Although there are almost no modern examples of signed works by Amakuni, legend has it that the double-edged katana, Kogarasu Maru, was forged by this man.
In Japan, from the legendary time of the famous smith Amakuni, hamons were originally straight and parallel to the edge, but by the twelfth century AD, smiths such as Shintogo Kunimitsu began producing hamons with very irregular shapes, which provided both mechanical and decorative benefits.
