Sukesada (祐定) is the great name of late-Muromachi Osafune, the most prosperous of the Bizen forges that scholars group together as Sue-Bizen. The signature was carried by a body of smiths so large that the early-modern reference Hayami-dashi lists as many as twenty-one who appended a zokumyo (common name) to distinguish themselves, and the published commentary is blunt that of all the late-Osafune families the Sukesada line was the largest and most productive. Two registers of work issue from this single name. Learn more →
