3．Musashi ( 武蔵 ) in Edo ( 江戸 )
Both katana and wakizashi have a shallow sori (curvature). Often the upper part width of the body tends to be narrower. Often but not always, the hamon starts small irregular, gradually gets a little bigger irregular, then a few inches under the yokote line it becomes small irregular. The boshi is Komaru-boshi. The Ji-hada is somewhat rough. Masame-hada shows on Shinogi-ji.

- Satsuma (薩摩 )
The sword made in Satsuma has a solid look for both katana and wakizashi．Kissaki (the top point area) is stretched out a little. Yakidashi (a few inches above machi ) shows small irregular hamon. Hamon is O-midare with coarse nie called Ara-nie. The Ara-nie forms Togari-ba (pointed design, see below). One of the characteristics of this region is called Satsuma-nie. It means that the Ara-nie around hamon continues into the Ji-hada area, therefore the border of Ha-nie and Ji-nie is unclear. Inside hamon, sometimes shows a thick line shaped like lightning. This is called Satsuma-no-imozuru (sweet potato vine). This is the biggest characteristic of the Satsuma sword. Boshi has a narrow-tempered line with a small irregular pattern, this is called Satsuma-boshi. On the Ji-hada surface, a dark long line like chikei appears. This is called Satsuma-gane (薩摩金).
