The blade was polished.
Habaki : Gold foiled single habaki.
Blade length : 69.2 cm or 27.24 inches.
Sori : 1.9 cm or 0.75 inches.

Width at the Kissaki : 2.22 cm or 0.87 inches.
Kasane : 0.64 cm or 0.25 inches.
Era : Late Edo period.
Shape : The blade is oosuriage mumei and wide and thick with deep sori nice looking shape.
Jitetsu : Koitame had well grained with jinie attach.
Hamon : Niedeki gunome midare wildish sunagashi and kinsuji scatter.
Special feature : Suishinshi Masatsugu was working at Late Edo period and he was a student of the Taikei Naotane and also studied from Suishinshi Masahide.
He was said that he got married with Son-in-law if the 2nd generation Suishinshi masahide.
He was influenced a lot from Naotane and made Soden bizen style(mixed up sosyu school and Bizen school cyoji midair hamon)
The previous NBTHK Kanteisyo was Norishige but recently the blade was judged as Suishinshi Masatsugu.
The blade is high grade Soden bizen style active wild feeling sword.
I think the sword was cut shortened by some bad guy as Koto Norishige Saijyo saki sword.
The blade is koitame hada and active hamon.
I think the blade looks Edo shinshinto sword. So we sell the sword as Suishinshi Masatsugu not Norishige.
