Disclosed is a tool for making precise radial slits in the exterior of a cylindrical object, such as a coated optical waveguide filament. The tool has an interior passage and two blades to make radial slits. The blades are kept from penetrating too far into the interior passage by shims having a calculated thickness dependent on the angle separating the blades and the size of the interior of the object which is to be left uncut.
