Katana - Aço japonês - Heianjo Nagayoshi - Japão - Katana Samurai Japonês por Heianjo Nagayoshi Mestre de Muramasa NBTHK Tokubetsu Hozon Certificado.

This Japanese Samurai Sword Katana is made by Heianjo Nagayoshi, an exceptional swordsmith known to be the mentor of the famous Muramasa, is a remarkable artifact from the Muromachi period, dating to around 1469. This katana, certified by the prestigious NBTHK Tokubetsu Hozon, stands out not only for its historical significance but also for the masterful craftsmanship that it embodies. Heianjo Nagayoshi was a prominent figure in the Yamashiro Sanjo school, working in Kyoto during the Muromachi period. Though several generations carried the name Nagayoshi, many of the earliest blades have been lost to time. This particular Nagayoshi, is believed to have been the teacher of Muramasa, a testament to his importance in the world of Japanese sword-making. The NBTHK Tokubetsu Hozon certificate notes that “Heianjo Nagayoshi forges a finer jihada (steel grain pattern) than both Muramasa and Masazane. ” His temper line (nioi-guchi) and surface steel (jigane) are bright and finely crafted. Nagayoshi’s work is distinguished by its dense ko-itame-hada (wood grain pattern) and radiant jigane, while the Sengo school, to which Muramasa belonged, often produced more striking itame-hada with darker jigane, sometimes featuring shirake-utsuri, a cloudy reflection on the blade. Respected sword scholars, including Fujishiro, hold Nagayoshi in high regard, ranking him as “Jo-jo saku,” signifying a master of high-level craftsmanship. Specifications:
