This blade is Gassaku, a joint work by Kanetsugu and his pupil, Yoshitsugu. Gassaku swords are quite rare. It is also gigantic.

Akamatsu Taro Kanetsugu,a Kyushu smith, was born in Showa 26 (1952/1953). He is the son of swordsmith Kimura Kaneshige, and the oldest of the three Akumatsutaro brothers, the other two being Kaneteru and Kaneyoshi. He was a student of Tanigawa Moriyoshi when he won the Nyusen and Doryokusyo prizes at NBTHK swordsmithing contests. He has since won the Nyusen prize nine times. He is well-known for making large patterned and extravagant works that have a close resemblence to famed works from the Nambokucho period, the Soshu/Bizen school or which are reproductions of Minamoto Kiyomaru. This particular sword is very, very similar to a Soshu Ichimonji naginata-naoshi katana sold by Christies in November 2011 that was attributed to Kamakura Ichimonji Sukezane (circa 1250). The Sukezane went for 70k

Yoshitsugu is the pupil of Kanetsugu and is of the Tanigawa Moriyoshi. Yoshitsugu has won a Nyusen prize and Doryokusyo prize.
