Abstract: A jaw is provided for a vise which includes a sloping surface for supporting a work piece at a particular angle. The jaw includes a primary mass and a secondary mass which are either formed together as a single unitary mass or formed separately and coupleable together. The primary mass includes a front surface which extends vertically and acts as a surface to hold the work piece within the vise. The secondary mass includes at least one sloping surface which is oriented perpendicular to the front surface of the primary mass. The sloping surface has an angle matching that desired for the work piece. A set of different jaws are provided with each jaw having a secondary mass with a sloping surface of a different angle. The work piece has a surface thereof resting against the sloping surface of the secondary mass of the jaw so that the work piece is held at the desired angle within the vise.
