Sengoku Seki was an industry: smiths organized under their tutelary Kasuga shrine, arming the war bands of central Japan. Magoroku Kanemoto’s sanbonsugi and the finest Kanesada work prove quality survived inside mass production.
This antique tanto is made by the Jumyo school, originating from the Mino tradition. Signed by Jumyo, a name meaning 'Long Life', these swords were often given as gifts among samurai. The blade comes with koshirae and is certified by the NBTHK.
