Abstract
A method of breaking a rod of brittle material, such as a glass optical fiber, so as to yield a mirrorlike surface across the entire rod end is described. This is achieved by establishing a decreasing tensile stress across the cross section of the rod which, at all points, is greater than zero but less than the threshold stress at which a mist zone forms. This is conveniently achieved by simultaneously applying longitudinal tension to the rod and bending it. A convenient hand tool for breaking optical fibers is also described.
