Among Yamato regions, the most ancient lineage Senjuin @ appeared end Heian era (1100s) then major lineages of Touma , Tegai ~, Housho ۏ and Shikkake K occurred to form the five major lineages in Yamato province during Kamakura - Nanbokucho period.
Each group belonged to an individual Buddhist temple and exclusively worked and made for it's monk soldiers.
The Tegai ~ was the most biggest, powerful group that belonged to Todaiji-temple 厛. The founder KANENAGA i appeared Shouou era(1288-) and they set up their artier studio nearby ]Q Tegai-mon west gate of Toda-ji temple.
The name of Tengai ]Q had been converted into Tegai ~ - a name of sword maker group. Even present time, the name of town Tegai-cho L, Higashi-Kanenaga-cho i or Nishi-Kanenaga-cho i remain near the Tegai-mon gate ]Q.
In sword maker scholarship, the swords and makers are distinguished due to it's workmanship between Tegai ~ and Sue-Tegai ~ (on bafore Nanbokucho period is called Tegai ~ and those ones on after Muromachi is called Sue-Tegai ~).
According to the Nihonto Meikan, KANETOSHI r who belonged to Tegai ~ was a pupil of KANEYUKI s and being active Nanbokucho period (ca 1381-).
Among five lineages of Yamato, Workmanship of Tegai ~ shows reportedly the most strongest/brightest Nie both on surface and temper and it is convincing that this Tanto is given an expert opinion as a work of indivisual name of smith KANETOSHI r in Tegai ~ lineage.
This tanto emits incredibly bright of fine Nie that creates similar Soushu-oriented workmanship in vogue of those days like the famed smith Kaneuji who came from same Tegai ~ lineage.
