Period: Shinshinto, dated December 1865.
Boshi: close to ichimai
Mei: Iwakuni sanroku Seiryuken Moritoshi tsukuru kore
Ura nenki: Keio gannen kinoto ushi jyunigatsu hi (December 1865)
This is a katana I restored earlier in the year by Seiryuken Moritoshi.
Moritoshi was a Shinshinto smith who was part of the Chounsai Tsunatoshi school, one of the most influential schools of the period. Koyama Munetsugu, Unju Korekazu and Takahashi Naganobu were all students of this school and all went on to establish there own important piece of sword making history.
The workmanship in this blade shows many similarities to that of Tsunatoshi, as you’d expect. Tsunatoshi was very skilled in producing both chojiba and toranba, and it seems Moritoshi has applied both of these styles within the hamon of this particular sword. A mixture of choji-midare, gunome-midare and toranba in nie-deki, there are ashi, sunagashi, delicate kinsuji and some interesting yo activities. It’s also interesting how the tobiyaki in the areas of toranba are still connected to the hamon by a thick branch of nie, it resembles a water droplet just about to fall.
The boshi is verging on ichimai which is unusual for this smith, it’s very well executed though, containing a thick nioi-guchi and hakikake.
The jigane is ko-itame with fine chikei and a hazy shirake-utsuri in places.
The sugata is typical for this smith/school – torizori with a wide mihaba and largish kissaki.
Moritoshi was a smith who has clearly been influenced by Bizen-den, but in this case is not intending to make a koto period Bizen copy, instead combining different techniques that were passed on from the Tsunatoshi school in order to create his own uniquely blended style.
