The Yamato Tegai School was one of the major sword producers of the Kamakura Era. The school received its name because they worked in front of the Tegai gate of the Todai-ji Temple in Nara. Eventually the power of the temples weakened due to the repeated conflicts of the Muromachi Era, and the smiths eventually lost their patronage. As a result the school fell into decline. In approximately 1555 two Tegai smiths, Shinya Masanaga and Fujiwara Masanaga, moved their center of sword production to the Kanabo area of Nara to found the Kanabo school.

It would be worth sending this tanto to shinsa.
