Where was the first samurai sword made?

The first samurai sWords, known as "katana," were developed in Japan during the late Heian period (794-1185). The craftsmanship evolved in the regions of Japan, particularly in areas with a rich tradition of sWord-making, such as the Bizen province. These sWords were designed for the unique needs of samurai warriors, emphasizing both functionality in battle and artistry in design.
