Special feature : Founder of Enjyu school started by student of the Rai Kuniyuki. From late Kamakura period to Nanbokucho period, this school was worked at Kikuchi go by famous sword makers Kunitoki, Kuniyoshi, kuninobu and others.
This school is very similar with Rai Kuniyuki and Kunitoshi.

It is very healthy without Kizu.
