-maki of the handle thread on the front. Therefore, the trick is to push the mekugi puller shallowly into the back of the handle thread from the front.
