This genuinely made Nihonto samurai blade from the Yamashiro School of sword making has a place in history as it was made by the Damiyo Lord Yamamura Yasunobo who lived in Echizen Castle and the surrounding area of Echigo. He invited the reknowned sword smith Nobukuni to his home with the goal of learning the ancient art of sword making and eventually learned this art and fashioned this blade and was allowed to take on the sword smith family name of "Nobukuni ", specifically Yamamura Yasunobu Nobukuni. The Provenance and Contestation papers are from the main governing sword preservation society in Japan known as NBTHK and has the Token Honzon designation as a blade worthy of preservation.
