Clipper tool

The device has display devices i.e. LEDs, crimping dies for crimping optical waveguides, and a trimming mechanism for trimming ends of the optical waveguides. Plugs are arranged in a retainer of a tool, where the device outputs information associated directly or indirectly with cutting executed during blade exchange. Pins (101-103) are projected from a housing (100) and aligned parallel to each other. An electronic circuit (105) is designed such that a signal is generated during closing of the tool. The trimming mechanism has a pressure disk that is mounted at a distance from a stop. An independent claim is also included for a tool i.e. pliers-like tool, for processing optical waveguides.
