Tetsunosuke Miyano (1901–96), a second-generation nokogiri-kaji—or sawsmith—from Miki City, Hyogo Prefecture, was one of the few sawsmiths who was capable of making saws using tama-hagane. Tama-hagane is a refined steel smelted from the Japanese method of manufacturing steel using a tatara, a traditional furnace. In the Edo period, all steel used was tama-hagane—however, with imported steel becoming more widespread, it gradually disappeared after the Meiji era. Despite this, Tetsunosuke, who was born into a family of sawsmiths, continued making saws using tama-hagane even after the war. Here, the craftsmanship of effortlessly manipulating the steel is revealed, built on the foundations of a tōshō, or swordsmith’s, skills. In this exhibition, we introduce this craftsmanship alongside numerous works.
