About This Project

Japanese swords represent premium quality and sharpness worldwide. Traditional Japanese craftsmanship realizes the utmost excellence. The same traditions bring greatness to the Panasonic shaver.
Our challenge was to use this outstanding craftsmanship to forge a Japanese sword from Panasonic shaver steel. Shaver blade stainless steel is extremely hard and difficult to fabricate. Our traditional swordsmith faced a surmountable challenge.
