Abstract: A glass cutter for fracturing prescored sheet glass includes a C-shaped frame having in one end a glass supporting anvil and at its opposite end a screw operated breaker point. The glass sheet is positioned on the anvil with its scored line centered over a V-grooved channel in the anvil surface. A breaker screw is rotatably threaded in the opposite end of the frame and the screw which is perpendicular to the glass surface is provided with a breaker point that is brought into contact with the glass surface and then very slightly rotated to fracture the prescored glass along a very short length of the score line. By repeating these short fracturing steps, very intricate shapes may be cut in the glass without accidental breakage thereof.
