The invention relates to a method of making a die set for the manufacture of specially shaped ceramic tile, and the tiles formed thereby. A main component of the die set is a lower punch made of rigid material, on whose upper surface a profile is cut which is suitably shaped to form the front face of the ceramic tile, including the contoured side. The punch has a complete, continuous coating of synthetic resin or rubber bonded to it, with the punch's upper surface defining the form of the front face of the ceramic tile. The coating is continuous and covers the lateral portion of the profile that forms the shaped side, and continues on the upper most part with a horizontal edge which is turned externally with respect to the profile, upon the upper lateral surface of the body of the punch; furthermore a rigid body is fixed above the upper lateral surface, which acts to clamps the horizontal extension of the coating against the lateral surface.
