 Sukesada school was one of the most famous schools and it flourished for generations among Osafune schools(The head branch). There were various styles forged by the generations of Sukesada during this period. There were about 60 swordsmiths who used Sukesada as his maker’s name in the Samurai history.

NakagoNakago is the hilt of the Japanese sword. There is the inscription on this blade. It says “備前国住長祐定”(the maker’s name) on the front and “永禄二年八月”(the year the blade was forged)on the back.

Japanese swordsmiths left the black rust on the tang because it prevents red rust while the tang is in its handle. And the discoloration of the tang was created over time, and it is a great indicator for a Japanese sword specialist to estimate when the sword was forged.

 Two different types of family crests are designed. The flower-shaped crest comes from Nadeshiko (fringed pink), one of the seven autumn flowers in Japan. Its plain and pretty flowers have been appreciated since a long time ago and put as a part of decorations of clothing or furnishings. Several Samurai used this flower pattern for their family crests.

 Another geometric design crest is called Hikiryo-Mon (引両紋); it is a simple pattern with two horizontal lines in the circle. In ancient times, Samurai families had a custom marking the flag with a god’s name and drawing a black bar below it. By doing this, they prayed to Shinto spirits; their luck in a war would last for a long time. However, the custom was gradually changed its manner, and only the black line has remained. Because of this history, there is a close connection between Hikiryo-Mon and Samurai families. It is also said these lines represent dragons. As the dragon pattern has been treated as an auspicious design, it is possible to compare lines to this sacred beast. Takauji Ashikaga, who opened the Muromachi government, used Hikiryo-Mon for his family crest.
