We just added a new nidai Hizen no Koku Minamoto Masatsugu (later Munetsugu) to the gallery. The blade is in polish and shirasaya with very nice koshirae and NBTHK Hozon paper. The hamon is full of activity and the blade is an all around knockout made by a jo saku smith in the early part of the 1600s, probably around the Kanei period.
