Our Fiber Optic Deluxe Diamond Scribe features a retractable, 60 degree cone point and is housed in a deluxe metal casing. Scribing Tips: Once the epoxy is cured or hardened, the protruding fiber should be scribed as close to the ferrule tip as possible. Use your fiber optic scribe tool to make a light scratch on the fiber. Take care not to break the fiber off when scribing as this may result in a crack in the core of the fiber optic endface. After the fiber is scribed, use your fingers to gently pull the fiber upward to break it away from the fiber optic connector ferrule. Also see our other fiber optic tools and supplies for fiber optic splicing and termination. These include fiber optic cleavers, fusion splicers and mechanical splices. Cable preparation supplies include fiber optic stripping tools, alcohol wipes, Kim Wipes, icky pic removers, solvents, and more.
