23 time line Sengoku Period

The circle indicate the time we are discussing in this section

After Onin-no-Ran, Kyoto was in a devastated condition.  Distinguished sword smiths in Kyoto area were almost all gone.  Sengoku Daimyo (warlord or feudal lord) demanded a large number of swords from nearby.  During this time, Mino and Bizen were the active swordsmiths.  It was because Mino province was located in convenient place for many feudal lords.  Alos, Shizu group from Yamato Den (school) moved to Mino province.  Tegai Kaneyoshi from Yamato Den moved to Mino and many swordsmiths from Yamashiro and Yamato area moved to Mino.  Thus, Mino could supply the high demand for a large number of swords.  During this wartime, Samurai demanded the practical swords that do not bend, break and cut well, very practical sword.  Together with Mino, Bizen Osafune swordsmiths fulfilled the huge demand.

Chumon-Uchi and Kazu-Uchi-Mono.

Kazu-Uchi-Mono was a sword made just good enough for one battle. They were not made for permanent preservation.  Whereas Chumon-Uchi was an order made swords.  Sound shape, good forging, often engraved the swordsmith’s name and the name of a person who ordered.
