ABSTRACT:
A tool is disclosed which facilitates the breaking of glass along a score line and is particularly useful for forming glass pieces of irregular shapes, such as those utilized in stained glass art works. The tool has a base on which is mounted a convexly curved fulcrum element. The convexly curved surface of the button provides the fulcrum point when it is placed beneath a glass piece having a score line on its upper surface. A second element of the device is a pressure block having a curved lower surface with generally the same radius of curvature as that of the convexly curved fulcrum element. The pressure block is placed on the upper surface of the glass such that its curved surface straddles the score line and, when the operator exerts a downward force, the glass is caused to fracture along this score line. The device is readily manipulated by the operator and greatly facilitates the cutting of narrow elongated strips of glass, or glass having a curved shape.
