Universal clamp for the reproduction of flat keys

In order to satisfy a growing market of more and more flat key models and the very fast reproduction needs of these keys, a universal vice to facilitate the machining of their teeth according to a key-model is developed. It comprises a lower plate (100) and an upper plate (200), the peripheral portion (120,220) of the opposite bases cooperates in the manner of jaws for clamping a longitudinal portion of a bit (22) of flat keys while leaving the other longitudinal portion of the blade (22) accessible. This vise is characterized in that said opposite bases are hexagonal and in that the shape of said jaws is different on each face of the hexagon, each of said forms of said jaws being compatible with the section of
