Greetings all. I've got a situation where I *need* to repair a 50 foot cat 5 cable - went out and bought a $70 crimping tool, with a picture of a cable and cat 5 head being crimped on the fron of the package, and it crimps... jacks. SO. Is it possible to manually wire a cat 5 head with say, a knife and a jewelers screwdriver? If so, detailed description would be great as I've never crimped anything like this before... Muchas gracias!
