This katana is by Yokoyama Sukekane, adopted son of Yokoyama Sukemori, and a prominent smith of the Shin-Shinto period from Bizen province. He signed his blades as '58th Generation Descendant of Tomonari' to claim lineage to the founder of Bizen smithing. The blade features a well-forged ko-itame hada and a nioi-gachi choji midare hamon, with a rare hirazukuri construction despite its long nagasa.
