Abstract
A hand tool for cutting or scoring glass in which an elongated rigid finger piece is provided with an elongated handle secured at one end and a glass scoring member at its opposite end. The finger piece is of somewhat triangular cross section with a flattened top portion and inwardly curved side portions. A cross bar on the finger piece between the handle end of the finger piece and the handle extends outwardly on each side of the finger piece. In use the handle is slipped between the index and middle fingers of the user until the cross bar bears against the palm and the index and middle fingers bear against the top of the finger piece. The finger piece is then grasped between the user's thumb and ring fingers within the inwardly curved side portions.
