Shape: Shaped like Nagamaki, but it used to have Shinogi. It has to be older than it looks now.
Jigane: Itamehada is mixed with Mokume with Jinie. Utsuri appears.
Hamon: Apparently it looks like Ichimonji works. Chojimidare and Gunomemidare in the front remind us of Ichimonji very clearly. The Hamon gets down a little bit from the middle, and it became extreme Chojimidare mixed with Gunomemidare with Kinsuji from Monouchi.
Special feature: Senjuin school belonged to a temple that was near Senju-valley in Wakakusa mountain in Nara. It is known that this school is the oldest among Yamato 5 schools. The Hamon of this work is truly wonderful with its similarity to the Ichimonji school works on Kissaki.
