A Word from Aoi Art: This set of large and small Inseki-tō Hitokuni Hirotsugu Saku was crafted on the same day in the early autumn of Heisei 2 (1987), reflecting the strong intention of the swordsmith to produce a matched pair. Perhaps aimed at Nagayoshi or Hasebe-style works, the results are magnificent. The presence of this set differs from ordinary swords, with the jigane showing a unique and enigmatic aspect, making it a remarkable piece. It is rare for swordsmiths to successfully produce swords using meteorites due to the difficulty and scarcity of materials. Nakahata Mitsugu managed to locate and use meteoric iron to create these extraordinary swords. Meteoric iron contains a high level of carbon and is quite brittle, so it is challenging to forge. These two works, masterfully crafted from meteoric iron, are a testament to the swordsmith’s skill and dedication. We highly recommend these remarkable pieces.
