This is a gendaito by the smith Unshu Sadayoshi (貞善) using his first mei of Yoshitsugu (善次). He was a student of Gassan Sadakazu and later continued studying under the another famous smith of the time period Kawashima Tadayoshi. He was born in Like many of the better Gassan works of the time period, this sword shows very high class work in terms of both hamon and jitetsu. The hamon is a choji-midare full of activity and naturalistic variation. There is kinsuji everywhere throughout the hamon. The hamon has strands of bright nie running down, which I have tried to photograph here. Jihada is a really well done itame, thickly covered with jiinie and showing fine chikei. The blade has a strong and powerful sugata with a wide mihaba: nagasa 64.5cm, moto-haba 33mm and kasane 7mm. The blade is in shin-gunto koshirae with leather saya cover.
