It is said that he learned under Kunikane the Forth. Masahide went to Edo and learned under Yoshihide
at the age of 22. Masahide became a retained swordsmith of the Akimoto family and studied the method of making sword
and disciplined pupils. A daimyo; a feudal lord gave Masahide foreign steel called Namban-tetsu to study.
He was fond of brilliant Toran-ba that had a tendency to break so he tried to the revival of Koto aimed at the sharpness.
It is an accepted theory that he was the founder of Shinshin-to.
There are various kind of his signatures pattern with Kao or Kokuin.
