NBTHK
Hozon
Certificate
【Description】
This blade has a signature of Osafune Sukesada on the front and 17th year of Eisho in August in the back. The 17th year of Eisei is 1520 A.D, meaning it was forged 500 years ago.(the late Muromachi period)
Those who forged swords in the Bizen province(Okayama prefecture) at the end of the Muromachi Period(1492-1569 A.D) are called Matsu Bizen(Matsu mean the end). 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 Samura history. Bizen is the birthplace of Bizen Den,one of the most famous Japanese sword tradtion along with Yamashiro Den, Soshu Den, Mino Den and Yamato Den.
The swordsmiths in Bizen produced many swords during the Muromachi period as it was in the middle of the Sengoku period(Warring state period), and the demand for swords increased among strong feudal lords. The length of this blade is efficient and must have been easy for its owner to handle back then. It would be nice to have a piece that was forged in the warring state period, when there was so much rivalry between warlords.
The curvature of this sword is breathtakingly amazing to observe and this blade was originally made for one-hand use. We assume it must have been practical apply this blade in battle fields.
It comes with a Shirasaya case(traditional wooden case for the blade). If you look for sword mountings for this blade, we could arrange it with extra cost. Please feel free to ask for the detail us if you are interested.
