The Kamakura period (1185-1333) marked the golden age of swordsmithing. Legendary swordsmiths like Masamune and Muramasa emerged, creating blades of unmatched quality. The Muromachi period (1336-1573) introduced the katana, a blade worn edge-up for quick draw and strike, becoming the samurai’s weapon of choice.

In the Edo period (1603-1868), the art of sword making was refined further, with an emphasis on aesthetics and craftsmanship. Swords from this era are highly prized by collectors and historians.
