Haven’t seen a naginata blade construction like this before. Shinogi zukuri on one side and Kata Kiri Ha style on the other. Posted 2 nice wakizashi with this blade construction last year by the way :
- Kata Kiri Ha Zukuri Wakizashi (Late Muromachi 1500-1550AD)
- +300 year old Wakizashi blade with pretty Horimono
Sagami no Kami Masatsune was one of the most influential Owari smiths of the early shino-era. More info on the man in Markus’s book : Nihon-shinto-shi – The History of the shinto Era of Japanese Swords.
