Previous answer is
Bishu Osafune Sukesada (Hikobei no Jo Sukesada)
A day in February, Eisho 6 (1509)
備州長船祐定(彦兵衛尉祐定)
永正六年二月日

Features: As you may know, inscriptions including a secular name began from the period of Hikobei Sukesada onward, and it is believed that such names did not exist before this time.
Please particularly note these carvings.
Furthermore, the finely detailed midare hamon, the utsuri, and the dynamic midare-komi boshi together form a truly remarkable temper pattern.
These points are described in detail by Tanobe Sensei on both sides of the sayagaki.
Tanobe Sensei identifies the smith in the sayagaki as Hikobei Sukesada, the father of Yosaemon Sukesada.
