The light is cut once on the way out and the second time on the return trip. This has become the most popular type of tester. A "Slitless" tester. A pinhole is used by some for various reasons, but it will work with or without. Mine is just a green LED half covered by the knife edge. -------------------- Clear Skies and Good Health, Mitchell.
