Hamon :From the hamachi area, Niedeki suguha
and then sudareba hamon active work with thick nioikuchi double hamon and triply condensed hamon and sunagashi work.
Special feature : At late Muromachi period, Kanemichi who was working
at Mino province moved to Settsu province with his students.
Tanba Kami Yoshimichi (Kyo Tanba first generation) was making swords
and after that departed 2 school Kyo and Oosaka tanba.
These school made Sudareba hamon mainly.
These school had kept sudareba hamon as the top secret of these families.
In fact, even right now, it is very difficult to make this kind of Sudareba hamon
and we have never seen this kind of Hamon even right now.
Probably If some sword maker who can make sudareba hamon, he will make Sosyu den easily.
Anyway the 3rd generation sudareba hamon is quite nice and active hamon.
